ABSTRACT
A preliminary checklist ofpreviously published works on the benthic marine algae of
Samoa(l3-15° S; 168-173° W) is presented. The period spans that from the mid-1 9th
Century to the early 1920's, when the most recent serious work was carried out. In this
preliminary checklist a total of 198 taxa is recorded comprising 15 Cyanophyceae, 89
Rhodophyceae, 33 Phaeophyceae, and 60 Chlorophyceae. This probably represents no
more than 60 per ce:it of the actual flora based on available lists of the Fiji islands and
French Polynesia. Included in the list are 26 species for which the Samoa islands are
the type locality (13 percent of the currently known flora). A number of these species
may be endemic to the archipelago.
INTRODUCTION
Samoa is an archipelago made up of two politically distinct island groups,
located between 13-15 degrees South latitude and 168-173 degrees West longitude
(Douglas & Douglas, 1994). The two groups which include American Samoa to the
east became a part of the United States in 1899, while Western Samoa (now called
Samoa since 1997) gained independence in 1962, from New Zealand. The archipelago
consists of 17 islands, coral islets and atolls with a total land area of 3,121 sq. km.
Savai'i island (Samoa) is the biggest island, accounting for 1,820 sq. km. The
population is 50,923 in American Samoa (Douglas & Douglas, 1994) and 170,000 in
Samoa (1997 census).
The climate is tropical and consists of two distinct seasons. The dry season is
from May to September bringing very little rainfall, and the wet season from
November to March can bring tropical cyclones. The average annual rainfall is up to
7000 mm. The temperature is relatively warm with a daytime average of 30°Celsius

and nighttime averages of20-25°Celsius. The relative humidity averages 80 per cent
(Douglas & Douglas, 1994).
The flora and fauna of the archipelago were first made known to the world by
European explorers. Captain M. Dwnont d'Urville (1822-1825), a French explorer was
the first to collect and document the flora and fauna ofthe archipelago. This was
insignificant compared to the collections made by Captain Charles Wilkes of the
United States Exploring Expedition (1838-1842). The Godeffroy Expedition (1862-
1872) from the Hamburg Museum specialised in zoological studies, however, some
botanical collections were also made (Grunow, 1874; Reinecke, 1896; Kramer, 1995).
The early missionaries contributed much to the knowledge of the Samoan islands in
the early nineteenth century. Since then more and more scientists have traveled and
worked on the fauna and flora of Samoa.
History of Phycological Research in the Archipelago
Reviews of previous botanical research including the algae from Samoa may be
found in Kramer (1902-1903; 1994-1995), Reinecke (1896) and Schmidt (1928).
Further reference to the Samoan seaweeds is to be found scattered among the algal
literature from the middle ofthe last Century to the middle ofthis Century. The first
recorded algal collections frmn Samoa are in Bailey and Harvey (1862), who described
Liagora hirta from specimens collected during the United States Exploring Expedition
in 1838- 1842; no other algae from Samoa were mentioned. The first significant
collections were made by Dr Eduard Graeffe during the Godeffroy Expedition. Dr
Graeffe ' s collections, which were mainly from Upolu and Savai'i islands were studied
by Dr A. Grunow, who published the red and brown algal groups with the intention of
publishing the greens and the blue-greens later (Grunow, 1874). Much of this
collection, which was housed at the Hamburg Botanical Museum, is now presumed
either lost during the Second World War, or moved to Grunow's Herbarium at the
Natural History Museum, Vienna. Grunow reported 32 taxa ofRhodophyceae
including 3 new species, and 11 Phaeophyceae including 2 new species.
Following Grunow's (1874) work, Dr Reinecke ofBreslau, Germany, who
resided in Samoa from 1893-1895 and with assistance of many experts, published a
catalogue of most of the botanical groups from Samoa (Reinecke, 1896). The
freshwater algae were published by Scbmidle while the marine algae were published
by Reinbold, both in Reinecke (1896). Reinbold included the Cyanophyceae and
Chlorophyceae collected by Dr Graeffe that had been omitted from Grunow (1874).
