will flower the next winter or spring. There is a much quicker method 

 of raising a stock of flowering bulbs of C. Persicum, and that is to sow 

 the seed as soon as ripe, and to keep the plants growing all the winter in 

 the stove, by which process they form fine large bulbs by May of the fol- 

 lowing year, when they may be dried off and ripened, and will all flower 

 the next spring. As to the selection of species and varieties, it is so true 

 that all are beautiful, that we advise the lovers of these plants to secure 

 as many species and varieties as possible. The most useful species are 

 Persicum, coum, hedercefolium, and Earopcemn. Of Persicum there are 

 many varieties, some very fragrant, others but slightly so, and for colours, 

 the most distinct are alhiflorum, white ; lilaceum, lilac and white ; and 

 odoratum, red and white. 



NOTES ON NEW PLANTS. 



ClEKODENDEON TnOMSONiE. — In 



the third volume of the Floral 

 WoELD, p. 130, we gave an account 

 of the interesting Clerodendron cruen- 

 tum, which was then but lately intro- 

 duced into this country by 

 Messrs. Veitch, of Chelsea 

 and Exeter. We have now 

 to introduce to our readers' 

 notice another very beauti- 

 ful species, to which the 

 name of Thomsons) has been 

 given. It was discovered 

 by Mr. Barter, a botanist, 

 and some dried specimens 

 were preserved in the Her- 

 barium at Kew ; but it 

 was subsequently discovered 

 growing in abundance on 

 the borders of Old Cala- 

 bar, by Mr. Thompson, who 

 had the good fortune to in- 

 troduce living specimens 

 into Europe. It was first 

 bloomed in the Botanical 

 Garden of Edinburgh, in 

 1862, in a stove, where it 

 made a superb effect by 

 means of its numerous bun- 

 dles of lively flowers, the 

 calyces being as white as 

 snow, and the corollas a 

 bright crimson. It will 

 either twine its long arms 

 round another plant, or grow recum- 

 bent upon the ground. It requires 

 shade in a warm greenhouse, where it 

 will grow to a considerable height, 

 but looks best trained in the form of 

 a pyramid. The soil should be rich 



and friable ; it requires frequent 

 syringing both above and below the 

 leaves, to keep it free from parasitical 

 insect enemies ; and may be easily in- 

 creased by cuttings.

 The genus Viola has for its type 

 Viola odorata, which is found abun-
