late tufts, somewhat coriaceous; the caulme pairs rather few and distant

Capsule about half free ; the cells 8-9-seeded.
7. H. longifolia (Hook.): glabrous; stems erect, 4-angled with decurrent
lines; leaves linear or oblong-linear, acute or. obtusef tapering to the'
base, 1-nerved; the radical ones oval or oblong, narrowed into a petiole;
cymules 2-3-flowered, somewhat paniculate; the pedicels at first short, at

June-July.—Stems 6-10 inches high, usually numerous from the same root,
obscurely 4-sided, but with the angles; or 2 of them, margined with very
narrow sharp decurrent lines. Leaves 9-15 lines long, 2-3 lines broad, glabrous,
or the margins very slightly scabrous. Stipules scarious, small, ovate
or triangular. Flowers rather smaller than in the preceding, pale purple or
nearly white. Corolla much longer than the lobes of the calyx. Capsule
nearly half free ; the cells about 10-seeded. Stamens and style varying inversely,
as in the preceding species.—This is probably distil,ct from H. purpurea,
the narrow-leaved forms of which sometimes approach it very nearly;
although the length of the calyx-lobes is perhaps not absolutely invariable.
It seems to pass insensibly into the H. tenuifolia, Nutt. ; which is, however,
a remarkably slender plant, with more distant narrowly linear leaves, and
very slender and spreading branches and pedicels, the latter several times
longer than the (about 8-seeded) fruit.
8. H. stenophylla: slightly suffruticose at the base, glabrous ; stems erect
or assurgent, much branched; leaves very narrowly linear, often with
smaller ones fasciculate in the axils, 1-nerved, acute, tapering to the base ;
flowers very numerous, in 3-4 times di-trichotomous cymules, corymbose at
the extremity of the branches; pedicels short, the central flower of each
cluster almost sessile ; lobes of the .calyx subulate, as long as the tube ; capsule
turbinate.—Houstonia angustifolia, Michx.! f t 1. p. 85. (not Hedyotis

Banks of rivers, and prairies; sea-coast of Florida, Michaux ! (Georgia?
Elliott!) to Kentucky! Missouri! Louisiana! Arkansas! and Texas! June-
July.—Stem 10 inches to 2 feet high. Leaves an inch or more in length.
Flowers very numerous, usually fastigiate-corymbose, pale purple : the tube
of the corolla thrice the length of the calyx-teeth (which are furnished with a
few very minute bristly hairs); the oblong segments and throat very villous
inside. Filaments and style either exserted or included inversely, as in the
other species of the section. Capsule small, acute at the base ; the summit
only free. Seeds 5-10 in each cell, oval, black.—Readily distinguished by
its turbinate fruit. In the other species of this section, the pedicels (2-7) are
equal or nearly so, and more or less elongated in fruit: in this, the central
flower of each cymule is nearly sessile.
§ 3. Corolla rotate, much shorter than the lanceolate teeth of the calyx, which
are spreading and with, the sinuses acute in fr u it: stamens and style very
short: anthers roundish-ovate : capsule ovoid, wholly coherent with the tube
of the calyx, loculicidally dehiscent across the summit: seeds very numerous
and minute (50-60 in each cell), angular : herb perennial, with the habit of
Spermacoce or Diodia : stipules mostly bimucronate or bisetrtse on each side :
flowers solitary or 3-4 together in the axils of the leaves, almost sessile.__

9. H. Boscii (D C .): herbaceous, or suffruteseent at the base, much
branched, diffuse, glabrous; branches slender; leaves linear, acute at each
end, obscurely 1-nerved; stipules very small; flowers on very short pedicels
; teeth of the calyx triangular-subulate, spreading or recurved, shorter
