I. Thomsoni is one of the commonest sub-alpine species 
of the genus in the Western Himalaya, at elevations of 
eight thousand feet to twelve thousand feet, from Kumaon 
to the Indus River, It also occurs rarely in Sikkim, 
and no doubt inhabits the intermediate ranges of Nepal, 
though it has not hitherto been collected there. It is a 
very attractive plant, from the abundance of its rose- 
coloured flowers amongst the deep green foliage, followed 
by the red, drooping pods. 
Seeds of I. Thomsoni were received at the Royal 
Gardens, Kew, from Mr. Duthie, in 1900, plants raised 
from which flowered in the Herbaceous Ground in August 
of the same year, and continued flowering till October. 
Descr,—A perfectly glabrous, erect annual, eight to 
twelve inches high. Stem simple or sparingly branched, 
four-angled towards the top with muricate angles. 
Leaves alternate, crowded towards the top of the stem,
