continues in succession nearly all the summer, makes 
it a very desirable plant, which, if properly managed, 
may be grown as freely as any other. Like the 
other tuberous-rooted kinds, it thrives well in an equal 
mixture of light turfy loam, peat, and sand; watering 
it only when quite dry, and never over the leaves ; 
those being so tender in this tribe, that by watering 
over them frequently they turn brown and look un- 
sightly, which also injures the health of the plants. In 
winter they must be kept quite dry till they begin to 
grow again, when they should be repotted and watered 
regularly. The best method of propagating them is 
from the little tubers of the roots. 
Our drawing was taken at the above collection, 
which continues inexhaustible in novelty, and where 
numerous beautiful and curious varieties are continu- 
ally making their appearance ; which enriches our 
work, and likewise the gardens of the curious.
