inches long, for scions.” ‘The prin- 
cipal difficulty arises from the suc- 
culent nature of the Geranium 
shoots; as, if the bark be bruised 
or wounded during the operation, 
the grafts will not take; and they 
are also very easily broken off after- 
wards. 
The herbaceous and_tuberous- | 
rooted Geraniums require a much | 
m@qre sandy soil; and, when they 
have done flewering, they should 
be put on a dry shelf, near the glass, 
and very sparingly watered till the | 
spring, when they may be repotted, 
and treated as above. These may 
be propagated by cuttings, or divi- 
sion of the roots, in rather dry and 
sandy soil, and they rarely perfect 
their seeds in our greenhouses. 
The old genus Geranium has 
been divided by modern botanists | 
into fifteen genera; three of which 
already mentioned under the head 
of Erodium. The kinds usually 
grown in greenhouses belong to the 
genus Pelargonium; and of these 
where are nearly six hundred distinct | 
species, besides innumerable cross- 
sreeds, hybrids, and varieties.

natives of Europe and America,

Quellyon, Swt. (G. coccineum, Bot.

of Chili, with large orange-scarlet 
flowers. All the species are hardy, 
and require a light rich soil; they 
are propagated by seeds, or dividing 
the roots Some of the species are 
now called Sieversia ; the seed-ves- 
sels of Geum being hooked, and 
those of Sieversia ending in a 
straight feathery point.

species of this genus, G. glaber, a

curious plant. It is an annual, 
having a smooth stem and leaves, 
and growing about a foot high. The | 
flowers are flesh-coloured, and ex- | 
pand in the form of a star only 
when the sun shines upon them. 
The seeds are very curious, and it 
is from them that the plant takes 
its English name. They should be 
sown in the open border, in any

and the plants will flower in July 
and August.

forest or copsewood scenery. Their 
beauty in pleasure-grounds depends 
much on the smoothness or high-

of the trees or shrubs which repose 
on it.
