Or. LeguminosoB. The soil best adapted to these 
pretty plants, is peat and sand, mixed with vege- 
table mould. They do best grown in pots, among 
the Alpine plants. They may be increased by 
dividing at the roots, or by young cuttings in sand, 
under a glass. Synonymes : 1. Acacia brackyloba.

Datura, Linn. An alteration of the Arabic name,

ornamental genus, but chiefly composed of plants 
possessing very deleterious qualities. The seeds of 
D. ceratocaulon will sometimes remain in the ground 
for several years before they vegetate. The seeds 
of aU the species require to be sown early in spring, 
on a hotbed, and when of sufficient size, they should 
be transplanted into a warm border, where they 
will flower better than if kept in pots. In the 
United States, the juice of D. stramonium is used 
in doses of from twenty to thirty grains, in cases of 
epilepsy, or of mania without fever,

at Oxford, and well known for bis physiological 
researches. Linn. 6, Or. 1, Nat. Or. Liliaceae. This 
is a very pretty, as well as a singular little plant, 
producing its beautiful yellow flowers in an umbel,

offsets.

j^diacecB. This is a genus of very beautiful ferns. 
The rootstock of D. canariensis curves over the side 
of the pot in which it grows, and being covered 
with close brown hair, it very much resembles a 
hare’s-foot; hence it is commoMy called the hare’s- 
foot fern. The species thrive well in a mixture of 
peat and loam, and may be increased by divisions 
at the roots, or by seeds. Synonyms: 1. Tricho- 
manes gibberosa.

an equal mixture of loam, peat, and sand ; cutting 
nearly ripened, of all the species, will root readily 
in sand, under a glass. Synonyms: 1. Duviesia
