marginalis, secundus submarginalis, intimus a margine non valde (V4— Va 

 latitudinis semifaciei laminae) remotus. Pedunculus quam petiolus foliorum 

 certe duplo longior, h 3'/2cm. longiis. Spatha oblonga vel ovato-lanceolata, 

 _|_ 21/2— 3V2 ^ 1 — IV2 cm., acuminata, breviter angusteque apiculata. Spadix 

 subsessilis, cylindricus, quam spatha brevior, ± 2 cm. longus et 2 mm 

 crassus; ovaria breviter prismatica, supra applanata; stigma minutum, 

 discoideum. 



AU. 2000 m. — Near P. sumatranus Engl. which differs in having the 

 pétiole longer-sheathed, and the lamina provided with 2 collective veins 

 of which the inner one is remote from the margin.

o Pothos sumatranus, MiQ. fnot Enql.), Sumatra, etc., 596. 



Enqler referred this species doubtfully to P. inaequilaterus Engl. 

 — The Buitenzorg Herbarium possesses the stérile material gathered by 

 Teysmann in Sumatra (Lubu-alang) on which Miquel based his diagnosis; 

 it differs from P. inaequilaterus in having the pétioles much longer, to 4 

 times as long, sheathed nearly or quite to the knee and in having the 

 lamina much less unequal-sided, the broadest side being at best l'/i X as 

 broad as the narrowest side. Consequently both species are not identical 

 and as long as the identicity with another valid species cannot be made 

 ont because of the absence of fertile material. the name P. sumatranus 

 Miq. should not be suppressed and P. sumatranus EngL renamed. — 1 

 propose to call the latter:

I believe Merrill's information in „The Interprétation of Rumphius's 

 Herbarium Amboinense" is correct and, althou:.Th the species has not yet 

 been recoveied, I think it to be a vaiid one which, according to Rumphius' 

 plate, is a species belonging to the group of Engler's Longivaginati and 

 by its stalked spadix nearly allied to P. Wallichii Hk. / —As long as the 

 identicity with another valid species cannot be made out the name P. 

 latifolius L. should be maintained and P. tatifolius Hk. f. renamed. — I 

 propose to call the latter:
