This genus was established by the late Sir James 
Edward Smith, formerly president of the Linnean 
Society, in honour of his distinguished friend, Wil- 
liam Roscoe, Esq. F. L. S., a man of eminent 
talents and virtue. 
The plant which we now figure, it will be seen 
by the plate of it, is of very ornamental character ; 
the protection of the stove, on its introduction to 
this country, was thought indispensable to its proper 
management; it has, however, proved quite hardy 
under ordinary circumstances. To secure success 
in its culture, strict attention should be paid to 
the dryness of the situation in which it is planted, 
a condition which cannot be too much insisted 
on in the culture of all plants of doubtful hardi- 
ness; and we would advise that moss or tan be 
put on the border in winter, over the roots. If 
kept in a pot, the soil should be a mixture of 
peat, loam, and sand. It may be divided for 
increase; or raised from seeds, which should be 
sowed in a cold frame, and they will blossom in 
the second season. Reference to “Acclimatisation,” 
in the Auctarium, would here be useful.
