This species, which seems rare in India, has only, so
far as I am aware been found in Mysore. It is readily
known by its prickly fruit, being the only Indian species
of the tribe Hedysareas having that character.
Acrocarpus, (R. W.) Am.
Calyx sub-coriaceous, ebracteolate, campanulate, 5-
cleft, segments erect, the superior and inferior a little
larger. Torus covering the tube: Petals __ oblong, .sub-
coriaceous, about equal, sessile, long persistent, inserted
on the mouth of the calyx and a little longer than its
lobes; aestivation sub-imbricate: Stamens alternate with
the petals, filaments broad at the base, subulate, two or
three times longer than the petals, straight; anthers
oscillatory. Ovary long, stipitate, (stipe free) oblong,
linear, falcate, pointed, with the snort incurved acute
style, many (about 15) ovuled. Fruit unknown.
This species is a large showy tree. The trunk of one
that I saw, I estimated at 50 feet high without a branch.
Leaves alternate, unequally pinnate, deciduous ; petioles
4-6 inches, long, round: leaflets 3-4 pairs, lanceolate,
acuminated, somewhat unequal at the base, 2-3
inches long, entire, pale beneath. The flowers largish,
expanding before the evolution of the leaves, scarlet
racemose. Racemes speciform, 6-8 inches, long, thickly
covered with flowers, the pedicels a line or line and half
long, recurved. Stamina nearly an inch long.

No, 12 Wight’s leones PI. Ind. Or. tab. 254.
Habitat.—The forests of Courtallum flowering in
February when almost naked of leaves. In this respect
resembling the Erythrinas.
The affinities of this genus in the order are not yet
clearly made out for want of fruit, but Dr. Arnott
thinks it referable to the tribe Cassiece of Ccesalpineee.

3. The same, the petals removed to show the calyx,
stamens and ovary.
4. Anthers, showing the ,glandular appendage whence
the generic name is derived.

enabling the error to be corrected in binding, I have numbered the explanations as they should stand in the series.
