246 GREEN-HOUSE REPOTTING. [March 



minal panicles. 0. verrucbsa, foliage flat, lanceolate, and 

 white beneath, branches curiously warted. 0. fragrdns 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, lanceolate, 

 and a little serrated; flowers white in lateral bunches. It is 

 subject to the small white scaly insect, and ought to be care- 

 fully kept from them by washing. 0. rdsca has pink flowers. 

 0. paniculdta is also a fine species. They are all very easily 

 cultivated. (Soil No. 11.) 



OxylbMums, seven species, plants very similar to Callista- 

 chys, with ovate, cordate, light-coloured pubescent foliage, with 

 papilionaceous flowers. 0. obtusifdlium has scarlet flowers ; 

 0, retusum, orange flowers ; and 0. ellipticum, yellow flowers. 

 They grow freely and should be well drained; flower from 

 May to August. (Soil No. 6.) 



Passiftora; a celebrated genus of climbing plants, called in 

 common " Passion Vin-e." 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. hybrida, P. fragrans, P. Newmannia, P- Lemo- 

 chentziana, and are a 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 commonly 

 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 bp made to crow irregu, a~ly such as Ajax, Forget-me-not,
