Calyx-tube obovate ; the limb 5-toothed. Corolla with a long terete tube.,
the segments of the 5-parted limb linear, revolute, valvate in aestivation.
Stamens 5, inserted into the corolla near the base, much exserted : anthers
narrowly linear. Style filiform, clavate at the summit: stigma entire or
somewhat 2-lobed. Capsule coriaceous, opening at the summit by septici-
dal dehiscence. Seeds flat, with a circular winged margin, retrorsely imbricated.—
Trees or shrubs of tropical America, (the bark febrifugal or-somewhat
emetic; but destitute of Quinia and Cinchonia, according to St.
Hilaire), usually glabrous. Stipules one op each side. Pedunclesaxillary

Key West, Mr. Blodgett!—A glabrous shrub. Leaves li- 2 inches long,
somewhat coriaceous. Stipules broad and very short, with a subulate point.
Flowers crimson, odorous, showy. Pedicels half an inch long. Calyx-teeth
rather acute. Corolla nearly 2 inches long; the tube about the length of the
linear segments. Anthers half an inch in length and very slender. Style
much exserted : stigma entire.—The bark of this plant is used in the West
Indies as a substitute for Cinchona bark.
15. P-INCKNEYA. Michx.fl. 1. p. 103, t. 13; A . Rich. mem. 1. c. p. 277.
Calyx-tube oblong-turbinate; four of the segments of the deciduous 5-
parted limb linear-lanceolate, the fifth usually dilated into a large colored
leaf. Tube of the corolla cylindrical; the lobes' of the 5-parted limb linear-
oblong, recurved-spreading, somewhat imbricate ip aestivation. Stamens 5,
inserted into the corolla near the base, exserted : anthers oblong. Style filiform
: stigma obtusely 2-lobed. Capsule subglobose, coriaceo-chartaceous,
2-valved, loculicidal. Seeds numerous, horizontal, in a double series, flat,
with a reticulated membranaceous wing. Embryo large, straight: cotyledons
foliaceous, concave.—A large shrub or small tree; the young branches
&c., hirsute-tomenlose. Stipules one on each side, linear-subulate, caducous.
Flowers large, in small cymes, which are terminal or in the axils of
the upper leaves. Corolla purplish inside, hirsute-canescent externally.

Swamps, S. Carolina! to Middle Florida! May-June.—Stems or trunks
often clustered. Leaves oval, ac.ute or acuminate at both ends, on short petioles,
nearly glabrous above, pubescent or somewhat tomentose beneath, 4-
8 inches long, and 3 or 4 broad. Limb of the' calyx somewhat colored ; one
(or sometimes two) of the segments dilated into an oval membranaceous
(rose-colored) petioled leaf, two or three inches in length. Corolla an inch
and a half long; the segments shorter than the tube. Capsule about half an
inch in diameter ; the dehiscence loculicidal and at length partly septicidal
also.—-This genus is doubtless sufficiently distinct from Musstenda, to which
Jussieu joined At, and with which it accords in habit. The bark has the
taste and medicinal properties of Cinchona, and probably contains the same
or a new alkaline principle.
T r ib e V I , HEDYOTLDE2E. Cham. Schlecht.
Fruit capsular, 2-celled, usually loculicidal (rarely somewhat membranaceous
and indehiscent) ; the cells several-many-seeded. Seeds
wingless. Albumen fleshy. ^Estivation of the corolla mostly imbricated
or contorted.—Herbs or shrubs. Stipules between the petioles,
either one or two on each side, or frequently united with the petioles
into a membranaceous sheath, which is often fringed with bristles, as in
Spermacocese.

Hedyotis, Houstonia, Ss Oldenlandia, Linn,—Anotis &e., DC,
Calyx-tube ovate or globose; the limb 4- (rarely 5- ?) toothed or cleft,
persistent. Corolla infundibuliform, hypocrateriform, or rotate, 4- (rarely
5- ?) lobed; the lobes imbricate in estivation. Stamens as many as the
lobes of the corolla, inserted either in the throat or towards the base of the
tube. Stigma usually 2-cleft or 2-lobed. Capsule globose, ovoid, or obcor-
date, mostly coriaceous, the summit often free from and exserted beyond the
calyx, 2-celled, opening across the summit by loculicidal dehiscence, and at
length often slightly septicidal. Seeds few or numerous, on placental (either
ascending or horizontal) which project into each cell, with a reticulate-punctate
or scrobiculate testa.—Herbs, or suffruticose plants. Stipules connate
