244 GREEN-HOUSE — REPOTTING. [March. 
white beneath, branches curiously warted. O./ragrdns blooms 
in winter ; foliage and blossoms are both highly odoriferous ; 
the plant is much esteemed in China, and is said to be used 
to adulterate and flavour teas. Leaves are elliptic, lanceo- 
late, and a little serrated; flowers white in lateral bunches. 
It is subject to the small white scaly insect, and ought to be 
carefully kept from them by washing. 0. rosea has pink 
flowers. 0. paniculata is also a fine species. They are all 
very easily cultivated. (Soil No. 11.) 
Oxylbbiums, seven species, plants very similar to CaUista- 
ehys, with ovate, cordate, light-coloured, pubescent foliage, 
with papilionaceous flowers. 0. obtusifdlium has scarlet 
flowers; 0. rctfimm, orange flowers; and 0. cllipticum, yel- 
low flowers. They grow freely, and should be well drained ; 
flower from May to August. (Soil No. 6.) 
Passijidra ; a celebrated genus of climbing plants, called in 
common " Passion Vine." Those belonging to the green- 
house, flower during summer. Several of them are both 
beautiful and profuse in bloom, especially P. Kermdsine, P. 
princeps, P. hybncio, P. fragrans, P. Newmannia, P. Lemo- 
clientziana, and are very distinct species; the former is of a 
beautiful rosy crimson colour. (Soil No. 13.) 
Pelargoniums, Stork's Bill. This genus, so universally 
known among us as Geranium, from which it was separated 
many years ago, is a family of great extent and variety, for 
which we are principally indebted to the Cape of Good Hope. 
There are many hundred species, with upwards of twelve 
hundred beautiful and well-marked varieties, which have been 
obtained from seed. They are of every character, colour, and 
shade, of the most vivid description. The easy cultivation 
of the Pelargonium tribe, or Geraniums, as they are com- 
monly called, has rendered them very popular; also the 
agreeableness of scent and fragrance, of which many of them 
are possessed, makes them favourites. 
Their flowering season is also of considerable duration, espe- 
cially the bright scarlet and crimson varieties, which bloom 
from March till August, rendering them quite indispensable 
in collections. Some growers complain of their straggling 
habits ; but it is only those that do not know how to prune 
them : even some of the choice kinds of the present day 
could not be made to grow irregularly — such as Perfection, 
King, Mary, Margaret, and others; indeed, within these few
