it is difficult without the fruit to distinguish this from P. nepalense ; the leaves are 

 never so large, not exceeding 5 in., and are narrower with much longer often falcately 

 curved points. The spikes are never more than 1| iu., and the small fruits are only 

 s~6 i"- diara. 1 find no specimen of this in Wallich's Herbarium, but good ones 

 in Herb. Hook, received from him. I have retained the name of khasianum, though 

 the description in the Prodromus is drawn up in part from P. Hamiltonii and from 

 P. nepalense, whence the fruit is described as ovoid.

PENANG, Porter, Wallich. 



Branches rigid, internodes short. Leaves very uniform, 2^-3 by 1-1 in., sub- 

 acute at both ends, tip not at [all caudate, nervules reticulate, uppermost oblique and 

 subauricled at the base ; petiole - | in.. Male spikes uniformly short; bracts ciliate ; 

 female much longer. Fruits unripe, sessile, ovoid. A very distinct species, the 

 authorship of which is attributed in the Prodromus to Miquel, and no allusion made to 

 Roemer and Schultes, who profess to have described from Wallich's No. 6644 B, 

 quoting " P. lanceolatum Roxb." which is inscribed on one of Wallich's tickets. As, 

 however, there are 3 species on the sheet of 6644 B," it is doubtful to which Roemer 

 and Schultes refer. 



Sect. V. Eupiper. Spikes solitary ; flowers dioscious, rarely poly- 



fimous. Fruits forming loosely interrupted spikes usually larger than in 

 ect. Chavica ; fruits and stigmas sessile. Bracts and bracteoles either 

 wholly adnate to the rachis or with raised membranous margins. 



* Bracts of the female spike forming (when dry) a short hemispheric cup 

 under the ovary, margins not or very slightly raised ; bracteoles forming a 

 semilunar ridge above the ovary. 



34. P. nig rum, Linn. Sp. PI. 28; quite glabrous, stem stout climbing 

 and rooting terete, leaves petioled coriaceous usually broadly ovate oblong 

 or nearly orbicular base usually rounded and oblique 5-9-nerved above the 

 base, nerves strong alternate, peduncles longer or shorter than the petioles, 

 flowers often polygamous, bracts of female short cupular wholly adnate 

 without raised margins, fruit globose. Vahl Enum. i. 329; Roxb. Fl. Ind.
