= [rideæe. A small genus of greenhouse or hardy bulbous 
plants, closely allied to Sisyrinchium. The species in 
cultivation are very pretty hardy plants, but require 
protection from severe frosts and excessive rains. They 
thrive best in a warm, light soil, and make pretty plants 
` for rockwork.  Propagated by separating the offsets 
during autumn. This genus has been much misunder- 
stood. Among the plants which have been referred to it 
are some which now find places in the genera Aristea, 
Sisyrinchium, Homeria, Marica, Morea, &e., &e. 
` B. aurantiaca. See Homeria aurantiaca. 
B. gladiata (sword-shaped). jl. yellow, thinly sprinkled with 
purple dots near the centre, handsome, nearly 2in. across.

B. spathacea (rush-like). l. rush-like, several feet in length ; 
flower-stem as long as leaves, bearing near extremity a cluster of 
pale yellow flowers, with narrow segments. Each flower lasts but 
one day ; as a good many, however, are developed in each spathe, 
there is a ee which lasts some time. 1832, Syn. Xyris

specimen on the lawn, or by frequented walks, where it 
will not be too closely surrounded by tall plants, it may be 
grown with marked effect. It also forms a good subject- 
for pot culture, and is largely used for sub-tropical bedding. 
The soil most suitable for its culture is a good fat loam, of 
considerable depth. pagated by cuttings, taken from 
the axils of the larger leaves, during early summer; or 
by young suckers, taken from established plants, during 
summer, as they will then flower the following season. If 
the former method is employed, the cuttings should be- 
pushed on, so that there are plenty of roots before the © 
winter sets in. The other two species require greenhou 
culture; but both are eminently suited for sub-tropical 
gardening, in any light rich soil, or well-drained airy 
situation. They are best propagated by seeds, ma: 
hotbed in spring, the seedlings being placed out from June 
to September. td x“

tings, made of young, rather firm, shoots, and placed in 
sand, under a glass. There are several other species besides 
the one given below, but they are not of much horticul-
