b. Obtuse lobes of corolla spreading. 
5. C. Gronovii Willd. Stems coarse, often climbing high: corolla-lobes mostly 
shorter than the deeply campanulate tube: scales copiously fringed: pod globose, 
umbonate.—The most common Atlantic species, and exte nding into Texas. In 
Louisiana and Texas occurs var, CALYPTRATA Engelm., distinguished by the corolla 
eventually capping the pod. 
++ ++ Calyx of 5 distinct and largely overlapping sepals, surrounded by 2 to 5 or more simi- 
lar bracts: scales of corolla large and deeply fringed: pod mostly 1- seeded, capped 
by marcescent corolla. 
= Flowers on bractcolate pedicels, in loose panicles, 
6. C. cuspidata Engelm. Stems slender: flowers 3 to 4.5 mm, long, thin, mem- 
branaceous when dry: bracts and sepals ovate-orbicular and oblong: lobes of corolla 
cuspidate or mucronate, rarely obtuse, shorter than the cylindrical tube: styles many 
times longer than ovary, at length exserted.—Wet or dry prairies, throughout Texas 
and northward. On Ambrosia, Iva, some Leguminose, ete. 
= = Flowers closely sessile in densely compact clusters, 
Bracts and sepals concave and appressed. 
7. C. squamata Engelm. Orange-colored stems slender: glomerules few-flowered, 
often contiguous: tlowers white, membranaceous when dry, 5 to 6 mm. long: cuspi- 
date or obtuse sepals and lanceolate acute corolla-lobes both shorter than the eylin- 
drical upwardly widening tube: styles many times longer than oy ary.— Western 
Texas. Common in bottom lands of Upper Rio Grande. 
8. C. compacta Juss. Stems coarse: tlowers (about 4 mm. long) at length in con- 
tinuous and often very thick clusters: orbicular bracts and sepals crenulate, nearly 
equaling or shorter (and ovate-oblong lobes much shorter) than the cylindrical 
corolla-tube: styles little longer than ovary.—In damp woods, extending from the 
Atlantic region to Texas. Almost always on shrubs. 
b. Bracts (8 to 15) and sepals with recurvet-spreading and crenate tips, 
9. C. glomerata Choisy. Stems coarse, orange-colored, soon withering away, 
jeaving dense flower-clusters closely encircling in rope-like masses the stems of the 
host: sepals nearly equaling and its oblong obtuse lobes much shorter than the 
cylindrical upwardly widening corolla-tube: styles several times longer than ovary.— 
Wet prairies, extending from the north into Texas. Mostly on Helianthus, Vernonia, 
and other tall Composite. 
+ + Capsule more or less regularly circumscissile, usually capped by remains of corolla: 
styles capillary and mostly much longer than the depressed ovary. 
10. C. leptantha Engelm. Stems low and capillary: flowers (4 to 4.5 mm. long) 
4-merous, on slender fascicled pedicels: papillose calyx and lanceolate corolla-lobes 
much shorter than the slender tube: scales incisely dentate and much shorter than 
tube.—Mountains of western Texas, on a prostrate Euphorbia ( Wright). 
11, C. umbellata HBK. Stems low and capillary: flowers (3 to 5 mm, long) few 
together in umbel-like clusters, shorter than their pedicels: acute calyx-lobes and 
lanceolate-subulate corolla-lobes larger than its shallow tube, the latter soon sharply 
reflexed: scales deeply fringed and exceeding the tube: styles mostly little longer than 
ovary. (C. Californica, var. refleca Coulter.)—Dry places, southern Texas. On low 
herbs. 
** Styles united into one: capsule circumscissile. 
12. C. exaltata Engelm. Stems thick, climbing high: lobes of fleshy calyx and 
corolla orbicular, the former covering and the latter half the length of the corolla- 
tube: anthers sessile: scales small, bifid or reduced to a few lateral teeth: styles 
two-thirds united.—Southern Texas, from the Colorado to the Rio Grande. On trees, 
such as Diospyros Texana, Ulmus crassifolia, Live Oak, etc.
