cieled in the axils, the root is annual, and the sepals are less strongly nerved
and less rigid than in A. stricta.
11. A. Pitcheri (Nutt.! mss.): “ erect and slender, glabrous, fastigiately
branched, few-flowered; leaves linear-filiform, obtuse, not fascicled ; peduncles
slightly glandular-pubescent; petals oblong, somewhat exceeding [nearly
twice the length of] the lanceolate strongly 5- [sometimes .3-] nerved sepals.”

Plains of Arkansas, Nuttall! Dr. Pitcher! Texas, Drummond ! Dr.
Leavenworth !—(J) Stem 3-6 inches high, with filiform branches. Leaves
very narrow but flat.—Nearly allied to A. patula, and also to A. tenuifolia of
Europe, as Mr. Nuttall very correctly remarks.
12. A. patula (Michx.): branched from the base, diffuse; forks of the
cyme divaricate ; leaves linear, very narrow, obtuse, spreading; petals spa-
tulate, emarginate, twice the length of the lanceolate very acute 3-5-nerv-
ed sepals.—Michx. ! jl. 1. p. 273; DC. prodr. 1. p. 405.
On rocks, Kentucky, Dr. Short! and mountains of Virginia, Prof. Ruff-
ner !— (T) (©'? ) Stems weak, almost filiform, 6-10 inches long, glabrous
to the naked eye, but minutely glandular-pubescent under a lens. Cyme 4 or
5 to 20-flowered, much spreading: pedicels almost setaceous. Leaves often
slightly fascicled in the axils.
13. A. glabra (Michx.): csespitose, glabrous; stems filiform, decumbent
at the base, 8- 12-nowered; leaves linear-setaceous, spreading; branches of
the cyme and very slender pedicels divaricate ; petals obovate-oblong, twice
the length of the oval, obtuse, membranaceously-margined, nerveless sepals.—

“ Table Rock, Alabama,” herb. Schweinitz !—2f Plant growing in dense
grass-like tufts : stems very slender, and commonly branched above, about 6
inches high. Leaves nearly half an inch long, almost setaceous. Pedicels
elongated, setaceous. Flowers smaller than in A. patula and A. Groenlan-
dica.—This little known species appears to be confined to the more or less
mountainous portions of the Southern States ; the A. glabra of Elliott, growing
in the low country being evidently Stellaria uniflora, Walt.
14. A. Grcenlandica (Spreng.): caespitose, glabrous; stems low, decumbent
at the base, 1-5-flowered; leaves very narrowly linear, obtuse; pedicels
filiform, nearly erect; petals obovate-cuneiform, entire or with a slight notch,
twice the length of the rather oblong, very obtuse, membranaceously margined,
nerveless sepals.—Spreng. syst. 2. p. 402. Stellaria Groenlandica,

about 3 (rarely 5) inches high. Leaves almost subulate, but obtuse, 3-5
lines long, erect or spreading. Flowers large for the size of the plant, larger
than those of A. glabra. Lobes of the disk from which the stamens arise
slightly thickened and glandular.—The identity of our plant with Stellaria
Grcenlandica, first suggested by Dr. Pickering, is confirmed by a specimen
from Greenland in herb. Schweinitz, so named by Vahl.
15. A. brevifolia (Nutt.! mss.) : glabrous, not csespitose ; stems filiform,
erect, simple, 2-5-fiowered; leaves minute, erect (many times shorter than
the internodes), lanceolate-subulate, nerveless ; sepals oblong, obtuse, with
scarious margins, about the length of the 3-valved capsule; petals obovate-
