MONOGRAPHY OF THE NORTH AMERICAN CUSCUTINE. 67 
cymes umbelliform, compound ; flowers peduncled (small), 5-parted ; calyx campanulate, verrucose ; segments 
ovate, somewhat obtuse, shorter than the globose-campanulate tube of the corolla; lobes of the entolle long- [75] 
acuminate, somewhat longer than the tube ; stamens half as long as the limb; scales ovate fimbriate, rather 
larger than the tube ; ovary globose, depressed, without stylopodium; capsule depressed. — The tissue of the corolla is 
composed of large irregular cells 
6. CUSCUTA HISPIDULA, n. sp.: stem low; cymes loose, few-flowered, hairy or nearly smooth ; flowers very 
long peduncled (small), 5-parted ; tube of the corolla turbinate-campanulate, twice the length of the ovate subacute 
segments of the calyx, shorter than the long-acuminate somewhat crenulate spreading lobes ; stamens half as long as the 
limb ; scales ovate, fimbriate, nearly equalling the tube ; ovary with a stylopodium and short styles. 
Texas, in dry and sterile prairies west of Houston. Flowering in April and May. Compare the remarks made 
in Vol. XLIIT. p. 341, under C. verrucosa. 
7. CUSCUTA NEUROPETALA, n. sp.: cymes umbelliform, smooth, flowers pedunculate (large), 5-parted ; tube of 
the corolla campanulate, nearly equal in length to the ovate-lanceolate acute carinate segments of the calyx, and the 
ovate short-acuminate one-nerved crenulate spreading lobes ; stamens rather shorter than i: limb ; scales ovate, fim- 
briate, incurved, as long as the tube ; styles rather longer than the ovary with the stylopodiu 
exas, in wet prairies near Houston ; on different Composite, such as Liatris, Solidago, Helianthtil Rudbeckia, 
and on Myrica cerifera; flowering in August ; F. Lindheimer 
Flowers rather large, but vaeaies in size ; segments of Giyx always very acute, ovate or ovate-lanceolate, some- 
what shorter or a little longer than the tube of the eoeolla. Anthers yellow or purple ; stigmas purple. 
This and the last species resemble in the structure of the corolla the more northern C. Coryli; they have the 
same crenulated margin, the same fleshy-cellular texture, similar incurved tips of the acute lobes, and the same white 
color, which is not altered in well-dried specimens. 
neuropetala is distinguished from C. hispidula by its perfect smoothness, its flowers being twice or three times 
as large, its more compact, umbelliform cymes ; the whole plant is taller (in my specimens twelve to eighteen 
inches high). The calyx segments, at least the three outer ones, are carinate ; the lobes of the corolla are [76] 
broader, shorter, composed of small linear cells, which are contracted in the middle into a distinct nerve. Stylo- | 
podium large in proportion to the ovary. Capsule not seen. The purple anthers and stigmas in the white flowers, 
give this species a very pretty appearance.

8. CuscuTA PENTAGONA. — Capsule globose, somewhat depressed, without a pee ian - description is 
taken from the Virginia plant; the forms from Illinois and Texas constitute two distinct vari 
. MICROCALYX: flowers shorter peduncled ; calyx not remarkably 5-angled, much shorter sia ‘the tube of the 
corolla, — Illinois. 
y. CALYCINA: flowers shorter omg calyx not remarkably 5-angled, longer than the tube of the corolla, 
which is equal to the acute lobes. — Tex 
This species bears some psec? ea to 0 . Polygonorum on one side, and to the three foregoing species on the other; 
to these by the acuminate lobes of the corolla, to the first by the depressed ovary and pale greenish-yellow capsule ;1 
but it is distinguished from both by the orbicular lobes of the generally large and more or less pentagonal calyx. The 
inflorescence represents little umbels in a. or approaches the glomerules of C. Polygonorum in B. andy. The lobes of the 
corolla are acute, resembling in shape those of the following species, in the Texan variety; or longer and finely acuminate 
(similar to C. verrucosa and 0. hispidula), in the more northern forms. Stamens short, only half the length of the limb; 
anthers nearly globose. Scales large, ovate, fimbriate, sometimes exceeding the tube. Ovary and capsule depressed. 
This is probably the earliest species in North America ; in Texas it has been found in bloom in April and May, 
and near Bardstown early in July ; while here, one hundred miles further south, hardly any other species begins to 
open its flowers before the last days of that month. 
9. Cuscuta Poryaonorum. — Segments of calyx generally as long as the tube of the corolla, mostly subacute, 
but occasionally also somewhat obtuse ; the corolla is thin, membranaceous, composed of a very fine cellular tissue ; 
stamens broad at base, subulate ; scales smaller than any other species, except C. Coryli. 
II. LEPIDANCHE. 
Last autumn I discovered a second species of this genus, which imposes the necessity of altering the generic 
character. It must now read: Capsule 2-celled, 1—4-seede 
The facies of the genus refers principally to the first ecicn the second has more the appearance of a Cuscuta, 
but the flowers are also closely sessile. 
1 In all other species which are here mentioned, it is of a brown color, except perhaps in C. Cephalanthi, where it is also 
light-colored.
