OF ORNAMENTAL PERENNIALS. I43 
1.— HOSACKIA BICOLOR, Doug. THE TWO-COLOURED HOSACKIA. 
Synonyme. — Lotus pinnatus, i/ooA;. I • Specific Character Plant glabrous; flowers umbellate, bract- 
Engravings — Bot. Reg. t. 1257; and Bot. Mag. t. 2913. I lese ; leaves with seven — nine leaflets. (G. Don.) 
Description, &c. — This plant, as it is represented in the Botanical Register, is decidedly yellow and white, 
both being distinctly and clearly marked ; but in the Botanical Magazine the flowers are all yellow, part being 
rather fainter than the rest. The plant was found by Douglas on the banks of the Columbia, and introduced by 
him in 1823. It is quite hardy, and will grow in any common garden soil. 
OTHER SPECIES OF HOSACKIA. 
H. STOLONIFERA, Lindl. 
The flowers are in clusters, and they are red and yellow, but neither colour is distinct. The species is a native 
of California, whence it was introduced in J 833. It is a good shrubbery plant where any wall or other uninterest- 
ing object is to be hidden, as it grows rapidly, and soon forms a thick bush three feet high, and wide in 
proportion. In a botanical point of view it is interesting, from its embryo having sometimes three cotyledons. 
It flowers in June, and produces abundance of seeds in August ; it also sends up numerous suckers from its 
stoloniferous roots. 
GENUS VIII. 
DALEA, Michx. THE DALEA. 
Lin. Syst. MONADELPHIA DECANDRIA. 
Generic Character. — Calyx five-cleft or five-toothed, sometimes 1 stamens ; vexillum short, free ; stamens ten, monadelphous ; legume 
beset with glands ; wings and carina adhering to the tube of the | ovate, one-seeded, shorter than tho calyx. (G. Don.) 
Description, &c. — This genus, though possessing plants of no great beauty, is interesting, from having 
been the cause of the well-known flower, the Dahlia, having its name changed by some botanists to Georgina. 
The two names being, however, both differently spelled, and differently pronounced, the name Dahlia has been 
restored to the original use. The name of Dalea was given to the present genus in honour of Mr. Thomas Dale, 
an English botanist of the last century. 
1.— DALEA MUTABILIS, Willd. THE CHANGEABLE-FLOWERED DALEA. 
Enobavtogs. — Bot. Mag. t. 2486 ; and om fig. 6 in Plate 35. 
Specific Character. — Erect, branched, glabrous ; leaves with five 
—ten pairs of obovate or obcordatc leaflets ; spikes of flowers cylindri- 
cal, at length much elongated, pedunculate; peduncles hispid just 
under tho spike ; calyx glabrous, striated with ten black nerves ; 
bracteas ovate, terminated by a bristle, shorter than the calyx. 
Description, &c. — A little half-hardy plant, which may be grown as a biennial in the open ground ; but 
which becomes shrubby when kept in a greenhouse or stove. It is a native of Mexico, whence it was introduced 
in 1821. 
OTHER SPECIES OF DALEA. 
D. AUREA, Nutt. ; PSORALEA AUREA, Poir. 
A native of Upper Louisiana, with golden yellow flowers ; introduced in 1811.
