A very distinct little plant of tenuous texture when dried. 
Although several other Asiatic species agree with it in its 
peculiar character of a marked verticel of leaves about midway 
on the stem, with or without other leaves above or below (e.g. 
S. Stapfi, Hamet, S. pseudostapfii, Praeger (supra p. 91), 
Levit, Hamet, S. Bonnafousi, Hamet) none of these have any af- 
finity with it, and it is difficult to suggest to what species or group 
of species it is most nearly related. The broad entire opposite 
stalked leaves, long filiform pedicels, and small white flowers 
suggest the section Cepaea, but the perennial duration and es- 
pecially the very few-flowered inflorescences will not fit that 
group. Barren stems are apparently absent, annual flowering 
stems arising from the lowest leaf-axils of the previous year’s 
stems, as in S. Alfredi and some of the Mexican species. All 
its characters of root, leaf and stem point to its being a plant of 
damp shady places, as is borne out by the label. Named from 
its recalling in appearance Trientalis europaea, Linn. 
S. trifidum, Wallich.

These all represent the same plant or plants which M. Fionnét 
(supra v, 119) named S. trifidum, vars. Balfouri and Forresti, 
but later (supra viii, 140, 142) placed as varieties of S. lincari- 
folium, Royle. He ded not state his reasons for this change of 
species, and the varieties are based mainly on the shape of the 
sepals. In the Himalayan trifidum the sepals are very incon- 
stant in shape, varying from small triangular 1/, as long as the - 
petals to long, linear, equalling the petals; the sepals of trifidum
