BOTANICAL NOTICES OF NEW PLANTS. 



Gompholobium Versicolor. Lindl. Changeable Gompholobium. Bot. Reg. 

 N. S. t. 43. This is a handsome species, bearing numerous large reddish-brown 

 flowers. It is a native of the Swan River, and was introduced by R. Mangles, 

 Esq., of Sunning Hill, from whose plant the drawing was made. 



It appears to be allied to G. spar sum of Allan Cuningham, which was found 

 by that zealous collector and botanist in King George's Sound. It agrees with 

 the above species in its dark flowers and short petioles, but its branches are much 

 more angular ; the leaves are distinctly rising on the upper side, and those near 

 the bottom of the branches are much shorter and broader than the others. G. 

 versicolor differs from G. tenue in its short petioles, and racemose dark flowers ; and 

 from G. sparsum in the leaflets not being at all veiny, and all of equal sizes. 



It strikes readily from cuttings taken either in autumn or spring. The soil 

 most congenial for its growth, is peat and sand, and about one fourth of good 

 loam. If the young plant is tipped, it will send out lateral shoots, and will form 

 a handsome bust. 



PQLYGONEiE. 



Polygonum amplexicaule. Don. Stem-clasping Polygonum. Bot. Reg. 

 N. S. t. 46. This is a showy Polygonum, bearing spikes of reddish-crimson 

 flowers about six inches long. It is a native of Nipal, where it appears to be 

 common. It is, in consequence of describing from dried specimens, under various 

 names, P. speciosum, ambiguum, oxyphyllum, and petiolatum. The seeds from 

 which this plant was raised, were received by the Horticultural Society of London 

 from Dr. Falconer, the superintendant of the Botanical Garden of Saharunpur. 

 No varieties, Dr. Lindley observes, were seen amongst the seedlings, and it is 

 probable that the differences which have been observed among the dried 

 specimens, were produced by local causes. It grows to the height of about four 

 feet, and is a hardy perennial, and flowers in July and August. It should be 

 treated as an amphibious plant, so that its root may reach the water ; and is, 

 therefore, well adapted for planting on the margins of pools and lakes. 



It may be increased by division, or by seeds. Bot, Reg t 



ERICINEiE. 



Clethra Tomentosa. Lam. Downy Clethra. Bot. Mag. t. 3745. This is 

 a small handsome shrub, which bears racemes of white and fragrant flowers in the 

 end of autumn. Dr. Graham doubts whether it is distinct from C. alnifolia ; but 

 he is certain that it is the true plant of American authors. C. alnifolia appears 

 to Dr. Graham only to differ in the total absence of down, C. tomentosa having 

 the under surface of the leaves and young branches hoary. C. alnifolia inhabits 

 the middle and northern states of America ; C. tomentosa the southern ; and was 

 sent to the gardens of this country, by the late Mr. Drummond, from New 

 Orleans. Bot, Mag.

Gesnera Marchii. Wailes. Mr. March's Gesnera. Bot. Mag. t. 3744. 

 This is said to be a very handsome and distinct species of Gesnera, bearing
