BOTANICAL NOTICES OF NEW PLANTS. 



PHILADELPHACEiE. Lindl. 



Philadelphia hiksutus. Nuttall. Hairy Philadelphus. Bot. Reg. N. S. 

 1. 14. A hardy shrub, the smallest of all the genus, flowering from about the 

 middle of July. It was discovered by Mr. Nuttall on the rocky banks of the 

 French broad river Tennessee, near the warm springs, and is readily distin- 

 guished by its undivided four-grooved stigma. It may be increased by cuttings, 

 or perhaps more readily by layers of the young wood, at the latter end of 

 August. Bot. Reg. 



P. Gordonianus. Lindl. Mr. Gordon's Philadelphus. Bot. Reg. p. 21. 

 This is described to be a species of great beauty, sent from North-west America 

 by Mr. Douglass, who found it in such abundance that it formed underwood 

 along the banks of the Columbia river. Its height is from eight to ten feet. It 

 differs from the other species by its deeply-serrated leaves, flowers growing in 

 close clusters, broad reflexed calyx, and nearly superior fruit. Bot. Reg. 



CACTEiE D. C. TRIBE ( Opuntacece). 



Mammillaria atrata. Hort. Mackie. Dark-green Mammillaria. Bot. Mag. 

 t. 3642. A beautiful plant from the choice collection of Mr. Mackie, of Laken- 

 ham, near Norwich, where, by that gentleman's skilful management, it flowers 

 in high perfection. Pfeiffer, in his Enumeratio Cactearum, refers M. atrata of 

 the gardens to the M. rhodantha, Link et Otto, Hort. Berolinensis, from which 

 species this plant is wholly different. Its native country does not appear to be 

 correctly known. Bot. Mag. 



COMPOSITE. Vail. 



Cosmus scabiosoides. H, B, et K. Scabious-like Cosmus. Bot. Reg. N. S. 

 t. 15. A beautiful species, originally found by Humboldt and Bonpland on the 

 western slope of the mountains of Mechoacan, near Pazcuaro, nearly 7000 feet 

 above the sea. It has also been met with near Tlalpuxahua. The seeds from 

 which this species was raised were imported from Mexico by G. F. Dickson, 

 Esq., F. H. S., and presented to the Horticultural Society of London. It is' 

 perennial, and tuberous-rooted, and may be increased, propagated, and culti- 

 vated, after the manner of the Dahlia. Bot. Reg. 



Dahlia Barkers. . Caule hirsutissimo, ramosissimo ; foliis impari pinnatis, 

 foliolis ovatis, inciso-dentatis ; floribus conniventibus ; petalis lanceolatis, pallide 

 roseis cum purpureis striatis. 



This very distinct and delicate Dahlia was imported in the spring of 1837, by 

 G. Barker, Esq., of Springfield near Birmingham, with whom it flowered the 

 same autumn. It grows about three feet high, is branched from the base, and 

 forms a complete bush of from about six to eight feet in circumference. The 

 stems are very hairy, indeed almost bristly. The flowers are of a pale rose 

 colour, striped with purple. The petals are delicately shaped, and connivent, 

 forming a kind of cup when fully expanded. It was found by the collector in 

 the forests in the vicinity of Valladolid, growing on the rocks in light black
