is an interesting Australian type, the genus being confined to 
Australia with the exception of the Javan C. javanicus Boerl. 
& Koord., which is now also recorded from Luzon. Another 
interesting Australian type, previously known only from Aus- 
tralia and Formosa, is Ipomoea polymorpha Roem. & Schultes, 
now recorded from two localities in northern Luzon.

PANDANUS PANAYENSIS sp. nov. § Vinsonia. 
Erectus, circiter 5 m altus; foliis crassissime coriaceis, rigi- 
dis, circiter 2.5 m longis, 7 cm latis, basi leviter inflatis et 11 
cm latis, apice angustatis, vix acuminatis, margine, basi et apice 
exceptis, dentibus rigidis armatis; infructescentiis pendulis, syn- 
carpiis 4, ellipsoideis ad oblongis, racemose dispositis, 12 ad 20 
cm longis, 8 ad 10 cm diametro; drupis numerosis, $ superioribus 
liberis, utrinque subaequaliter angustatis, obscure 5-angulatis, 
- circiter 4 cm longis, 5- ad 10-locellatis, apice truncatis, 5 ad 
8 mm diametro, inter loculis leviter sulcatis; stigmatibus planis, 
subreniformibus, circiter 1.5 mm diametro. 
Erect, about 5 m high. Leaves very thickly coriaceous, rigid, 
about 2.5 m long, the base slightly inflated, about 11 em wide, 
soon narrowed to about 7 cm and about this width for most 
of their length, apex narrowed, scarcely acuminate, the apical 
and basal margins unarmed, the margins otherwise with distinct, 
sharp, rigid teeth which gradually decrease in size upward, the 
midrib on the lower surface armed with short scattered teeth 
in the median and upper parts. Infructescences peduncled, pen- 
dulous, their peduncles up to 40 cm in length, 3-angled, about 
1.5 cm in diameter. Syncarps 4, ellipsoid to oblong, 12 to 20 
cm long, 8 to 10 cm in diameter, the peduncles of the lateral 
ones stout, very short, of the terminal one up to 8 cm in length. 
Drupes very numerous, the upper one-half free, subequally nar- 
rowed to both base and apex, about 4 cm long, 1.5 to 2 cm in 
diameter, somewhat 5-angled, usually 5- to 10-celled, the apex 
truncate, 5 to 8 mm in diameter, slightly sulcate between the 
loculi, the sulci about 1 mm deep. Stigmas plane, orbicular to 
somewhat reniform, about 1.5 mm in diameter.

This species resembles Pandanus philippinensis Merr., from 
which it is distinguished especially by its differently shaped 
syncarps, the drupes of which are free in the upper one-half
