Assrnecr<br />

Three new species, Licuala cabalionii, Calamus<br />

aanuatuensis and Cyphosperma aoutmelense, are<br />

described from <strong>Vanuatu</strong> as a precursor to a revision<br />

<strong>of</strong> the palm flora.<br />

<strong>Vanuatu</strong> (formerly the <strong>New</strong> Hebrides)<br />

is an archipelago <strong>of</strong> about 80 small to<br />

moderate-sized volcanic and coral-based<br />

islands orientated linearly north-west to<br />

south-east between l3oS and 22oS and<br />

l65oE and 170"E in the southwest Pacific<br />

Ocean. The closest neighboring land mass<br />

(I6,L92 sq km) is la Grande Terre <strong>of</strong> <strong>New</strong><br />

Caledonia, which is about 500 km to the<br />

southwest. The scattered southern islands<br />

<strong>of</strong> the Solomon Islands, <strong>of</strong> which San Cristobal<br />

is the largest at 4,200 sq km, are<br />

about 600 km to the north while the Fiji<br />

Islands lie some 1,200 km to the east.<br />

Espiritu Santo, at 4,100 sq km, is the<br />

largest island in <strong>Vanuatu</strong>.<br />

Geologically much <strong>of</strong> <strong>Vanuatu</strong> is <strong>of</strong><br />

recent (Eocene and younger) age when<br />

compared with nearby terrains; both <strong>New</strong><br />

Caledonia and Fiji retain evidence <strong>of</strong> continental<br />

(Cretaceous) formation dating from<br />

the break-up <strong>of</strong> the continent <strong>of</strong> Gondwana.<br />

There are six active volcanoes and<br />

many semi-active areas within the <strong>Vanuatu</strong><br />

archipelago. Island-building is presently<br />

taking place because <strong>of</strong> uplift wrought by<br />

the convergence <strong>of</strong> tectonic plates.<br />

The flora <strong>of</strong> <strong>Vanuatu</strong>, in essence an<br />

extension <strong>of</strong> the floras <strong>of</strong> Malesia and <strong>New</strong><br />

Guinea, is not as well known as those <strong>of</strong><br />

some nearby island groups (e.g., Fiji and<br />

<strong>New</strong> Caledonia), as many <strong>of</strong> the remote<br />

and outlying islands (most <strong>of</strong> which harbor<br />

complex forests) have yet to be thoroughly<br />

botanized. P. S. Green (I979), while writing<br />

on the findings <strong>of</strong> the I97l Royal<br />

<strong>Society</strong> Expedition to <strong>Vanuatu</strong>, noted an<br />

unexpectedly large number <strong>of</strong> plant species<br />

which were recorded for the first time<br />

in <strong>Vanuatu</strong>, particularly species from the<br />

Solomon Islands, <strong>New</strong> Caledonia, and Fiji.<br />

Of those regional affinities which have been<br />

ascertained, that with the Fiji Islands (even<br />

though they are considerably farther away<br />

than either <strong>New</strong> Caledonia or the southern<br />

Solomon Islands) is the most obvious<br />

(Schmid 1966).<br />

The affinity <strong>of</strong> the palm flora displays<br />

the same trends as does the flora in general<br />

(i.e., in a broad sense an extension <strong>of</strong> the<br />

Malesian and <strong>New</strong> Guinea floras and in a<br />

regional perspective having a close relationship<br />

with that <strong>of</strong> the Fiji Islands)<br />

(Schmid 1966, Chew Wee-Lek 1984,<br />

Dowe l99I), although in the northern<br />

islands, such as the Torres and Banks<br />

Croups, a shared distribution andlor close<br />

relationship with palm species from the<br />

southern Solomon Islands exists (the Santa<br />

Cruz Group <strong>of</strong> the Solomon Islands is geologically<br />

similar to the northern islands <strong>of</strong><br />

<strong>Vanuatu</strong>). An appraisal <strong>of</strong> the relationship<br />

between the <strong>Vanuatu</strong> and Fijian palm floras<br />

(Dowe l99l) recognizes that, despite<br />

there being only one shared species (i.e.,<br />

Cocos nucifera), rhe number <strong>of</strong> shared<br />

genera is relatively high, being in the order<br />

<strong>of</strong> seven <strong>of</strong> a total o{ fifteen. This is significant<br />

