4. P. Clarkei, Hook. f. ; dwarf, nearly glabrous, dioecious, leaves 

 ^-1 in. in unequal pairs oblong ovate or lanceolate obtuse or subacute 

 oblique or not sparingly serrate 3-nerved base cordate, cymes erect longer 

 than the leaves sparingly branched, sepals half the length of the minute 

 straight turgid orbicular-ovate smooth achene. 



SIKKIM HIMALAYA; at Tchonpong, alt. 5000 ft., Clarice. 



Stems 3-6 in., simple or much branched, leafy. Leaves membranous, smaller from 

 half to two- thirds the size of the larger ; petiole about half as long as the blade, 

 stipules broadly ovate obtuse. Cymes usually long-peduncled. Achene -fa in. long, 

 pale, sometimes hardly longer than the broadly ovate or narrowly oblong dorsal 

 sepal. 



C. Leaves 3-nerved, subwhorled at the top of the stem, very unequal. 



5. P. approximata, Clarke in Journ. Linn. Soc. Sot. xv. 123 ; quite 

 glabrous, dioecious, stem short naked below, leaves crowded and almost 

 whorled at the top of the stem lanceolate or elliptic-lanceolate coarsely 

 serrate 3-nerved, petioles very unequal, cymes very small on very long 

 peduncles often subglobose few-fld., achenes smooth. P. ternifolia /3.,

TEMPERATE SIKKIM HIMALAYA, alt. 7-10,000 ft., J. D. H., Clarice, Treutler. 



Stem 4-8 in. from a tuberous base, slender. Leaves 1-4 in., very variable in 

 length, lower pair sometimes distant, smaller ovate and oblong, obtuse, all the upper 

 crowded and spreading, base rounded or subcordate ; petiole | f in. ; stipules minute. 

 Peduncle of cymes much longer than the petiole; male sepals broad, shortly mu- 

 cronate ; fern, very unequal, narrow, one or more nearly as long as the minute 

 straight achene. Mr. Duthie sends from the Jumna Valley (No. 580), Kumaon, 

 young plants of what may be a form of this with ovate leaves in. long, or is perhaps

D. Leaves 3-nerved, those of each, pair subequal, quite or nearly entire. 



6. P. smilacifolia, Wedd. in Ann. Sc. Nat. Ser. 4, i. 186 ; Monogr. 

 181 ; DC. Prodr. xvi. i. 110 ; suffiruticose, quite glabrous, dioecious, branches 

 angular, leaves elliptic-lanceolate acuminate quite entire (rarely serrate at 

 the tip) 3-nerved, cymes shortly peduncled, achenes smooth. P. Goglado

EASTERN TROPICAL HIMALAYA; from Sikkim to Mishmi, alt. 2-4000 ft.

Stems 2-4 ft., very robust, woody below, many-angled, branched above. Leaves 

 3-14 in., membranous, narrowed into a petiole 1-4 in., cross-nervules strong; 

 stipules triangular or lanceolate, persistent. Cymes often in pairs, very variable iu 

 length and form, short and dense-fld., or lax and dichotomously branched ; male fl. 

 minute ; fern, sepals much shorter than the achene. Achene -^ in. long, broadly 

 obliquely ovoid. In many respects this approaches P. scripta. The names Pilea 

 smilacifolia & miconiafolia appeared iu the same year. 



7. P. lancifolia, Hook. f. ; small, herbaceous, quite glabrous, 

 dioecious, slender, leaves long-petioled subfalcately lanceolate acuminate 

 entire or sparingly serrate towards the tip 3-nerved, cymes very slender
