30 ft., 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.

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

Synonyme. Forsythia Walt., not of Vahl. 
Derivation. From decuma, 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., ili. 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 44 ft. org 
5 ft., in the open air, in the climate 
of London. The only place in 
which we have seen a vigorous 
growing plant of : Decumaria 
is in the garden of the Rev 
Thomas Garnier, at Bishop Stoke, 
in Hampshire, where, in 1834, it had attained the height of 12 ft., trained 
against a wall. To what the specific name applies we do not know.
