1066 ARBORETUM AND FRUTICETUM. PART ITI. 
shrub, of less vigorous growth, and somewhat more tender, than the 
preceding species. It is a native of North America, on the sea coast, from 
Carolina to Florida, and on the banks of the Mississippi; flowering from 
July to September. It was introduced into British gardens in 1812, and 
grows to the height of 3 ft. or 4 ft., retaining its leaves, in mild seasons, 
through the greater part of the winter. There were plants in the Twicken- 
ham Botanic Garden, Cambridge Botanic Garden, and in that of Bury St. 
Edmunds, a few years ago. 
B. glomeratiflira Michx. Fl]. Amer., 2. p. 125., Pursh Fl. Amer. Sept., 2. 
p- 523., is described as having the leaves smooth, cuneately obovate, toothed 
towards the point ; the heads of flowers axillary, sessile, remote ; and the scales 
of the calyx brown above. It is a native of Virginia and Carolina, in woods 
on the sea coast, flowering from August to October; but it has not yet been 
introduced. 
B. Dioscéridis W., Rauw. Itin., t. 54., is a native of the Levant, and is generally kept in the green- 
house or cold-pit ; though there can be no doubt that, if it were thought worthy of cultivation, it 
would stand against a conservative wall.

Spec. Char., §&c. Leaves lanceolate, deeply serrated, 
rough with dots. (Willd. Spec. Plant.) A native of 
North America, from New England to Florida, on 
the sea coast; flowering in August and September. 
Cultivated in Britain in 1711. It grows to the 
height of 3 ft. or 4 ft., and, in sheltered dry situa- 
tions, is tolerably hardy; but, when freely exposed 
in moist soil, it is apt to be killed to the ground in 
severe winters. It is readily propagated by cuttings; 
but, not being a plant of much beauty, it is seldom met 
with in collections.— I. imbricata Willd. is described by 
Pursh as a smooth shrub, with linear lanceolate entire 
leaves, found on the sea coast, from Carolina to 
Georgia. It has not yet been introduced.

Description. Diminutive evergreen undershrubs, natives of the south of 
Europe; of easy culture and propagation, by cuttings, in any poor sandy soil.
