THE PHILIPPINE SPECIES OF PANDANUS. 
By Count Ugolino Martelli, 
{Florence^ Italy,) 
Father Manuel Bianco^ in tlie iirsi edilitm of his "Flora de Filipinas'* 
(1837) J describes only five species of Pandaniis^ P. spiralis, P. gracilis, 
P. exaltattis, P. Sdbotan, and P. radicansj and in the second edition 
(1845) he adds two others, P. vialatensis and P. inermis. No further 
contribution to the genus appeared in the edition of 1879, published by 
r 
Naves and Feiiiandez-Villar.^ 
Yidal in his "Floi*a forestal de Filipiuas, Sinopsis de faniilias y 
gencros" (atlas) (1883) tab. 95, represented as Pandanus udoralisaiuias 
L. (=-P. tectorial Sol.) a quite different species^ which I have nauic\I 
Pandaniu^ Vidalii. iVnother Pandanus mentioned by Vidal in his "Re- 
vision de Plantas vasculares de Filipinas" (188G), 'ZSQ, Yidal 19JfO, 
collected at "S. Mateo^ Provincia de Manila," I have not been able to 
identify. AVarburg^ in his recent monograph of the family credits to the 
Archipelago but one definitely known species of the genus, P. tectoritis 
Sol., reducing to it P. spiralis Blanco, and considering Blanco's other 
species as doubtful or imperfectly known. These were the few species 
of Pandanus known from the l*hilippines up to the year 1004, and 
from the above enumeration one might suppose that the genus was not 
richly represented in the Archipelago. However in 190:^ botanical in- 
vestigations were commenced under the auspices of the American Govern- 
ment, and since that time very many new plants have been discovered, 
among them a considerable number of previously described Pandanacem 
not before known to exist in the Archipelago, and others completely new 
to science. Mr. A. Lolier and Mr. A. D. E. Elmer have also contributed 
materially to our knowledge of the rhili]>pine flora and have given 
especial attention to the representatives of the genns Pandanm. Since 
^ Tn the "Novisslnia Appendix" to Blanco's "Flora de Filipinas," on pajre 284, 
Naves enumerates, as Philippine, seventeen species of Fandanus. \nii T nm very 
sceptical regarding their correct determination, as well as regarding their 
occurrence in the Philippines. As the names of these species are not accompanied 
by any description, and no licrbariuni specimens are extant, I do not consider it 
worth while to consider them here.
