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} in., and the small fruits are only 
1-4 in. diam.—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. Hamiltonit and from 
P. nepalense, whence the fruit is described as ovoid. 
33. P. Lonchites, Roem. & Sch. Syst. i. Mant. 241; quite glabrous, 
branches woody terete, nodes much enlarged, leaves shortly petioled thinly 
coriaceous elliptic- or oblong-lanceolate subacute 3—5-nerved from near the 
base, peduncles longer than the petioles, male spikes 3-1 in., fruiting females 
1-2 in. flexuous, rachis tomentose, bracts orbicular. Mig. Syst. Pip. 331,

PENANG, Porter, Wallich. 
Branches rigid, internodes short. Leaves very uniform, 24-3 by 1-1} in. sub- 
acute at both ends, tip not at ‘all caudate, nervules reticulate, uppermost oblique an 
subauricled at the base; petiole }-} in. Male spikes uniformly short; bracts ciliates 
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 dicecious, rarely poly- 
gamous. Fruits forming loosely interrupted spikes usually larger than 1n 
Sect. 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 qup 
under the ovary, margins not or very slightly raised ; bracteoles forming 4 
semilunar ridge above the ovary. 
34. P. nigrum, Lina. Sp. Pl. 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.
