 Hallier's No. 1356 {fi. subtriangularis, ENGL., var. major), mtnïioned 



in Engler's monograph quoted above, differs from the diagnosis given in 



having the pétiole 10—25 cm. long, sheathing '/s ^o nearly '/2 J^s length, 



the lamina 10—20 X 5— 7'/2 cm., triangular-subhastate 

 to -subsagittate ; the staminodes, wich are very caducous 

 and only obtectable in very young material, hâve 

 the filiform basai portion shorter, the much thickened 

 apical portion consequently larger, globosetoobconical- 

 clavate; the stamens hâve the anthers not close the 

 apex of the connective but close to the base, v^ith 

 a more or less narrow nudate space between their 

 apex and the apex of the connective (fig. w.). 

 Hallier's No. 13Q1 (//. siibtriangiilaris, EnGL.), not mentioned 



by Engler, is a smaller form of this, approaching H. paludosa Hk. F. — 



A spécimen from Java (Biiitenzorg, TJampea, Pa- 



Idan), cultivated in the Buitenzorg Gardens, differs 



in having the lamina commonly truly sagittate, 



sometimes subhastate, rarely triangular-cordate, mostly 



twice as long as broad, sometimes proportionally 



shorter and broader, with the thecae separated from 



the apex of the connective by a broad nudate space.

A spécimen gathered in Java {Mt. Tjipoetih, near Buitenzorg) by 

 R. C. Bakhuizen van DEN Brink, is distinguished in having the leaves 

 with pétiole to 80 cm. long, the lamina to 45 X 30 cm., and the peduncle 

 to 20 cm. long. 



Homalomena Raapii, ENGL., Pflzrch, LV (IV, 23 Da), Arac.-Philod- 

 Homal.-Schism., 73, fig. 4Q. 



RaaP's No. 235, occurring in the Buitenzorg Herbarium, on which 

 Engler based his original diagnosis, has the staminodes very thick-obconical- 

 clavate on a slender stalk not much longer than the apical portion. — ENGLER 

 says and draws „Staminodia filiformia. apice paullum incrassata", but in 

 reality the apex of the staminodes is so much thickened that, when seen 

 under the lens by 60 times magnifying power, it rivais the dimensions of 

 a billiard-ball crowning a darning-needle.
