The interesting Gesnerad which is here figured is a 
native of Siam, where it grows on rocks by streams on 
Mount Doi Sutep, near Chiengmai, at about 1,800 feet 
above the level of the sea. From this locality seeds were 
sent to Kew by Dr. A. F. G. Kerr in 1912; the plants 
raised from this consignment flowered in a tropical house 
in March, 1913, and provided the material from which our 
illustration has been prepared. The species had been 
already described by Mr. Craib from herbarium specimens 
communicated by Dr. Kerr from the same locality, and had 
by him been referred to the genus Streptocarpus, based by 
Lindley upon a South African plant; in spite, of the 
remarkable extension of range of the genus which this 
decision implies, it seems clear that, if a conclusion can be 
based upon essential agreement as regards floral and fruit
