Pentaclethra. | XLVII. § MIMOSE (OLIVER). 323 
scurty, eglandular ; pinne opposite or subopposite in about 10-13 
pairs; leatlets 14—18-jugate, obliquely oblong, obtuse, entire or emar- 
ginate, somewhat rigid, at length glabrous, shining above, oblique, mid- 
rib and venation prominent beneath ; 2-14 in. long, 5—5 lines broad, 
sessile. Stipules subulate, deciduous, Spikes long, narrow, inter- 
rupted or rather dense, solitary or in pairs from leatless nodes, pani- 
cled towards the extremities. Flowers ‘‘ yellowish,” sessile. Calyx- 
lobes broadly rotundate. Petals elliptic-oblong, spreading. Stamens 
and 10 or 15 filiform staminodia slightly thickened above, much exserted, 
Legumes 20-25 in. long, 3}—4 in. broad, narrowed to the base; valves 
thick and woody, at length becoming strongly revolute when dry. 
Seeds much compressed, various in circumscription, 2-2} in. long, 
1-2 in. broad ; testa crustaceous, shining.

The legumes have been sent home under the name of “ Opochala.” The seeds are 
edible, and yield an oil. The remarkable hygroscopicity of the valves of the mature 
legume I have described in detail in the “ Transactions of the Linnean Society,” xxiv. 
415. 
M. Baillon (Adans. vi. 206) indicates, under the name P? Griffoniana, a plant 
collected by M. Griffon du Bellay in the Gaboon country, of which he has not seen either 
flower or fruit, but which, from the foliage, he takes to be a new Pentaclethra. It pre- 
sents on the upper surface of the leaflets 1 or 2 small sessile concave glands. It is 
called N’tchiumbou. 
2. PARKIA, R. Br.; Benth. et Hook. f. Gen. Plant. i. 588. 
Flowers pentamerous, capitate; the upper flowers of the head her- 
maphrodite, the lower staminate or neuter. Calyx tubular with a 
shortly 5-lobed bilabiate limb, the two lower segments larger. Petals 
narrowly linear-spathulate, confluent below with the stamens, valvate 
or nearly so in estivation. Stamens 10, exserted; filaments adnate 
below with the petals, and consolidated at length with the base of the 
calyx-tube; anthers linear or oblong, unappendaged, pollen cohering 
in indefinite granular pollinia; staminodia 0. Ovary stipitate or 
sessile, multiovulate ; style slender, with a minute terminal stigma. 
Legume elongate (or oblong), compressed or subcylindrical, at length 
2-valved, coriaceous or somewhat woody. Seeds compressed, involved 
in fleshy at length dry and mealy pulp; testa coriaceous; cotyledons 
fleshy, radicle included; albumen 0.—Large unarmed trees. Leaves 
bipinnate, with very numerous leaflets. Flowers in dense globose or 
clavate many-flowered pedunculate at length pendulous heads, red 
or reddish brown, each subtended by a narrow bracteole, dilated at the 
apex. 
The anthers of Parkia are described by inadvertence in the Genera Plantarum (L. ¢.) 
as gland-appendaged. Mr. Bentham, however, in Hook. Journ. Bot. 1842, 328, pointed 
out that they were not glandular. 
Leaflets 3-6 lines, 1-nerved, in 50-70 pairs, pinne 14-30 pairs . . 1. P. biglobosa. 
Leaflets 6-8 lines, subtriplinerved, in 2-35 pairs, pinnew 8-12 pairs 2. P. intermedia, 
Leaflets 6-12 lines, tripliuerved, in 16-24 pairs, pinne 6-9 pairs. 3. P.jilicoidea.
