532 OXXXVL URTICACEE. (J. D. Hooker.) [ Pilea. 
troduced into India, and will no doubt soon be ubiquitous there. It occurs under 
two forms, as a creeping weed with very minute petioled elliptic or orbicular leaves 
3g in. broad, in the streets of Calcutta (Harrington St., Clarke); and in a more erect 
form with spathulate leaves } in. long, on damp walls at Hoogly (Levinge), at Dacea, 
and in Perak (Kunstler), lt has been found also in Ceylon. It is a penninerved 
entire-leaved species, but the nerves are very obscure. 
A. Leaves penninerved throughout. -Achenes smooth. 
1. P. ternifolia, Wedd. Monogr. 202; DC. Prodr. xvi. i. 124; quite 
glabrous, stem erect usually simple, leaves opposite and ternately whorled 
subsessile linear or linear-oblong more or less coarsely serrate, cymes short 
lax or dense-fld., peduncles longer than the petioles, achenes minute oblong- 
ovate smooth. 
SrkxiM HIMALAYA, alt. 6-8000 ft., Griffith, &c. (Kew Distrib. 4520). 
Stem 10-18 in. from a thickened base, smooth, slender, rarely branched. Leaves 
23-33 by 4—4 in., flaccid, base obliquely cordate, subglaucous beneath; nerves very 
many, close set; petiole 4!; in. ; stipules obscure. Cymes sometimes half as long as 
the leaves very slender and sparingly branched, at others short rounded or with 
spreading branches. Flowers and achenes very minute.—In the absence of the 
3 nerves, this species suddenly departs from the typical condition of its near allies. 
“The incurved sepals eject the achene with elastic force ” (Clarke). 
B. Leaves 3-nerved, those of each pair unequal. Achenes smooth.

suffruticose, dicecious, shoots petioles and peduncles more or less furfurous'y 
tomentose, leaves 3-nerved in unequal pairs, larger petioled obliquely oblong
