mentose-pubescent beneath, petioled: peduncles mostly solitary in the axils, hardly 
longer than the petiole: head globular, at length cylindraceous: bracts broadly ovate, 
abruptly cuspidate-acuminate, villous-canescent, a little shorter than the purple or 
violet corolla. (ZL. geminata HBK.)—Southern Texas, along the Rio Grande to Brazos 
Santiago. 
+++ Herbaceous, procumbent or creeping : peduncles chiefly axillary aud slender: calyx 
strongly flattened. 
5, L. nodiflora Michx. Creeping extensively, cinereous or greenish: leaves cuneate- 
spatulate or oblanceolate, sessile or nearly so, obscurely veiny or almost veinless, the 
long tapering base entire, sharply serrate from above the middle to the apex: pe- 
duneles filiform, much exceeding the leaves: corolla rose-purple or nearly white.— 
Low grounds, extending from the Gulf States to western Texas. 
6. L, lanceolata Michx. Like the last, but greener, minutely and sparsely strig- 
ulose: leaves thinner, mostly broader, varying from obovate and Janceolate-spatu- 
late to ovate, narrowed at base mostly into a petiole, above sharply serrate, pin- 
nately straight-veined: corolla bluish-white.—River banks, extending from the At- 
lantic region to western Texas. 
4. LANTANA L. 
Like the last, but with very small truncate or sinuate-toothed calyx 
merely surrounding the base of the fleshy or juicy drupaceous fruit, 
and limb of corolla not 2-lipped. 
* Drupe thin-fleshed or somewhat dry, at least with nutlets contiguous and usually coher- 
ing more or less into a 2-celled stone: stems never prickly. 
1. L. involucrata L. Canescent: leaves obovate-oval or ovate, rounded at apex, 
crenate, rugulose and veiny, scabrous above, soft-tomentose beneath, cuneate at 
base, rather slender-petioled: peduncles equaling or exceeding the leaf: bracts silky, 
the outermost as long as the white or lilac flowers and forming an involucre. (L. 
odorata, var. Berlandiert Torr. Mex. Bound )—Southern borders of Texas. 
2. L. macropoda Torr. Cinereous with minute strigulose puhescence: leaves 
ovate or oblong-ovate, acute, coarsely and sharply serrate, obtuse or somewhat 
cuneate at base, petioled, usually scabrous above and slightly canescent beneath, 
not at all rugose-reticulated, the primary veins conspicuous and running straight to 
the sinuses: peduncles twice or thrice the length of the leaf: bracts nearly equaling 
the white or purple corolla, the outermost gradually larger but hardly forming an 
involucre.—Southern and western Texas. 
** Drupe juicy, the 2 nutlets separated, at least at base: stems sometimes prickly or his- 
pid. 
3. L. Camara L. Scabrous and more or less hirsute, 3 to 12 dm. high: leaves ovate 
or obvate-oblong, often subcordate, crenate-serrate, very scabrous above, scabrous- 
hirsute or softer-pubescent beneath: peduncles rigid, about the length of the leaf: 
bracts strigose-hirsute, about half the length of the yellow at length orange or even 
flame-colored corolla.—Extending from the Gulf States through southeastern Texas 
to tropical America. “Low bush, with dark green foliage and handsome golden- 
orange flowers, considered poisonous to sheep and cattle in southeastern Texas. Itis 
noticed they always shun it, even where grass is scant.” (Havard.) 
5. CITHAREXYLUM L. 
Shrubs or trees, with somewhat coriaceous leaves, small flowers soli- 
tary or on a filiform rhachis each subtended by a minute bract, calyx 
with truncate minutely 5-toothed border and in fruit girting the base
