244 QREEX-HDUSE — REPOTTING. \_March. 



white beneath, branches curiously warted. 0. fragrdns blooms 

 in winter; foliage and blossoms are both highly odorifer- 

 ous; the plant is much esteemed in China, and is said to be 

 used to adulterate and flavor teas. Leaves are elliptic, lan- 

 ceolate, and a little serrated; flowers white in lateral bunches. 

 It is subject to the small white scaly insect, and ought to b6 

 carefully kept from them by washing. rosea has pink 

 flowers. 0. paniculdta is also a fine species. They are all 

 very easily cultivated. (Soil No. 11.) 



Oxi/lbhiums, seven species, plants very similar to Callista- 

 chi/s, with ovate, cordate, light-colored, pubescent foliage, 

 with papilionaceous flowers. 0. oUusifolium has scailet 

 flowers; 0. retiisum, orange flowers; and 0. ellipticum, yel- 

 low flowers. They grow freely, and should be well drained; 

 flower from May to August. (Soil No. 6.) 



Passijldra; 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. Kermosine, P. 

 princeps, P. hyhriday P. fragrans, P. Kewmannia, P. Lemo- 

 chentziana, and are very distinct species ; the former is of a 

 beautiful rosy crimson color. (Soil No. 13.) 



Pelargmiiums, Stork's Bill. This genus, so universally 

 known among us as Gerdnium, 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, color and 

 shade, of the most vivid description. The easy cultivation 

 of the Pelargonium tribe, or Gerdniiims, 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 favorites. 



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
