be done when the pods are perfectly 
dry, and consequently after the 
warmest part of the day, rather

from their low stature and the bril- 
liancy of their flowers, look exceed-

should be grown in sand and peat,

should be well drained with cinders. 
| Grxse‘miom. — Apocy'nee. — A 
pretty climbing evergreen shrub, 
| generally kept in the areenhouse or 
conservatory, and generally known 
as Bignonia sempervirens, a native 
of South Carolina. It is grown in 
a compost of sand and peat, and it 
is propagated by cuttings struck 
under a glass. 
Geni'sta.— Leguminose.— There 
are above fifty distinct species of 
Genista, most of which will live in 
| the open air in British gardens, but 
some of which are greenhouse shrubs. 
They are all very handsome, from 
the profusion of their bright yellow 
pea-flowers. The greenhouse kinds 
should be grown in peat and loam, 
and are propagated by cuttings un- 
der a glass, which should be taken 
off frequently and wiped, or they 
| will damp off.

| GeEnTIA\NA.—-Gentiandcee.—- Well- 
known plants, generally with pretty 
flowers, and tonic properties. G. 
acatlis is frequently used as an 
edging plant, and it is remarkable 
for the brilliant colour of its flowers, 
_which are large, and of a deep ma- 
_zarine blue. All the Gentians re- 
quire abundance of free air, and 
will not grow well in the smoky at- 
mosphere of a town. They should 
_be grown in a light rich soil, and 
_do best in a mixture of loam and 
peat, enriched with a little vegetable 
mould. G. acatilis does best in peat 
alone. ‘The perennial kinds are in- 
creased by dividing the root, and 
the annual ones by seeds, which 
should be sown as soon as ripe, as, 
if left till spring, they will not come 
up till the second year.
