444 XCIX. SOLANACEZ. 
2. C. Sepium. Br. (Convolvulus. Linn.) Hedge Calystegia. Rutland 
Beauty.— St. twining ; lvs. sagittate, the lobes being truncate and the apex 
generally acute; ped. quadrangular, 1-flowered; bracts cordate, much longer 
than the calyx.—2 A vigorous climber, in hedges and low grounds, Can. to 
Car., W.to fll. Stems 5—8f in length. Leaves cordate-sagittate,2—4 long, 
4 as wide. Flowers numerous, large, white, with a reddish tinge, appearing 
in long succession. The bracts are so close to the corolla as to appear like the 
calyx which they entirely conceal. It is cultivated as a shade for windows, 
arbors, &c. June, July. 
SuporperR 2. CUSCUTEX. 
Embryo without cotyledons. Leafless, parasitic herbs. 
5. CUSCUTA. Tourn. 
Calyx 5 (rarely 4)-cleft; corolla globose-campanulate, 4—5-cleft, 
marescent ; stamens 4—5, inserted upon the corolla at the clefts; 
stigmas, 2 ; capsule 2-celled, circumscissile at the base ; cells 2-seeded. 
—Herbs without verdure, germinating in the soil, at length withering at 
the root, and deriving their nourishment from other plants about which 
they twine from right to left. Stem yellowish or reddish. Leaves none, 
or minute scales instead. ls. variously aggregated. 
1. C. Gronovi. Willd. (C. Americana. Linn. C. vulgivaga and sau- 
ruri. Eng.)—St. filiform, thick; fls. densely glomerate, in paniculate 
spikes, sessile ; sep. broad-ovate, obtusish ; cor. 5-cleft, segments short, spread- 
ing or reflexed, withering at the base of the capsule; scales oblong, fimbriate ; 
sty. diverging; stig. capitate—@ An extremely delicate vine, found in damp 
places, by rivulets, Can. and U.S. The stem is smooth, slender, 3—5f long, 
springing from the soil at first, but after having twined itself about the low 
plants in its way, and becoming fixed upon them by its lateral radicles, it with- 
ers away at base, and is henceforth disconnected with the soil. It is of a light 
orange color, wholly destitute of green, furnished with a few minute scales, 
branching, always turning from right to left, or hanging in festoons. Flowers 
nearly globose, about a line long, and on peduncles of about the same length. 
Calyx segments round-obtuse. Corolla twice as long, yellowish-white. Aug. 
2. C. LepipancHe. Wood. (C. glomerata. Choisy. Lepidanche composi- 
tarum. Engelm.)—St. filiform; fls. in compact masses surrounding the 
stem, sessile, with scarious bracts intermixed; cal. 5-sepaled, scarious; cor. 
tubular-campanulate, 5-lobed, longer than the calyx, lobes lanceolate, acute, 
spreading or reflexed ; anth. elongated; scales fimbriate—@ Abundant in Mo., 
fil.! and la.! on the Labiates, composites, &c. Flowers about 2” long, form- 
ing compact, cylindrical masses while the stems decay, appearing as if spring- 
ing from the stems of other plants. Corolla white and scarious. Anthers 
partly exserted. July. 
8. adpressa. Chois. (Lepidanche adpressa. Eng.) Bracteate; sep. obtuse 
or orbicular-ovate.—I]l. 
3. C. EpiLinum. Weih. (C. Europea. Darl. & others.) Flax Dodder.— 
Fis. sessile, in small, dense, remote heads; cal. 5-parted, segments rather 
obtuse; cor. globose-cylindric, scarcely longer than the calyx, withering around 
the capsule; scales minute, crenate-dentate——@ Europe, introduced into the 
Mid. States, growing on flax. Tvrr. Darl. Stems reddish-orange. Flowers 
yellowish-white. Calyx thickish; stamens included. Stigmas acute. Cap- 
sule depressed-globose, surrounded with the withering corolla. June, 
Orpver XCIX. SOLANACE A#.—NicutTsHanes. 
Plants herbaceous or shrubby, with a colorless juice. Lvs. alternate, the floral ones sometimes collateral. 
Inflorescence often supra-axillary ; pedicels bractless. 
Cal.—Sepals 4—5, more or less united, mostly persistent. 
Cor. regular, limb 4—-cleft, plaited in estivation, deciduous. — — 
Sta. 4—5 (sometimes 1 abortive), inserted on the corolla, alternate with its segments.