Reinhold's list includes 39 Rhodophyceae, 29 Chlorophyceae, 10 Phaeophyceae and 3
Cyanophyceae. Forty-three new records for Samoa were added ofwhich 2 new species
were described. In his synopsis of Sargassum species, Grunow (1915 - 1916) included
two species from Samoa.
American Samoa remained unstudied, until the Carnegie Expedition in the
early 1920s. William Albert Setchell, an American botanist who also examined
collections made by Dr Alfred Goldsborough Mayor, Rollin T. Chamberlain, AL.
Treadwell, Siltupe and F.A. Potts, provided tnuch ofwhat is known ofthe benthic
marine algae ofAmerican Samoa (Setchell, 1924). Setchell recorded 100 taxa: 11
Cyanophyceae, 48 Rhodophyceae, 12 Phaeophyceae and 29 Chlorophyceae. Sixty-
eight new records were added for the archipelago including 14 new species. Setchell's

American Samoan collections are housed in the herbarium at the University of
California, Berkley, (UC). Setchell hired a professional collector (Harold E. Parks) to
survey the tropical Pacific but Samoa was not revisited (P.C. Silva,pers. comm.).
Following Setchell, a number ofPhycologists have since collected more algal
specimens from American Samoa. Roy Tsuda and Richard Buggeln carried out
extensive field work in Tutuila in 1963 (Tsuda, 1968). Some of their collections are
housed at UC and others are in BISH. The Polysiphonia specimens were identified and
published by Hollenberg, who included five new records for the archipelago
(Hollenberg, 1968).
In 1928, Schmidt compiled a catalogue of previously published as well as new
records of algae from 'New Guinea and Western Oceania' (Schmidt, 1928). Schmidt
relied on Grunow, Reinbold and Setchell's publications for records from Samoa, as
well as a small collection made by Captain Schneider for Heydrich in 1891 (Heydrich,
1892; Schmidt, 1928). A total of 159 taxa were included in Schmidt's list, of which 12
were new for the archipelago. Although Schmidt's (1928) publication contains some
errors and omissions, it remains an important document for the flora of the region.
A numt:,er of Samoan collections are to be found in various herbaria worldwide
and may include taxa not listed here. It is not intended here to complete an exhaustive
search ofthe literature for scattered reports of Samoan algae, although it is hoped that
these will be recorded in due course.
Arrangement of the List.
In the present work we attempt to bring together the list of benthic marine algae
previously published from the Samoan·Archipelago. The list is updated according to
current nomenclature, and follows Silva et al., (1987; 1996), unless otherwise stated.
For ease ofreference the original citations and page numbers are given for each taxon.
Genera are listed alphabetically within each family. The authorities are given
for each genus but not the full citation. Within each genus the species are arranged
alphabetically and for each entry the following are provided according to a standard
fom1at:
• Binomial;
• Nomenclatural and taxonomic synonyms wtth specific reference to Samoan
records;
• Misapplied names with specific reference to Samoan records.
Endnotes are provided either to clarify some points raised or to guide the reader to
other relevant references for further information. An asterisk (•) is used to indicate
taxa for which a type locality is from the Samoan archipelago.
A variety of taxonomic and nomenclatural uncertainties will be evident from
the list; these will not be resolved until further studies, including where necessary the
examination oforiginal specimens, have been undertaken.

Endnotes
1 Reinbold (1896: 253) reported this as a brackish water alga.
2 Schmidt (1928: 55) updated Reinhold's record of Bangia tenuissima to Erythrotrichia investiens
without providing any explanation. Verification of the Samoan materials is needed.
3 Schmidt (1928: 55) updated Setchell's record of Goniotrichium alsidii (Zanardini) M.A. Howe to G.
elegans (Chauvin) Le Jolis & Forti following Zanardini (1873: 457). The authorities he provided for G.
elegans followed those of Chauvin (1842: 33-35 'Bangia elegans') and Le Jolis & Forti in De Toni
(1924: 23).
4 According to Silva et al.• (1996: 127-128) Zanardini (1851: 36) erroneously associated Liagora with
Fucus fragilis Forsskal, in which he indicated that his specimen might be referable to F. fragilis. If the
combination is made it remains as a synonym ofActinotrichia fragilis (Forsskal) B0rgesen.
