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.

 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 ; inf ructescentiis 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 cm 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

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
