88 SYSTEMATIC ARRANGEMENT OF THE SPECIES 
broadly ovate-cordate anthers ; scales reduced to very thin and small ovate membranes, with 4-7 or 8 ir- [485 (35)] 
regular teeth inserted below the middle of the tube, perhaps sometimes entirely wanting; ovary slightly 
conic, with styles scarcely reaching to the throat, just exsert in fruit. In the figure in the Flora Peruviana the 
cylindric corolla and the circumscissile capsule are correctly given. — Peru, on shrubs, and on Medicago sativa, Ruiz 
& Pavon! not found since. 
It is well known that Choisy, 1 ¢., and every author after him, myself included, took the Cuscuta — which 
twenty years ago made its appearance in different parts of Europe, in fields of Medicago, said to have been imported 
from Chili —for this species. The figure, as well as the original specimens, prove this to have been a mistake ; that 
plant is C. racemosa, Mart., as will be shown below. Whether the scales are ever really absent, or only very small and 
difficult to find, I cannot say. In eight or ten flowers which I carefully examined I could not always discover them, 
especially after soaking the flowers; unfortunately, the specimens are injured by too hard pressing. With the excep- 
tion of the smaller flowers and indistinct scales, I find nothing to separate this from the other forms, which are more 
abundant and better developed, but had to yield their specific names to priority. 
31. C. prisMATIcA, Pavon! mss.; Choisy! Cusc. 182, t. 3, f. 2; DC. Prod. IX. 457, — A very distinct species, 
and one of the few without any svales. Choisy’s figure as well as description is not very correct. Bracts lanceolate 
acuminate; flowers subsessile, 3 lines long; calyx a obconic, fleshy, deep red, 5-angled from the decurrent 
earinz of the unequal, i acute or cuspidate imbricate lobes; corolla leet cylindric, long exsert, externally 
granulated, laciniz 4-6 times shorter than the tube, olen, obtuse, somewhat involute at the margins, crenulate ; 
anthers ovate-cordate, sia ; ovary turbinate ; capillary styles shorter than the tube, much longer than the ovary. 
I have seen no fruit of this plant, but venture to class it here on account of its close affinity with the last species, from 
which, however, it is abundantly distinguished by all the characters one a The only specimens seen are 
from Guayaquil, Pavon! in Hb. Boissier, and Henke! in Hb. Mus. m. 
§ 3. Leptolobe. 
Styles slender, usually capillary ; flowers rather small, membranaceous ; lobes of calyx and corolla acute, often 
acuminate, commonly narrow and elongated, as long or longer than the usually campanulate tube; scales absent 
only in the last species; capsule surrounded or covered by the corolla, opening by irregular or rather regular 
circumscission.

Near a deserted Rancho, on a rocky hill-side in peor parasitic on Amarantus; fl. Sept., Chs. Wright! 1624 
(529). — “ Whole plant very white.” Clusters of the large and showy flowers at last crowded, more than 1 inch in 
diameter ; flowers 2} lines long, on pedicels as long or shorter than the calyx, which in one specimen covers the 
tube, and in another is shorter; scales large, irregularly toothed towards the apex only; capsule globose ; readily 
opening towards the base by a sal! circular aperture ; stylar portion of dissepiment scarcely half as long as capsule ; 
seeds usually all four developed ; oval, about } line long, verrucose, with a small linear vertical or transverse hilum. — 
t, as well as in some particulars, this species very closely approaches to C. corymbosa, but seems to be 
well distinguished by the characters given, especially the deeply divided corolla, its Seite laciniz, the broad dentate 
scales, the small basal opening of the capsule, the seed, etc. It is not impossible, however, that intermediate forms 
may yet be discovered, which will oblige a fabio monographer to unite them. On the other hand, the similarity to 
C. subinclusa — a Californian species, which has decidedly baccate capsules — is so great that one might be induced to 
doubt the diagnostic importance of this character.

The specimen consists of an intricate mass of deep yellow stems, with few heads of flowers just develop [487 (37)]

seems to be nearly allied to C. wmbellata, but is distinguished by more compact heads, larger — broad and
