nulate tube of the corolla; lobes of the corolla long 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. Cuscura HISPIDULA, 2. 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 equaling 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. xii, p. 
341, under C. verrucosa. 
7. CuscUTA NEUROPETALA, 7. sp.—Cymes umbelliform, smooth, 
flowers pedunculate (large), 5-parted ; tube of the corolla campa- 
nulate, nearly equal in length to the ovate-lanceolate acute cari- 
nate segments of the calyx, and the ovate short-acuminate one- 
nerved crenulate spreading lobes; stamens rather shorter than 
the limb; scales ovate, fimbriate, incurved, as long as the tube; 
styles rather longer than the ovary with the stylopodium. 
Texas, in wet prairies near Houston; on different Composite, 
such as Liatris, Solidago, Helianthus, Rudbeckia, and on Myrica 
cerifera; flowering in August; FE’. Lindheimer. 
Flowers rather large, but variable in size; segments of calyx 
always very acute, ovate or ovate-lanceolate, somewhat shorter 
or a little longer than the tube of the corolla. 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. 
C. neuropetala is distinguished from C. hispidula by, its per- 
fect 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
