of the juicy drupe which contains 2 nutlets, salverform corolla, and 2 
stigmas. 
1, C. villosum Jacq. Soft-pubescent or glabrate: leaves oblong-obovate or ob- 
long, entire or occasionally few-toothed above the middle, veiny and with finely 
reticulated veinlets, shining and barely scabrous above, pale and somewhat soft: 
canescent beneath, biglandular at the narrowed base, tapering into the petiole: 
racemes declining, loose, but spike-like: corolla white, glabrous externally.—South- 
ern Texas and Mexico. 
2. C. brachyanthum Gray. Puberulent: leaves from linear-spatulate to obovate, 
6 to 12 mm. long, veinless, subsessile: flowers solitary or subsolitary in the center 
of axillary fascicles of leaves (which are remarkably small): tube of white corolla 
barely surpassing the calyx. (Lycium brachyanthum Gray in Hemsl.) Southern 
borders of Texas, at Laredo. 
6. DURANTA L. 
Like the last, but calyxin fruit ampliate and inclosing the drupe 
which contains 4 nutlets (hence 8 seeds), corolla commonly curved, and 
stigma unequally 4-lobed. 
1. D. Plumieri Jacq. Minutely pubescent or glabrate: leaves obovate, oblong, 
or ovate, mostly entire, contracted at base into short petiole: racemes panicled, 
loose; lower bracts often leafy: corolla lilac: drupe yellow, the inclosing persistent 
calyx also yellow, closed into a straight or contorted beak.—Brazos Santiago (Neal- 
ley). 
7. CALLICARPA L. 
Shrubs, with scurfy pubescence, small flowers in axillary cymes, 4 or 
2-toothed short calyx, tubular-bell-shaped 4 or 5-lobed nearly regular 
corolla, 4 nearly equal exserted stamens, anthers opening at apex, 
slender style thickened upward, and fruit a small berry-like drupe with 
4 nutlets, 
1. C. Americana L. (FRENCH MULBERRY.) Leaves ovate-oblong with a taper- 
ing base, acuminate, toothed, whitish beneath: cymes many flowered: calyx ob- 
scurely 4-toothed: corolla bluish: fruit violet-color.—Rich or moist grounds, ex- 
tending from the Gulf States to southern Texas. 
LABIATH. (MinT FAMILY.) 
Chiefly herbs, with square stems, opposite aromatic leaves, more or 
less 2-lipped corolla, didynamous or diandrous stamens, and a deeply 
4-lobed ovary which forms in fruit 4 little seed-like nutlets or achenes 
surrounding the base of the single style in the bottom of the persistent 
calyx. 
I. Nutlets rugose-reticulated: ovary merely 4-lobed. 
Tribe I. Stamens 4, ascending and parallel, mostly exserted from the upper side 
of the corolla: calyx 5 to 10-nerved. 
* Limb of corolla merely oblique, of 5 nearly equal and similar lobes. 
1. Tetraclea. Calyx regular: corolla-lobes similar and equally spreading: sta- 
mens exserted. 
2. Trichostema. Calyx oblique: corolla lobes all declined: stamens exserted. 
3. Isanthus. Calyx bell-shaped: corolla small, the lobes spreading: stamens in-
