The temperate and subtropical regions of the Himalaya 
Mountains, especially in the eastern division of the range, 
abound in beautiful species of Gesneraceew, of which a 
considerable number have been cultivated at Kew, and some 
figured in this work ; and it is not a little remarkable that 
the subject of the present plate, which is the most widely 
distributed and one of the most beautiful of them all, 
should have so long been a stranger to our gardens. 
Unfortunately these Gesneracee of India are all stove or 
greenhouse plants, and in the case of the latter, the wintering 
of them requires great care, as they cannot be exposed to 
the long cold of the English winter, and if put by in a 
greenhouse they are apt to start into growth too early ; 
many of them, however, and the present in particular, form 
fleshy rootstocks which will stand a good deal of drought,
