from P. stipulosd, the persistent stipules and minute achene from P. Si/mmeria. I 

 suspect that Weddell's P. oxyodon is this ; there is nothing in his description to 

 distinguish it except its being perfectly glabrous. He describes P. Qracteosa as having 

 large or small serratures to the leaf, and there are Sikkim specimens of a plant alto- 

 gether resembling bracteosa except in having smaller broader deeply serrate leaves, 

 and which hence looks very different, and may be so. 



13. P. umbrosa, Wedd. in Ann. Sc. Nat. Ser. 4, i. 187, and Monogr. 

 Urtic. 243, and in DC. Prodr. xvi. i. 133; more or less pubescent or tomen- 

 tose, leaves 2-5 in. broadly elliptic-ovate or oblong acute acuminate or 

 subcaudate coarsely crenate-toothed or serrate 3-nerved base cordate or 

 rounded rarely acute, stipules subpersistent large, peduncles longer or 

 shorter than the petioles, dorsal fern, sepal much the longest, achenes 

 minute flattened nearly smooth with often a raised intramargtnal ridge.

TEMPKRATE HIM ALAYA, alt. 4-9000 ft., from Kashmir eastwards. KHASIA MTS., 

 alt. 4-6000 ft., Griffith, &c. 



Usually a tall robust monoecious or dioecious species, often densely clothed with 

 flexuous cellular hairs. Leaves broad, rather broadly toothed, with numerous rather 

 distant straight or arched cross-nervules ; petiole 1-3 [in. ; stipules membranous. 

 Cumes very various, sometimes 2-4 in. long and broad ; peduncles 1-3 in., rarely 0. 

 Malefl. small, sepals usually without spurs. Achenes ^ in., pale, straight. 



** Achenes granular or tuber culate or with a strong intramarginal 

 ridge (or smooth in Hookeriana, see also P. umbrosa). 



14. P. scripta, Wedd. Monogr. 222; DC. Prodr._xvi. i. 127; quite 

 glabrous, leaves 3-10 in. elliptic-lanceolate (rarely. broad) caudate-acuminate 

 denticulate or serrulate teeth always small and shallow, cross-nervules very 

 many slender, base acute or narrowed and rounded rarely notched, stipules 

 short, peduncles long or short, male fl. minute, fern, sepals broad dorsal 

 longest, achenes minute granulate within the intramarginal ridge. Slums

TEMPERATE HIMALAYA; Dalhousie, alt. 6000 ft., Clarke. NEPAL, Wallich 

 Sikkim, alt. 3500-6000 ft., abundant ; Bhotan and Mishmi Mts., Griffith. KHASIA 

 MTS., alt. 4-5000 ft. MTJNNIPORE, alt. 4000 ft., Clarke. 



A tall branched glabrous large-leaved species, the best characters for which are 

 the usually elliptic leaves with numerous transverse nervules and very small teeth, 

 the small male flowers without spurs on the sepals, and the minute strongly granulate 

 bordered achenes -^ in. long. Small obtuse-based leaves are, however, common. The 

 size and form of the cyme and length of its peduncle afford no characters. Munnipore 

 specimens have very large leaves 10 by 4^ in. The Dalhousie one is in very imperfect 

 flower, ai^l hence perhaps doubtful, but the leaves are characteristic. The Munnipore 

 and some of the lower level Sikkim and Khasian specimens have more fascicled greener 

 achenes. The Mishmi plant has broadly elliptic and even orbicular leaves, and 

 stouter warted (by disease ?) stems ; though quite glabrous, ib has been named P. 

 umbrosa by WcfldelL Some of Wallich's Nepal and other country specimens have 

 interrupted thickened nervules, but this is a very inconstant character; they are 

 sometimes prominent on the upper leaf surfaces. 



A very- large monrccious form (or different species) occurs at low elevations in 

 Sikkim (Mongpo, 4000 ft., Clarice), with stem as thick as the little finger, and the 

 typical leaves of scripta, but very long (4-7 in.) and slender alternately branched male 

 cymes ; the branches again divided, with scattered male flowers, all four sepals of
