 leafless thread-like siirculi which terminate in rooting buds. Stem leaves entire, 

 narrow.

Alpine Himalaya, from KASHMIR and KUMAON, alt. 13,500-17,000 ft., common, 

 to SIKKIM, alt. 18,000 ft., Lama Kongra, J. D. H. DISTRIB. North Asia, Arctic 

 regions and Rocky Mountains. 



Stems pubescent upwards. Sepals oblong, pubescent, slightly adnate and erect 

 in fruit. Petals often with red lines (not dots) near the base. Styles short. Seeds 

 ellipsoid, smooth, testa reticulate and microscopically punctulate. This species is 

 called polymorphic, but without very good reason, the following three varieties being 

 distinguished by trivial characters only, and running into each other. The Rocky 

 Mountain var. setigera (sp. of Pursh) is more remote by the calyx much adnate to the 

 fruit. 



VAR. 1. typica; leaves pubescent, margins a little ciliate. 



VAR. 2. mucronulata (Royle sp.) ; leaf margins more ciliate or glistening and 

 subspinulose. 



VAR. 3. stenophylla (Royle sp.) ; lower leaves and stem less pubescent or nearly 

 glabrous. 



SECT. VIII. Porphyrion. Leaves sub-opposite, small, often with a pore 

 at the apex. Flowers solitary, red or purple. 



32. S. oppositifolia, Linn. ; DC. Prodr. iv. 17 ; rosulate leaves ~ in. 

 obovate glabrous or the upper ciliolate, no disc surrounding the carpels. Engl.
