without albumen. — Tall hard-woodecl trees, without prickles. Leaves twice 
pinnate, with numerous leaflets. Flowers yellow, in racemes forming terminal 
panicles. 
The genus consists of two or three tropical American species, one in S.E. Africa, and one or 
perhaps two in the Indian Archipelago, one of which is the Australian one. — Benth. 
1. P. ferrugineum (referring to the rusty covering), Benth. FI. Austr. ii. 
279. A large tree, the young branches petioles and inflorescence densely rusty- 
tomentose. Pinnte of the leaves 8 to 10 pairs ; leaflets 10 to 20 pairs or fewer 
on the lowest pinnas, oblong, very obtuse or retuse, oblique at the base, to fin. 
long, shining above, minutely rusty-tomentose underneath. Racemes 5 or 6in. 
long or more, forming a large terminal panicle. Pedicels very short. Bracts 
small, lanceolate, deciduous. Calyx 4 to 5 lines long, globular before opening. 
Petals rather longer, obovate, undulate, villous at the base. Pod about 3 to 4in. 
long, f to nearly lin. broad, shortly acuminate, narrowed at the base, glabrous 
or nearly so, with 1, 2, or 3 seeds. — Casalpinici ferruginea, Dene. Herb. Tim.

Hab.: Queensland, F. v. Mueller (without locality). 
In the Archipelago from Timor to the Philippines. Some Malacca specimens, perhaps 
belonging to a different although closely allied species, have the pods twice as long, with 3 or 4 
seeds. — Benth.

(After John Parkinson, a botanist of the seventeenth century.) 
Calyx divided nearly to the base into 5 subequal membranous, slightly 
imbricate segments. Petals 5, spreading stamens 10, free, scarcely decimate ; 
filaments pilose at the base ; anthers uniform, elliptical, dehiscing longitudinally. 
Ovary narrowed to the base, 8 to 10-ovulate ; style subfiliform, recurved in bud ; 
stigma terminal, minute. Pod narrow-linear, narrowed to each end, usually 
constricted between the subdistant longitudinally-disposed seeds, thinly coriaceous, 
longitudinally reticulate-striate, scarcely or not at all dehiscent. Seeds 1 to 6 or 
8, oblong or subcylindrical, albuminous. — Shrub or tree. Leaves bipinnate ; 
pinnae 2 to 4, with the rhachis much elongate, flattened, bearing numerous small 
oblong or linear, opposite or scattered leaflets, which are occasionally abortive ; 
common petiole very short or obsolete, spine pointed, the pinnae appearing as very 
long simply pinnate geminate or fascicled leaves at first sight. Flowers in lax 
axillary racemes, yellow ; bracts early caducous. 
A genus of 3 species (1 Cape and 2 American). 
1. P. aculeata (prickly), Linn.; DC. Prod. ii. 486. .Jerusalem Thorn 
of the West Indies. A glabrous bush or small tree, armed with sharp woody 
spines, which represent the primary rhachis of a bipinnate leaf, and have 2 to 6 
pinnae congested in their axils. Pinnae 6 to 12in. long, the rhachis much 
flattened, so that when the very minute obtuse oblanceolate leaflets have fallen or 
are not developed they resemble the phyllodes of an acacia. Racemes lax, shorter 
than the leaves. Pedicels long, slender, erecto-patent. Corolla tender, yellow, 
about Jin. Pod 3 to 4in. long. 
Hab.: This South American plant was first introduced for the purpose of hedge-making, but 
has strayed out in a few localities.

(The Greek Kasia of Dioscorides.) 
(Cathartoearpus, D. Don.) 
Sepals 5, somewhat unequal, much imbricate, the outer ones the smallest, 
scarcely connected at the base. Petals 5, spreading, nearly equal or the lower 
outer ones rather larger. Stamens usually 10, free, either all nearly equal and
