Cult. Dróserais a singular and beautiful genus of plants, 
with their leaves ornamented with red glandular hairs, discharg- 
ing from their ends a drop of viscid acrid juice. These hairs 
have been thought irritable, so as to contract when touched, im- 
prisoning insects, somewhat in the manner of the Dione a musci- 
pula or Venus’s fly-trap. They all grow in their places of 
natural growth on mossy turfy bogs ; those species, natives of 
Europe and America, grow among sphagnum on a peat, gravelly, 
or sandy soil, particularly the American species on the latter soil. 
They thrive best in cultivation in small pots, which should be 
filled three parts full of peat earth and some sphagnum planted 
on it, the plants should be then planted in the moss, and the 
pots should be placed in pans of water, or in boxes m the same 
manner, and even then the hardy species should be placed in . 
the greenhouse, and those species from New Holland and the 
Cape of Good Hope, as well as those natives within the tro- 
pics, should be placed in the stove. They are all increased by 
seeds, which should be allowed to sow themselves, but as the 
seeds will not vegetate after a voyage, plants of the foreign species 
must be introduced in pots or boxes, in the same manner as re- 
commended for growing them.
