The séparation of Se. cuscuaria PR. and Se. marantifolius MlQ. in my 

 previous paper on Malayan Araceae, quoted above, was based on a com- 

 parison of the plants of the Buitenzorg Herbarium, determined several years 

 ago by Engler as Se. cuscuaria. 



Another plant, recently gathered in Java [Preanger Regencies, R. C. 

 BAKHUIZEN VAN DEN BRINK No. 3067), has given me cause to a new 

 comparison and now 1 am inclined to consider ail the Javanese plants 

 determined as Se. cuscuaria as really distinct from our single Amboiiiese 

 one which may represent the typical form of Se. cuscuariia PR. 



The said Amboinese spécimen (BOERLAGE No. 514, not574as is men- 

 tioned in Engler's monograph) consists of 1 small and 2 large leaves besides 

 a fructiferous spadix and is distinguished from my previous diagnosis quoted 

 above as follows : Leaves with the pétiole to 40 cm. long, the sheath 

 coriaceous, persistent ; lamina chartaceous, relatively thin, ovate, about 

 2Xas long as broad (20 — 40X11—21 cm.), broadest at about '/g above 

 the base, the base obliquely, broadly rounded ; costa beneath more or les
