Primula strumosa in Tibet

From the archive record

The yellow flowered species, P. strumosa was described from plants found at Champa Pumthang in Bhutan and it was associated with P. elongata which it distinguished in having a long seed capsule opening by valves. P. calderiana and P. strumosa are very similar in their characteristics but differ in flower color, and perhaps scent (this is very subjective) and in their geographical ranges, with P. calderiana distributed in the Eastern part of the Himalayas and P. strumosa distributed to the West. These two species rarely meet, but when they do, hybridization occurs, giving a range of muddy colors. Primula strumosa is part of a complex of similar yellow flowered species which also includes: P. hillaris, P. jucunda, P. tanneri, P. tsariensis, P. elongata and P. barnardoana. Considered by John
