kinds should be sown in pots early in the spring, and placed either 
in a green-house or gentle hot-bed; and in May the plants should 
be planted out into the open border, in a warm dry situation. A 
light sandy soil will suit them best. The green-house species 
are all little shrubby plants, and grow freely ina mixture of sand, 
loam, and peat. They may be either increased by seeds, or 
young cuttings will root readily if planted in a pot of sand, and 
then placed under a hand-glass.

firmed Sir James Smith’s account of the flowers always being 
several feet under water, where he observed them to be con- 
stantly expanded, so that the impregnation actually takes place 
in that element. The leaves are about 8 or 10 lines long, awl- 
shaped.

sown in a pond or rivulet, with a sandy or gravelly bottom; or 
it may be preserved in a pot filled with gravel or sand, and then 
plunged in water,

vex valves, crowned by a short style. Seeds numerous in the 
cells, disposed in two rows. Calyx spreading. Petals dilated. 
Plants with the habit of Braya, which it agrees with in the 
structure of the flowers, and in the cotyledons being incumbent. 
To Subularia it is more nearly allied, in the cotyledons being 
narrow and 2-legged.

pots filled with a mixture of peat and sand, and treated as other 
alpine plants. They may be either increased by cuttings, made 
of the barren shoots, or by seeds.

Cult. This singular cruciferous plant should be raised m 
pots in a green-house in spring, when some of them may e 
planted out in the borders, others may be saved in the pots, 
and placed in an airy part of the green-house, where they w! 
produce seeds, although sparingly. A mixture of loam, peat, 
and sand suits it best. parng y
