P. SUBUMBELLATA Eooh. 
Another species from Van Diemen’s Land, with small heads of orange-yellow flowei’s. It was introduced 
in 1832. 
P. ROSMARINIFOLIA Lindl. 
■ This species was also introduced in 1832, hut it was obtained from the south coast of New Holland. The 
leaves closely resemble those of the Rosemary, and the flowers are somewhat like those of P. subumbellata, but 
with rather larger heads. 
There are several other species of Pultensea, hut they are not generally found in greenhouses. 
OTHER GENERA OF LEGUMINOUS PLANTS ALLIED TO SOPHORA. 
DAVIESIA Smith. 
A genus of very neat little shrubs, with axillary racemes of small bright-yellow flowers which are produced in 
very great abundance. The most ornamental species is D. latijolia, which has broad flat leaves ; and the most 
curious kind is D. jimcea, which has no leaves at all. They are all of very easy culture, and they should be grown 
in light and somewhat sandy peat, with abundant drainage. They are all natives of Australia. The genus wns 
named in honour of the Rev. H. Davies. 
MIRBELIA Smith. 
Dwarf plants, with purple or yellow flowers, which are rather small, and not very ornamental. The genus is 
named in honour of Professor Mirbel, a celebrated French botanist. 
CALPURNIA Meyer. 
Cape plants, with rather ornamental flowers, which in one species are pink, and in others yellow. 
Burtonia, Jacksonia, Viminaria, Gastrolobium, Phyllota, and several other genera, belong to this division of the 
Leguminosse. 
GENUS XV. 
HOVEA R. Br. THE HOVEA. 
Lin. Syst. DIADELPHIA DECANDRIA. 
Generic Character. — Cah'x bilabiate ; upper lip semi-bifid, broad and refuse, lower one tbree-parted. Keel obtuse. Stamens all connected, 
the tenth or upper one only more or less free. Legume sessile, roundish, ventricose, two-seeded. Seeds stropbiolate. (G. Don.') 
Description, &c. — Veiy ornamental little plants, generally with blue or pui-ple flowers, which are small, but 
produced in great abundance. The genus is named in honour of Hove, a Polish botanist. The form and colour 
of the flowers are very nearly the same in all the species. 
I.— HOVEA CELSI BonpL CELS’S HOVEA. 
Synonyme. — Platycbilum Celsianum Del. j Specific Character. — Leaves lanceolate, and somewhat rhomboid. 
Engravings. — Bot. Reg., t. 280 ; Paxton’s Magazine of Botany, bluntish, and mucronate ; peduncles axillary, many-flowered ; branches, 
vol, iii., p. 241 ; The Botanist, t. 40. calyxes, and bracteas rather pilose. {G. Don.) 
Description, &c. — This plant is generally considered the most beautiful of the genus, from the brilliant colour 
and great abundance of its flowers. It was first raised in Europe from Australian seeds by M. Cels, a French 
nui’seryman. The species requires care in its cultivation, as it is easily killed by excess of either drought or 
moisture, but it amply repays the care taken df it. It was introduced in 1818.
