OP ORNAMENTAL EXOTIC PLANTS. 
117 
t 
species ; aud the flowers, which are in very dense heads, have a scarlet standard with a yellow spot in the centre, 
: and the wings and keel purple. The plant requires a loamy soil, and it should be repotted once, if not twice, a 
j year. Specimens trained spirally round a barrel-shaped trellis are said, in “ Paxton’s Magazine,” to have a much 
better appearance and to flower better than those which are supported erect, or trained to the rafters of a green- 
house. The species was introduced about 1840. 
OTHER SPECIES OF ZICHYA. 
Z. TRICOLOR Hort. 
This plant is very nearly allied to Z. pannosa, and, like that species, it was introduced from the Swan River, 
about 1840. The principal differences between the plants are, that in Z. tricolor the heads of flowers are much 
less dense, the stems of the plants are weaker, and the flowers larger. 
Z. INOPHYLLA Hugcl. 
A very showy and strong-growing species, with large heads of scarlet flowers, which have a very peculiar 
appearance, from the calyx of each separate flower being thickly covered with short black hair. The leaflets of this 
species are remarkably large. It is a native of New Holland, and was introduced about 1826. It is a very free- 
growing species, and when planted in the free ground of a consei’vatory, it will soon attain a height of four 
or five feet. 
Z. GLABRATA Hiigel. 
This is a pretty little plant, with very small clusters of flowers, slender w'ffy stems, and smooth leaves, which 
are almost entirely destitute of hairs. The species was introduced in 1833. 
Z. SERICEA Hiigel. 
This species was figured under the name of Kennedya dilatata in the “ Botanical Register ” for 1832. It is 
most nearly allied to Z. inophylta, which it resembles in the black hairs which clothe the calyx of its flow’ers, but 
they are not so conspicuous as in the previously mentioned species. It was introduced in 1830. 
GENUS XLII. 
PHYSOLOBIUM Benth. THE PHYSOLOBIUM. 
Un. Syst. DIADELPHIA DECANDRIA. 
Generic Character. — Calyx campanulate, bilabiate, five-toothed. 
Vexillum broadly orbiculate, spreading, somewhat hardened at the 
base, longer than the wings. Wings adhering to the keel for about 
half their length. Keel curved, obtuse, shorter than the wings or 
equal to them. Stamens distinctly diadelphous, the upper one free ; 
filaments straight, and without any joint; anthers all alike. Ovary 
with several ovules. Style short, ascending. Stigma capitate. Legume 
oblong, imperfectly divided into several cells by a cellular substance 
which at length disappears. Seeds strophiolate. 
Desceiption, &c. — This is one of the genera into which the old genus Kennedya was divided. The name of 
Physolobium signifies a bladdery or inflated pod.
