PuNGO Andongo. — An acaulescent herb, perennial, with a tuber- 

 culosa yellow- flesh-coloured rhizome with strong thick fibres 1^ 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 hypogseal. 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 prsesidium. One specimen with 

 nnripe fruit, the rest barren ; Feb. 1857. No. 231. 



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.
