these plants should have been looked upon as desi- 
rable, when it is known that the number of species 
already described, consist of about three hundred 
Pelargoniums; eighty Geraniums, and fifty Ero- 
diums ; independently of hundreds of varieties. 
We should, long ago, have introduced to our rea- 
ders some of these ornamental plants for window 
and summer garden culture, hut that the pressuie 
of other subjects has prevented our doing so. In 
now taking up the genus Pelargonium, it seems to 
be desirable to give a clear view of the parents of 
the favourite novelties ; it will, therefore, be our 
first object to figure some of the old distinct species, 
which, by the bye, are now becoming objects of 
interest, amongst cultivators, and to follow these up 
by a selection of the best of the new seedlings, in 
each class, which have been propagated from them. 
The most remarkable of the old favourites is 
Pelargonium tricolor, now published. This, with 
its allies— elatum and carinatum, are suitable for 
window culture where fire is only used occasionally ; 
if constantly in the room they inhabit, the atmos- 
phere will he kept in too dry a state foi then healthy 
existence, and the result will be enfeebled plants, 
attacked by green aphis. This species should be 
potted in rough material, composed of equal por- 
tions of peat, or half decomposed leaves, and turfy 
loam, with a little very coarse sand. It should be 
fresh potted in July, and plunged into an open 
part of the garden, and watered when requisite. In 
the second week of September it should be taken 
into the house, and preserved with due regard to 
the above precaution.
