Cult. Drosera is 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 Dioncea musct- 

 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 in 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.

Cult. This plant should be grown in a marshy situation, or 



>'* ter in a peat soil ; if planted in pots half filled with some 

 of :<pliagnum, and set in pans of water, it will thrive 

 hen grown in water it should never be above 4 or 8 

 inches. .er its surface.
