ERYTHRINA, Linn. 
E. phlebocarpa, Bail. (n. sp.). (Name from the prominent veining on the 
pods.) Deciduous tree ; branchlets thick and more or less covered with smnall 
black prickles. Petioles nearly terete, about 8 in. long, unarmed. Leaflets 3, 
membranous, the terminal one often 7 in. long and 8 in. broad, on a petiolule of 
about 4-in. at the end of a rhachis of about 23 in., rhomboidal in form; the lateral 
leaflets smaller but very similar in form, on petiolules of about }-in. Stipelle 
gland-like. Peduncles terminal, stout, unarmed or a minute prickle or two near 
the base, 5 or 6 in. long, or with the raceme sometimes 15 in. Flowers crowded, 
red, usually in whorls of 4 upon the rhachis, the whorls scarcely 4-in. apart. 
Pedicels 4 lines long. Calyx campanulate, oblique at the top, about 6 lines long, 
marked with longitudinal lines. Standard 2 in. long, slightly recurved, tapering 
towards the base, about 7 or 8 lines broad when expanded, but usually infolded 
and so appearing narrower, apex acuminate ; wings and keel petals oblique- 
oblong, about as long as the calyx. Pod lor 2 seeded, 3 to_5 in. long, about 
lin. broad over the seeds, much constricted between them, with along seedless 
base and long acuminate apex; the exocarp marked on the outside by strong - 
reticulate veins, endocarp separating from the exocarp and long retaining the 
seeds. Seeds oblong, red, 7 lines long, 4 lines broad, flat on the bottom or 
hilum side, and showing a rather sharp longitudinal ridge on the upper side.

A. somersetensis, Bail. Queensland Agricultural Journal, Sept., 1897. 
From specimens to hand from Mr. I. L. Jardine, of Somerset, I am enabled to 
add the following to the description already published :— 
Flowers white in pedunculate cymes, generally from 6 to 8 at extremities 
of the branchlets. Peduncles from 1 to 2 in. long, angular and hoary pubes- 
cent. Cymes trichotomous. Bracts minute, ovate-lanceolate, ciliate. Calyx- 
segments thick, much imbricate, obtuse, pubescent, the keel prominent, about 
1 line long and_ nearly as broad, without glands inside at the base. Corolla- 
tube twice as long as the calyx, longitudinally corrugated, tomentose except 
at the base, lobes rather broad, not quite as long as the tube, densely covered 
on the face with white curly hairs, no ring of hairs at the orifice, but a rather 
broad band of short hairs below where the anthers are attached to the tube. 
Ovary glabrous. ‘Follicles 10 to 15 in. long. Seeds flat oblong, covered on 
both faces with short brown hairs, and ciliate with long bright-brown hairs, 
which at each end exceed in length that of the seed itself. 
It is probable this tree might yield a rubber, this material being obtained from other species 
of the genus,
