30 it., if trained against a wall, or drawn up among trees, and other shrubs. 

 A plant, which we received from Colonel Carr, of Bartram's Botanic Gar- 

 den, near Philadelphia, in 1830, produced, in our garden at Bayswater, 

 trailing shoots from 6 ft. to 8 ft. long, in one season.

Spec. Char., $c. Leaves ovate, acuminated, denticulated, tomentose beneath. 

 Racemes terminal. Pedicels opposite. Lobes of calyx ovate, acute. (Don's 

 J ////., ii. p. 807.) A native of Nepal and Kamaon. Introduced in 1822 , 

 and growing to the height of 5 ft. or 6ft. P. triflorus, Royle observes, is, 

 probably, only P. tomentosus in a less advanced state. There are plants of 

 this very distinct species in the arboretum of Messrs. Loddiges, and in the 

 Hammersmith Nursery, but they have not yet flowered.

Derivation. From dccuma, a tenth ; in reference to the prevailing number, in some of the parts 

 of fructification, being ten. In De Candolle's description of the genus, it is stated that the teeth and 

 nerves of the calyx, the petals, the stigmas, and the cells of the capsule, are each usually ten. 



Description. A deciduous trailing and rooting shrub. A native of Lower 

 Carolina, in shady places. Introduced in 1785; but, being of little beauty, and 

 somewhat tender, not frequent in collections. It will grow in any dry soil, 

 and is readily propagated by cuttings.

Spec. Char., $c. A sarmentose shrub. Leaves 

 ovate-oblong, acute at both ends, glabrous, en- 

 tire or toothed at the tip. Buds hairy with 

 short rufous hairs. (Dec. Prod., iii. p. 206.) The 

 flowers, which appear in July and August, are 

 sweet-scented; but they are only produced in 

 favourable situations ; and the . 

 plant seldom rises above <H ft orM 

 5 ft., in the open air, in the climate 

 of London. The only place in 

 which we have seen a vigorous 

 jrowing plant of : Decumaria 

 in the garden of the Rev 

 Thomas Gamier, at Bishop Stoke, 

 in Hampshire, where, in 1834, it had attained the height of 1 2 ft., trained 

 against a wall. To what the specific name applies we do not know.