5 The original record is from Grunow (1874: 38) on collections made by Dr. Graeffe. Schmidt (1928:
57) published this record under Brachycladia marginata (Ellis & Solander) Schmitz, without any
explanation.
6 The Samoan records are tentatively placed under Tricleocarpa cylindrica (Ellis & Solander) Huisman
and Borowitzka, following Silva et al.. ( 1996: 116-1 17), who placed Grunow's Samoan record under the
mentioned name. The need for further examination of Samoan plants is vital as currently authors such as
Huisman & Borowitzka (1990: 168) retain G. fastigiata as a distinct species.
7 Schmidt (1928: 56) published Grunow's record of Galaxaura clifioni Harvey under Liagora cliftoni
(Harvey) J. Agardh, without any explanation.
8 The authorities stated by these authors are G. crinale (Turner) Lamoureux ex J. Agardh. See Silva et
al., 1996: 137 for discussion ofauthorities.
9 Setchell (1924: 164) provided a new combination for Acrocarpus delicatulus Klitzing. Schmidt (1928:
60) gave the authorities of(Ktitzing) Crouan in Maze & Schramm (1?70-1877: 200), while Payri &
N'Yeurt ( 1996: 888) adopted the authorities of (Ki.itzing) Grunow (possibly Grunow's '1867'
publication). If this is so then Grunow should take precedent over Crouan. Until this is sorted out, the
Samoan record adopts the authorities given in Setchell (1924: 164).
10 The Samoan records are those ofGrunow (1874) and Setchell (1924) in which Schmidt (1928: 65)
published under Gelidiopsis rigida possibly following Weber-van Bosse (1904: 104-105), though no
explanation was given.
11 The authorities given by Grunow (1874) and Reinbold (1896) were changed by Schmidt (1928: 63),
howeyer they still differ from those given by Silva et al., (1996: 165-167). The authorities need to be
further sorted out.
12 The authorities given by Schmidt ( 1928) differ from those ofGrunow (1874) and Reinbold (1896),
however all are different from those given by Silva et al. , (1996: 178-180, 916).
13 Corallina granifera Ellis & Solander, is a misapplied name for Haliptilon roseum (Lamarck) Garbary
& Johansen, in the Indian Ocean but ofSonder's record only (Silva et al., 1996: 233-234). Corallina
granifera from Samoa is retained as a distinct species following Schmidt (1928: 84) and Reinbold
(1907: 207), and until such a time in which the specimen is re-examined.
14 The authorities given by Schmidt (1928) differ from Silva et al., (1996). See Silva et al., 1996: 297.
15 For authorities see Silva et al., 1996: 346.
16 The Samoan record of lomentaria parvula var. tenera is placed under Champia parvula with great
reservation. This is further exacerbated with the authorities given by Grunow and Reinbold, which differ
from those in Silva et al. , (1996: 346-347). Reinbold (1896: 274) incorporated Grunow's Samoan
records of Laurencia under the genus lomentaria, thus creating confusion on the appropriate generic
placement of the Samoan specimens. Schmidt (1928) placed Lomentaria spp., as reported by Reinbold
under uncertain species in the genus laurencia.
17 Reported in error by Schmidt ( 1928: 69) probably as a result of a mix-up made by Reinbold (1896:
2~).
.
·.
18 Reported in error by Schmidt (1928: 75). Ceramium byssoideum Harvey, is a taxonomic synonym of
Ceramiumflaccidum Harvey, according to Silva et al. , (1996: 397).
19 Reported in error by Schmidt (1928 : 75). C. gracillimum is a taxonomic synonym of C. fla ccidum
according to Reinbold ( 1896: 271 ) and Silva et al., 1996: 397).
20 In establishing the genus Melanamansia R.E. Norris (1988:217) demonstrated that collection of A.
glomerata J. Agardh from Mauritius and South Africa belongs to Amansia rhodhantha (Harvey) J.
Agardh, whereas Pacific records belong to M. glomerata. He reconnnended that records for areas other

than Mauritius and South Africa be re-examined. In a recent study we have demonstrated that the genus
Amansia (sensu Norris, 1988; 1995) occurs in Samoa (South & Skelton, 1999.).
