This is very near S. punicea, Hemsl. The colour of the 
flower is very variable in that species (cp. Franchet, in Bull. Soc. 
Bot. France, xlili, p. 318): brown, purple, or yellowish. But 
the curious pale, watery, bluish colour of the small flowers of 
Forrest’s plant has apparently not yet been observed. Possibly, 
it may be only a form of S. punicea, Hemsl.

grassy openings in pine forests on the eastern flank of the 
Lichiang Range. Lat. 27° 25’ N. Alt. 11,000 ft. September

The typical form was collected in the same neighbourhood : 
“ coteaux de Likiang-Senchan, alt. 4000 m.”’ (Delavay, No. 2208), 
but is a much smaller plant than this fine variety.

I do not know if this interesting form will prove specifically 
different from O. Acetosella. By describing it, I want to draw the 
attention of the collectors to it. Forrest’s specimen is certainly
