Though the material is imperfect, this seems to be a distinct species, 
differing from P. campylotropa in the delicate membranous leaves and the 
stalked anthers. 
P. bracteata, A. W. Hill, sp. nov. (PI. XV, Fig. 15). 
Tuber hypogaeum, orbiculare, circa *8-1*2 cm. diametro, apice radicibus 
fibrosis instructum. Caulis subnullus. Folia viridia, in rosulam congesta ; 
petiolus 8-to cm. longus ; lamina rhomboideo-orbicularis vel orbicularis, 
apice saepius paullo obtusa, 2-3 cm. diametro, fere e medio peltata, 
magis minusve membranacea, venis 8-9 conspicuis. Amenta 5-20 cm. 
longa, inferne laxiflora, pedunculis circa 10 cm. Iongis. Bractea viridis, 
magis minusve orbicularis, circa 1*5 mm. diametro; stamina filamentis 
instructa. Bacca globoso-fusiformis, 1*5 mm. longa, -95 mm. lata, verrucosa, 
fulva, apice stylo cylindrico-conico praedita. Semen ellipticum, circa 1 mm. 
longum, *8 mm. latum. 
1 This specimen probably belongs to this species, but the material is insufficient for a complete 
determination.
