3. Clematis zemnensis W. W. Smith sy. nov. 
Species C. puhemla Hi. & T. aflSnis sed foMis bipinnatis vel biterna- 
tis, fioribns stricte umbellatis et praelonge pedicellatis, filamentis latis 
perbrevibus distinguitur.

6“8 c.m. lata, bipinnata vel biternata, segmentis 2-3-5 c.m.x 1-1*5 cm. 
ovatis vel ovato-lanceolatis, acute iobatis vel serratis, subapiculatis, 
pubescentia vel subglabra ; petiolus ad 3 cm. Injiorescentia axillaris ; 
pedunculus praslongus ad 10 cm. pubescens ; supra in 2-7 pedicellos 
stricte et umbellate divisus ; pedicelli ad 7 cm. longi duabus linearibus 
bracteis (*5 cm.). Sepala 1*5 cm. X -5 cm., patentia, oblongo-lanceolata,

Zemu Valley, 9,000 ft.. No. 2671. Only the one shrub seen. 
3, Clematis Buckanaiiiana DC. 
Llonakh, 11,000 ft., No. 1735, 
2. Tlialictrnm Linn.

Zemu, Llonakh, and Thango, 10-13,500 ft., Nos. 1221, 1757, 2471, 
2675. Common. 
Sub-sp. tsangense Briihl. 
Upper Llonakh, 16,500 ft.. No. 2,311. Sparingly. A Tibetan 
plant, recorded previously from the neighbourkood of Khambajong. If 
T, platy carp urn H.f. & T. be an alpine state of T. cultratum Wall, the 
above sub-species would be a still more reduced form. There are, 
however, as Briihl points out, (Ann. Roy. Bot. Card. Calc. Vol. V, p. 72) 
considerable differences in the ripe fruit.