when it is considered that many<br />

palm genera which occur in the southwest<br />

Pacific are monotypic or have only a few<br />

species and that Fiji is a considerable distance<br />

away. Compare this to the number<br />

<strong>of</strong> palm genera shared with <strong>Vanuatu</strong>'s clos-

I. Juvenile plant <strong>of</strong> Licuala cabalionii with the obvious symmetrical segmentation <strong>of</strong> the leaf.<br />

est neighbor, <strong>New</strong> Caledonia; only two genera<br />

(Cocos and Cyphosperma) <strong>of</strong> a combined<br />

total <strong>of</strong> 25 genera occur in both<br />

areas. Whether Vanualu was or is in a<br />

favored position to receive propagules from<br />

Fiji (i.e., abutting prevailing ocean currents,<br />

in the paths <strong>of</strong> migrational birds,<br />

etc.) has yet to be investigated, although<br />

the uniformity <strong>of</strong> the strand vegetation <strong>of</strong><br />

the region is evidence <strong>of</strong> ocean currents<br />

being a major influence on the distribution<br />

<strong>of</strong> plants in the southwestern Pacific (Gunn<br />

and Dennis 1976, Merrill l98l). Of the<br />

eight genera which are not shared, four<br />

are monotypic, three <strong>of</strong> which are endemic<br />

to Fiji.<br />

Asia to <strong>New</strong> Guinea, northern Australia,<br />

Solomon Islands and <strong>Vanuatu</strong>. The genus<br />

has developed its greatest diversity in Malay<br />

Peninsula and Borneo (about 50 species)<br />

and <strong>New</strong> Guinea (about 36 species)' Iicuala,<br />

was not recognized as occurring in<br />

<strong>Vanuatu</strong> until I970, when I. grand'is was<br />

collected from southern Espiritu Santo<br />

(Whitmore 1973). Erroneously this species<br />

had been documented in numerous<br />

publications as originating from <strong>New</strong> Britain,<br />

an island to the east <strong>of</strong> <strong>New</strong> Guinea,<br />

an error most probably originating from<br />

its initial description from a horticultural<br />

source.<br />

Licuala cabalionii is distinguished from<br />

the closest occurring species, L. grandis<br />

H. Wendl. ex Linden (distributed throughout<br />

much <strong>of</strong> <strong>Vanuatu</strong> as well as the Santa<br />

Cruz Group and San Cristobal Island <strong>of</strong><br />

the Solomon Islands) by its divided leafblade,<br />

less spiny petiole, shorter floral pedicel<br />

and sparingly as opposed to multi<br />

ribbed endocarp. L. lauterbachii Darnmer<br />

& K. Schum. (Solomon Islands and <strong>New</strong><br />

Guinea) differs in having a short and erect<br />

inflorescence, red fruit' and irregularly<br />

divided leaf-blade.<br />

The known populations <strong>of</strong> L. cabalionii<br />

do not occur close to populations <strong>of</strong> Z.<br />

grandis although they occupy similar habitats.<br />

The former occurs in very dense<br />

colonies (almost monospecific) in primary<br />

rainforest; the forest floor in the vicinity<br />

is thickly cover with seedlings and small<br />

plants. I. grandis is much less gregarious,<br />

with very few seedlings being observed and<br />

individuals being relatively widely spaced.<br />

L. grandis is more commonly found in<br />

disturbed or secondary forest. No traditional<br />

uses or vernacular names have been<br />

recorded for L. cabaLionii.<br />

Licuala cabalionii has appeared as the<br />

manuscript names "Licuala sp. Vanua<br />

Lava" (Dowe 1989a) and "Licuala sP."<br />

preserved at NOU and BH. The sample<br />

at NOU consists <strong>of</strong> five sheets <strong>of</strong> which<br />

Discussion. Cyphosperma aoutmelen'<br />

se is most closely related to C. balansae<br />

from <strong>New</strong> Caledonia, from which it differs<br />

by its much smaller inflorescence, brown,<br />

scaly inflorescence branches, rounded and<br />

not prominent inflorescence branch bracts<br />

and smaller fruit. The two Fijian species<br />

are more distinct: C. tanga H. E. Moore<br />

has undivided or only apically divided leaves<br />

and a sparsely branched inflorescence while<br />

C. trichospadir (Burret) H. E. Moore has<br />

a distinct crownshaft, an infrafoliar inflorescence,<br />

and large fruit to 2 cm long.<br />
