though none possess such tubers as the American Gesnerias,

Lysionotus serrata is a native of the subtropical and 
temperate regions of the Himalaya, from Kumaon in the 
north-west to Bhotan in the east, inhabiting damp forests | 
at elevations of 5000 to 8000 feet in Sikkim, descending to 
2500 in Kumaon; it is also abundant at 4000 feet in the 
Khasia mountains, and is found on the Karen hills in 
Burma ; its favourite sites are mossy rocks, banks, and old 
tree-trunks. At Kew it fills a square pan with stems a foot 
high, and seems quite at home in a subtropical heat, 
flowering in July and August; and in its native mountains 
the peduncles are often a foot long, and bear clusters of forty 
to fifty flowers, of which many open at atime. The plant 
figured was raised from seed sent by our excellent corre- 
spondent in Darjeeling, Mr. Gammie, of the Forest Depart- 
ment. The pale whitish stripe along the nerves of the leaf
