The genus Piptospatha was established in 1879 by Mr. 
N. E. Brown in the Gardener’s Chronicle, upon a Bornean 
plant, P. insignis, which has been figured in this Magazine 
(Tab. 6598); the generic name taking precedence by one 
year of Engler’s Rhynchopyle. It belongs to the tribe 
Philodendree of Aroideex, and is distinguished by the 
nodding spathe, the limb of which is calyptrately deci- 
duous from the tube, the latter forming a funnel-shaped cup 
around the fruiting spadix; by the prolonged connec- 
tive of the anthers, which in P. insignis forms a conical 
horn; and by the unilocular ovaries with basilar or sub- 
basilar erect ovules. The seeds of the species in which these 
have been seen, are remarkable for the testa being produced 
into a tail longer than the nucleus. P. Ridleyi differs 
from P, insignis, in the greater size of the broader foliage, 
in the connective of the anthers forming a pubescent hemi- 
sphere, and in the orbicular stigma distinct from the crown 
of the ovary. The other described species are P. elongata, 
N. E. Br., and P. marginata, N. E. Br., both Bornean, 
and published in Engler’s “ Bot. Jahrb.,” i. (1881), 184,
