Borders of ponds and streams, and in open grounds, Carolina (Bose!) to
Louisiana, Tainturier ! Drummond ! Dr. Carpenter ! Alexandria, Dr. Hale !
and on the banks of the Sabine, Dr. Leavenworth ! July-Sept._Stems 6-
10 inches long. Leaves about an inch in length. Flowers minute; the
fruit scarcely more than a line long, minutely scabrous, crowned with the
rather short calyx-teeth. Corolla (purplish, Leavenworth,) with scarcely any
tube. The plant turns blackish in drying.—Somewhat intermediate between
the sections Scleromitrion & Oldenlandia of Wight & Arnott.
§ 4. Corolla rotate, much shorter than the teeth o f the calyx, which are erect in
fruit, with the sinuses acute : stamens scarcely longer than the lobes of the
corolla: anthers sub globose: style nearly none: stigmas oblong, obtuse:
capsule globose-compressed, wholly coherent with the tube of the calyx,
emarginate, loculicidally dehiscent across the summit: seeds very numerous
and minute (60 or more in each cell), angular: herb annual, with the habit
of Elatine : stipules bisubulate on each side: flowers solitary or mostly
glomerate in the axils o f the leaves.—11 lati.n et.j.a.
This and the preceding sections should probably be considered mere divisions of
the subgenus Oldenlandia, whenever that group shall be definitely characterized.
10. H. glomerata (Ell.) : stems diffuse or somewhat erect, hirsute-pubescent,
branching: leaves oblong or elliptical-lanceolate, narrowed at the
base, or slightly petioled, nearly glabrous ; flowers mostly glomerate in the
axils ; tube of the calyx hirsute, shorter than the ovate or oblong fbliaceous
lobes.—Ell. sk. 1. p. 187 ; Torr. ! fl. 1. p. 171; DC. ! prodr. 4. p. 421.

Margin of swamps, and especially brackish marshes, New York! and
New Jersey! to Florida! and Louisiana! June-Oct.—Stem 2-18 inches
high. Leaves half an inch to an inch long, often slightly pubescent, somewhat
3-nerved at the base, slightly veiny. Stipules on each side cleft nearly
to the base into 2 subulate divisions, which are as long as the petioles or
narrowed base of the leaves. Flowers small, seldom solitary or three together,
and then pedicellate, usually in small dense clusters. Corolla many
times shorter than the limb of the calyx, white; the lobes semiovate. The
plant does not turn blackish in drying.
§5. (An gen.?) Flowers pentamerous: corolla infundibuliform, b-lobed,
somewhat longer than the 5 lanceolate-subulate teeth of the calyx, which are
erect in fruit, with the sinuses obtuse; stamens 5, included, inserted towards
the base o f the corolla : anthers oblong: style as long as the stamens : capsule
turbinate, wholly coherent with (and rather shorter than) the tube of the
calyx, loculicidal at the summit: placentee pedicellate from the middle o f the
septum, horizontal: seeds very numerous, angular: herb perennial, dichotomous
: stipules 2—1-subulate on each side : flowers axillary, somewhat cym-
ulose.—P e n to t is . 1
11. H. Halei: glabrous; stem diffuse, dichotomous; leaves oval-oblong,
somewhat fleshy, rather acute, narrowed into a slight petiole; cymules 3-5-
flowered, scarcely pedunculate; shorter than the turbinate capsule.
Red River, near Alexandria, Louisiana, Dr. Hale!—Stems 8-10 inches
long, branched from-the base. Leaves an inch to an inch and a half long,
half an inch broad, shining underneath. Stipules broad, connate with the
petioles, membranaceous, truncate, with 2-4 short subulate appendages on
each side. Pedicels scarcely longer than the calyx. Corolla white, about
twice the length of the calyx-teeth. Lobes of the stigma linear-oblong,
hairy. Seeds minutely roughened.—This plant appears to accord with
Hedyotis (Oldenlandia), except in its pentamerous flowers.
Houstonia grandiflora, pusilla, & ciliata, Raf. morwgr. Houst., in ann. sci. gen.
1820, (his subgenus Edrissa, which corresponds to Houstonia proper,) are doubtless
synonyms of H. cærulea. Houstonia obtusifolia, oblongifolia, and heterophylla,
Raf. I c. belong doubtless to H. longifolia and H. ciliolata.
S ubo rder III. LOGANIEiE. R . B r. (Loganiacese, Lindl.,
Endl. in part.)
Leaves opposite. Stipules between the petioles, sometimes nearly
obsolete. ^Estivation of the corolla valvate or convolute. Ovary free
from the persistent calyx, or nearly so.—Shrubs or herbs, natives of
warm or tropical regions.
In thus appending Logania and its nearest allies to Rubiacese (which seems inevitable
when we compare Ophiorhiza with Mitreola, a portion of Hedyotis with
Ccelostylis, &c.), we trust we-are following the indications thrown out by the most
profound botanist who proposed the order or tribe (Appx. to Flinders, 2. p. 564, and
Tuckey’s Congo, p. 448); although it is still no less true than when Mr. Brown
first made the remark, that there are no satisfactory characters known to distinguish
Rubiacese from Apocynaceae.
17. CCELOSTYLIS. Torr. Gr., in Endl. decad., Sf iconogr. t. 101.
Calyx deeply 5-parted. Corolla infundibuliform ; the limb 5-cleft, valvate
in aestivation, the margins slightly reduplicate. Stamens 5, inserted
near the middle of the tube, included: anthers oblong-linear. Ovary 2-
celled, free from the calyx, seated on a small 2-lobed disk: ovules 10 or
more in each cell, peltate, covering the somewhat projecting placentae, which
arise from near the base of each cell: style included : the lower portion solid,
persistent; the upper half membranous, tubular, deciduous by an articulation
; the summit cylindrical-subclavate, villous with rigid collecting hairs:
stigma undivided. Capsule didymous, composed of two subglobose rather
coriaceous carpels, which at length separate from each other and from the
indurated disk, opening elastically by loculicidal dehiscence. Seeds 6-8 on
each globose placenta, wingless, angular, scrobiculate. Embryo nearly
the length of the fleshy albumen, almost straight: cotyledons oblong.__Herbaceous,
probably perennial plants (natives of Florida and Texas), with
somewhat angular stems. Leaves opposite, ovate or oblong-lanceolate,
somewhat veined, slightly petioled, with small entire stipules between the
petioles. Flowers small, solitary or somewhat cymulose, axillary, dichoto-
mal, and terminal.
