Punco ANponGo.—An acaulescent herb, perennial, with a tuber- 
culose yellow-flesh-coloured rhizome with strong thick fibres 13 foot 
long. Leaves hastate, long-stalked, petiole spotted with purple at the 
base, cylindrical, firm, lateral leaf-lobes, obtuse, median shortly and 
abruptly acuminate, bright green and somewhat shining above, 
glaucous-pruinose beneath ; primary veins all converging. Flowers 
apparently hypogeal. Berries whitish, angulate-subpyriform, remains 
of stigma forming an umbo, bilocular, one-seeded (one loculus being 
generally empty), closely crowded into a shortly-stalked underground 
head. Here and there in thickets with short herbage near the stream 
between Quilange and Catete on the presidium, One specimen with 
unripe fruit, the rest barren; Feb. 1857. No. 281. 
Probably a distinct species ; but, as the material is limited to a single 
plant with leaf but no flower or fruit, it is impossible to be more 
precise.
