AN ENCYCLOPADIA OF HORTICULTURE. 
DAUBENYA (named after Dr. Charles Daubeny, a 
former Professor of Botany, at Oxford). ORD. Liliaceae. 
A genus of pretty and curious little greenhouse bulbs, 
producing their flowers in very shortly-stalked, densely- 
flowered umbels, larger than a crown piece. There are 
three species, natives of the Cape of Good Hope; at 
present, they probably do not exist in British gardens. 
They thrive in a soil composed of sandy loam and peat. 
Increased by offsets. Daubenyas should be quite dry 
while at rest.

_ There are about a score other species, but none are worth men- 
tion, either as ornamental or useful plants.
