branches and stalks, and large leaves of 11 -31 lance-oblong pointed and serrate 

 leaflets. Worthy to be planted for ornament. 



R. glabra, SMOOTH S. Shrub 2 -12 high, in rocky places, like the 

 last, but smooth, the leaflets whitened beneath. Var. LACINIATA, in Penn., 

 has the leaflets cut into narrow irregular lobes : planted for ornament. 



R. copallina, DWARF S. Shrub l-5 high, in rocky or sandy ground, 

 spreading by subterranean shoots ; with downy stalks or branches, petioles 

 winged or broadly margined between the 9-21 oblong or lance-ovate oblique 

 leaflets, which are thickish and shining above ; juice resinous. 



t- +- Leaves of 3 cut-lobed leaflets: flowers light yellow, in spring before the leaves 

 appear, dioecious, in small scaly -bracted and catkin-like spikes.

Woody plant*, climbing by tendrils, with watery and often acid 

 juice, alternate leaves, deciduous stipules, and small greenish flow- 

 ers in a cyme or thyrsus ; with a minutely 4 - 5-toothed or almost 

 obsolete calyx ; petals valvate in the bud and very deciduous ; the 

 stamens as many as the petals and opposite them ; a 2-celled ovary 

 with a pair of ovules rising from the base of each cell, becoming 

 a berry containing 1-4 bony seeds. Tendrils and flower-clusters 

 opposite the leaves. 



1. V1TIS. Calyx very short, a fleshy disk connecting it with the base of the 



ovary and bearing the petals and stamens.

 East, furnishing the principal grapes of our greenhouses, &c. ; some varieties 

 nearly hardy N. : leaves green, cottony only when very young. 



* Flowers more or less polygamous (some plants inclined to produce only stami- 



nate flowers], exhaling a fragrance like that of Mignonette : native species.