21 Authorities require further investigation. Setchell ( 1924: 160) hinted that Bostrychia vie/lardi Kutzing
is a taxonomic synonym of 8 . tene/la.
22 Schmidt ( 1928) gives Nageli ( 1846) as the second authority ofH. secunda, while Silva et al., ( 1996)
gives Ambronn (1880). Clarification of authorities is needed.
23 Records of Laurencia as reported in Grunow (1874) have been incorporated under the genus of
Lomentaria by Reinbold (1896). Schmidt (1 928) followed Grunow's list, however he list the species
recorded by Reinbold as uncertain species. See endnote 17.
24 The presence of this alga is rather doubtful due to insufficient material according to Setchell (1924:
161).
25 See Silva et al. ( 1996: 538) for discussion ofauthority.
26 See Silva et al. ( 1996: 542).
27 Reported in error by Schmidt ( 1928) based on Grunow ( 1874: 48).
28 Reported in error by Schmidt (1928) of Setchell's ( 1924) specimen.
29 See Silva et al. (1996: 556).
30 Ectocarpus amicorum was a misapplied name for Indian Ocean specimens in Jadin (1935: 158)
according to Silva et al. (1996: 568). There is a need to examined Samoan materials to verify their
fi0
; ,~~~~ commersonii is a misapplied name in Silva et al., ( 1987: 77-78), and Silva et al. (I 996: 601-
603).
32 Schmidt (1928) recognised Vickers as the second authority. According to Allender & Kraft (I983),
records of P. gymnospora from the Indo-Pacific region may be referable to their new species P.
boergensii. See Silva et al. ( 1996: 604-605) for further discussion.
33 Reinbold (1896; 1907) indicated that Grunow 's record of Cutleria pacifica might be a variety of C.
multijida.
34 Silva et al. ( 1996: 630) gave the authorities as A. c/athratus (C. Agardh) J. Agardh. Requires further
investigation.
35 It is of interest and probably highly relevant to note Noro & Abbott's (1994) discussion relating to
Grunow 's treatment of Sargassum. According to them, the large number of names of species in
Sargassum in the Pacific are names proposed by Grunow (1 9 15; 1916) on the basis of very small
numbers of specimens (some taxa have only ont: specimen). Aside from Setchell's records, other
Sargassum species reported by Schmidt (1928) and Reinbold (1907) need verification. Current
phycological research in the region will hopefully shed more light into the complexity of this
polymorphic genus. It is therefore likely that the nine taxa reported from the Samoa islands are probably
much less.
36 The synonym was proposed by Womersley & Bailey (1970: 299-300), however s ome (Tseng & Lu
Baoren, 1995: 68-69, 89, 93, 95-96, 98-101) continue to recognise S. binderi as a distinct species. See
Silva et al. (1996: 690).
37 Il.rackish water alga.
38 For .authorities see Silva et al. (1996: 767).
39 Brackish y.,ater alga.
40 Setchell's ( 1924) record of Rhizoclonium implexum was included in error as R. tortuosum by Schmidt
( 1928: 29).
41 Chaetomo,p ha tortuosa (Dillwyn) Kiitzing is an illegal name; see Silva etal.. (1996: 788, 936). The
delimitation of Rhizoc/onium and Chaetomorpha remains problematical. The placement ofReinbold's
record under Rhizoclonium tortuosum requires further investigation.
42 Possibly a fresh-water alga.
43 Reinbold expressed his uncertainty regarding this alga.
44 According to Silva et al. (1996: 768), there are no marine records for this species. Reinhold's record is
therefore in doubt.
45 There is considerable doubt regarding the presence of this alga or its validity. Schmidt (1928)
questioned Reinbold's record, while Silva et al. ( 1996: 794) stated that it is a misapplied name of
Cladophoropsis sundanensis Reinbold. The record is tentatively placed as it is, until new information
emerges to support its position.
46 There is disagreement as to whether C. peltata should be regarded as a variety of C. racemosa
(Forsskal) J. Agardh or a distinct species. See Silva et al, (1996: 829-830) for a discussion on this.
47 The occurrence of C. adherens reported in Reinbold (1896: 269) from Samoa is unlikely. Records of
C. adherens maybe referable to C. arabicum Kiitzing. See Silva et al, (1996: 851).
