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. c., and every author after him, myself included, took the Omenta — 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. mcemosa, 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. 
Y 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 scales. Choisy’s figure as well as description is not very correct. Bracts lanceolate 
acuminate; flowers subsessile, 3 lines long; calyx elongated, obconic, fleshy, deep red, 5-angled from the decurrent 
carinse of the unequal, ovate, acute or cuspidate imbricate lobes; corolla almost cylindric, long exsert, externally 
granulated, laciniae 4-6 times shorter than the tube, oblong, obtuse, somewhat involute at the margins, crenulate; 
anthers ovate-cordate, sessile ; 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 above enumerated. The only specimens seen are 
from Guayaquil, Pavon! in Hb. Boissier, and Hsenke! in Hb. Mus. Bohem. Pr. 
§ 3. Leptolobac. 
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. 
\\ 32. C. odontolepis, n. sp.: caulibus tenuiter filiformibus ; floribus breviter pedicellatis bracteatis [486 (36)] 
in glomerulos laxiores demum decompositos crassos confertis; calycis breviter campanulati profunde partiti 
nitidi lobis ovato-triangulatis acutiusculis tubum corollse profunde campanulatum subsequantibus; laciniis ovato- 
lanceolatis acutis demum patulis reflexisve tubo paulo brevioribus; antheris ovatis filamenta subulata brevia sequanti- 
bus; squamis late ovatis e tubi basi oriundis ad medium adnatis faucem fere attingentibus versus apicem grosse 
dentatis; stylis capillaceis ovario depresso-globoso multoties longioribus e fauce paulo exsertis demum elongatis ; 
capsula corollse rudimentis calyptrata rite circumscissa. 
Near a deserted Rancho, on a rocky hill-side in Arizona, parasitic on Amarantus ; fl. Sept., Chs. Wright! 1624 
(529). — “ Whole plant very white.” Clusters of the large and §howy flowers at last crowded, more than 1 inch in 
diameter; flowers 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 small 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._ 
In general aspect, 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 acute laciniae, 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 future 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.
