PACIFIC SCIENCE, VoL XVII, January 1963 
lateral view of a phalange, nothing more. Since 
the genus existed, this was valid publication. 
Brongniart reviewed the Pandanus specimens 
collected by Gaudichaud and documented them 
as far as possible (Ann. Sci. Nat. Bot. VI, 1: 290, 
1875). For this species he postulated that it 
came from He de la Reunion. However, in the 
recent detailed revision of the Mascarene species 
(Linn. Soc. Lond. Bot. Jour. 55: 1-32, 1953) 
Vaughan and Wiehe found no local species to 
match it. 
It is of interest, then, to note that the recent 
collection from Singapore, Posher g 36,919, is a 
perfect match for Gaudichaud’s illustration of 
P. Boryi . This collection consists of one phalange 
and one leaf minus the tip, so it is scarcely more 
adequate than the Gaudichaud collection. Since 
it is a perfect match for the Gaudichaud figure, 
we offer here a description of this phalange and 
leaf^as a standard description to supplement the 
minimal publication by Gaudichaud. In the 
Singapore herbarium there are also two collec- 
tions from Singapore that fall into this same 
■species. One has six phalanges and two' leaves 
minus the tips; the other had a branch, many 
leaf bases, peduncle, core of the syncarp, and 
eight phalanges. Together they contribute to our 
knowledge of the population. No one of them 
furnishes all the details, but of all, the Fosberg 
36,919 seems best to take as a standard. 
The vessel "La Bonite,” on which Charles 
Gaudichaud was the botanist, circumnavigated 
the globe in 1836 and 1837, and stopped at 
Singapore. Pandanus is still fairly common on 
Singapore Island and occurs there in several spe- 
cies. One of the tidal estuaries not far from the 
harbor is Sungei Pandan, and the general ver- 
nacular name of the genus in Malayan is "pan- 
dan.” This was the source of our generic name, 
Pandanus, latinized and first published by Rum- 
phius, later adopted and made valid by Stickman.
