Texas, Drummond!—Not being able at present to consult the figure of
Oaramlles, we are in doubt whether the Texan plant be the D. longifolia, DC.
~ he leaflets are for the most part obtuse and mucronate. The keel, moreover
is not very obtuse”, and the seeds are subglobose.

Calyx campanulate, somewhat obliquely truncate, 5-toothed; teeth small,
rather obtuse, nearly equal. Vexillum reniform, very short and broad, slightly
unguiculate: wings oval-oblong: keel-petals coherent above the middle.
Stamens diadelphous. Style short, incurved at the summit. Legume elliptical
oblong, compressed, acute at each end, stipitate, cuspidate with the
style, 1-celled, 2-valved, 2-seeded; valves at length separating into an exterior
rather coriaceous membranous portion, and an internal membrane which
encloses the seeds. Seeds compressed, transversely oblong: radicle thick
indexed. An annual glabrous herb. Leaves abruptly pinnate, with numerous
leaflets; the petiole ending in a bristle : primordial leaves simple, ovate.

—Plant 4-6 feet high. Leaflets linear-oblong, mucronate. Peduncles filiform,
shorter than the leaves, 4-8-flowered. Calyx very short. Legume
about 2 inches long, on a slender stipe; the outer coriaceo-membranaceous
portion at length falling away, leaving the seeds enclosed in the thin white
inner membrane.

segments shorter, approximated or cohering. Vexillum broad and large:
keel obtuse. Stamens diadelphous, deciduous. Style bearded along the inside
(next the free stamen). Legume many-seeded, compressed, nearly sessile,
the seminiferous suture margined; valves flat and thin. Seeds flat.—
Trees or shrubs (N. American), usually bearing stipular spihes. Leaves
unequally pinnate. leaflets petiolulate, stipellate. Flowers showy, white or
rose-color, in simple usually pendant axillary racemes.—Locust-tree. 1

Fertile soils, particularly west of the Alleghany Mountains to Arkansas!
not indigenous north of Pennsylvania, or near the sea-coast in the Southern
States. May-June.—Tree 20-70 or 90 feet high: wood yellowish, compact
and very durable. Leaflets 4-8 pairs, with minute rigid setaceous partial
stipules. Racemes 3-5 inches long. Flowers as large as a Pea-blossom,
white, fragrant. Legumes 2-3 inches long, about half an inch wide, 4-6-seed-
ed.— Common Locust-tree.

legumes glandular-viscid; leaflets ovate; racemes crowded.— Vent. Iwrt.

Mountains of Georgia and Carolina. May-June.—Tree 20-40 feet high.
Leaflets 5-7 pairs. Racemes rather ovate. Bracts lanceolate, with a long
setaceous point, caducous. Flowers white tinged with rose-color, inodorous.
Legumes linear-lanceolate. 2-3 inches long.— Clammy Locust.—R. dubia,
Desv. jour. bot. {DC. 1. c.) is doubtless, as De Candolle suspects, a garden
hybrid between this species and R. Pseudacacia.

twice the size of those of R. Pseudacacia, deep rose-color, inodorous.—The
R. hispida, var. rosea of Elliott is said to have spiny stipules, and the branch-
lets, petioles, and lower surface of the leaves pubescent. Can it be a form of
R. viscosa ?
19. TEPHROSIA. Pers. syn. 2. p. 328; DC. prodr. 2. p. 248.
Calyx without bracteoles, about equally 5-toothed or 5-cleft. Vexillum
large, roundish, spreading or reflexed, usually silky or pubescent on the outside:
keel obtuse, cohering with the wings. Stamens monadelphous or
sometimes diadelphous; the tenth filament sometimes half united with the
others. Style filiform, bearded longitudinally, or glabrous: stigma terminal.
Legume commonly sessile and much compressed, linear, many-seeded ;
valves usually flat. Seeds compressed.— Shrubby of herbaceous plants,
erect or procumbent, silky-villous. Leaves unequally pinnate (rarely reduced
to a single leaflet). Stipules free from the petiole, lanceolate or subulate,
never sagittate. Racemes terminal or opposite to the leaves, or axillary.
Flowers white or purplish.
The North American species are all herbaceous plants; with the lobes of the
calyx broad at the base and acuminated; the style longitudinally bearded on the
inside ; and the legumes more or less hispid, villous, or velvety: they belong to the
section Brissonia, DC. ■ but the stamens are mostly diadelphous.
