PTEROCARPUS ERINACEUS. ORD. XXIV. Papilionacezx. 45 
a yellow colour, papilionaceous, and consisting of a roundish, heart-shaped, 
spreading vexillum, or standard, with a waved margin and short claw, two 
lanceolate wings, and a short carina. The filaments are alternately longer, 
connected at the base, and supporting roundish yellow anthers. The germen 
is oblong, pubescent, with a curved, thread-shaped, style, and simple stigma. 
The fruit is a compressed, orbicular pod, with a leaflike edge, covered at 
_the sides with white bristles, containing a single kidney-shaped seed. Fig, 
(a) represents the calyx, (6) the stamens, (c) the pistil, (d) standard, (e) one of 
the wings, (f) the carina, (g) the legume, (/) a leaflet,—all the figures more 
or less magnified. 
This tree is a native of Senegal, and is described by Lamarck under the 
specific name of erinaceus, in the Encyclopédie Méthodique* The plant 
loses its Jeaves in the month of November, and the flowers appear in Decem- 
ber.t The officinal kino of commerce is the inspissated juice of several dif- 
ferent plants. The London College considers the best sort of kino to be the 
product of the tree we have here described. The Edinburgh College, how- 
ever, has inserted kino as the inspissated juice of the Eucalyptus resinifera, 
or brown gum-tree of Botany Bay ; while the Dublin College (on the author- 
ity of Dr. Roxburgh) has named the Butea frondosa, as the plant which fur- 
nishes the kino of the shops. Besides these, it seems there are several other 
plants which produce this substance, or substances bearing a great resem- 
blance to it.t Hence it appears, that the products of several trees, have, at 
various periods, been imported into this country, under the specific name of 
kino; and that the chemical properties of these different kinds vary consi- 
derably. 
Kino is attained by incisions made in the branches of the tree, when the 
juice flows out, at first of a pale red colour; but as it concretes, becoming of 
a deep blood red, eee so extremely brittle, that it requires much care in 
collecting.

i This kind of Kino, we are told by Dr. A. Duncan, “is certainly obtained from the 
Eucalyptus resinifera, or brown Gum-tree of New South Wales, by allowing the juice, 
which either flows from it spontaneously, or is procured by wounding the tree, to harden
