OF THE GENUS CUSCUTA. 83 
This is C. Africana, a. Drege! C. Africana, Ecklon & Zeyher! 20, 77,11, and 21,1,11. C. Burmanni, Choisy! 
Cuse. 177, and DC. Prod. IX. 454, is the same plant, as I have satisfied myself by a careful examination of the original 
specimen in Hb. Delessert. This specimen is further interesting as it bears the inscription “ C. Americana,” it would 
seem, in Thunberg’s handwriting. This may therefore be the original plant, which Thunberg first took for Linnzus’ 
C. Americana, and afterwards named C. Africana, so that C. nitida would be the true Thunbergian Africana; but 
even if this be so, it will be better to leave the nomenclature as at present established, especially as quite probably 
Thunberg confounded both species. Another fact bearing on this question is, that in Jussieu’s Herb., now in the 
Museum of the Jardin des Plantes, a specimen of C. Chinensis is preserved, labelled ‘* C. Americana, Thunb. C. B. Sp. 
Thunberg ded.” So it seems that at one time Thunberg himself took C. Chinensis for his Americana; but as, so far as 
known, this plant does not occur at the Cape, it is quite possible that he brought this specimen from India or China, 
and confounded all those plants under one name. He does not mention C. Chinensis or any other Cuscuta from those 
regions. 
C. nitida seems to be one of the commonest species at the Cape of Good Hope, and has been collected there by 
almost every botanist. Dr. R. C. Alexander communicated a specimen with firmer red stems ; some of Drege’s 
specimens exhibit a granulated, somewhat scabrous, calyx. 
18. C. Arricana, Thunberg? FI. Cap. 568 and Phyt. Bl. 17 ; Choisy! Cuse. 176 and DC. Prod. IX. 454 pro 
parte. —I have above stated my doubts about the identity of Thunberg’s plant, and my reasons, nevertheless, for 
retaining his name for this species. The older botanists also seem to acknowledge this for C. Africana, as I find a 
specimen thus labelled in Willdenow’s Herb. nro. 3161. Choisy’s description entirely refers to this plant, though one 
of the specimens he cites belongs to C. angulata. 
is well characterized by the very loose inflorescence, the long pedicels, the capillary styles, which are much 
longer (often more than twice as long) than the oblong and thick divergent stigmata; calyx short, lobes broad, 
obtusish, verrucose, imbricate ; lacinie linear-oblong, obtusish, involute at the margin and at tip, erect or spreading ; 
scales large, often longer than the tube, incurved ; capsules, in the only specimen in which I could find 
any, almost baccate, or opening very late, with the corolla persistent at base, mostly with a single globose [476 (26)] 
seed, 0.7 lines long; flower 1-14 lines long. — C. Americana, Thunb. Prod. 32, not of Linnzus, is the 
same as his later C. Africana. —Our plant was collected by Drege! 7010, and labelled by him C. Africana, d; it is 
Ecklon and Zeyher’s! 22,70, 10. Schrebera schinoides, L. Sp. 1662, is—as the figure in Nov. Act. Ups. I. t. 5, f. 1, 
shows — this species parasitic on Myrica Africana. C. fusiformis, Willd. Rel. in R. and S. VI. 209, referred here by 
Choisy, a misprint for C. funiformis, as spelt in Willd. a? nro, 3156, is not a Cuscuta, but a Cassyta from the Cape, 
as Schlechtendal has long since stated. 
C. Capensis, Choisy! Cusc. 175, t. 1, f. 4, and DC. Prod. IX. 454, is a large form of this species; flowers 2}-22 
ries ees ; calyx smoother and shorter ; lacinie longer, somewhat acutish; scales smaller. It bears the same relation 
Africana that C. Trifolit does to C. Epithymum. — Drege! 7833, Dr. Thom! Dr. Alexander! 
Sect. 5. EUGRAMMICA. 
Styles of unequal length, subulate or cylindric ; stigmata capitate ; capsule bursting transversely more or less 
regularly, in C. Jalapensis iegolarly circumscissile ; seeds often only one or two in each capsule, rounded or flattened, 
truncate at base, or hooked; hilum forming a transverse or oblique, rarely a perpendicular line, often very short, or 
reduced to a point. 
The inflorescence is quite variable, Soci few-flowered loose cymes, or compound racemose or umbelliform 
cymes with pedicelled flowers, or compact clusters with subsessile flowers, with bracts at the base of each, or at least 
the primary pedicels or flowers. The corolla remains at the base or on the top of the capsule, or completely 
envelops it, 
Most species of this section inhabit South America, the West Indies, and Mexico. One (C. umbellata) extends 
into the southwestern parts of the United States, and two (C. odontolepis and C. a are peculiar to that region; 
two others are natives of Asia, one extending to New Holland, the other to eastern Africa 
§1. Subulate. 
Styles thick and short, subulate from a broad base ; flowers mostly large and of a firm texture ; scales wanting in 
one (the first) species; corolla enveloping the whole or the greater part of the ripe capsule in all but the first ; capsule 
opening readily by more or less regular circumscission. 
* Lobes of calyx orbicular, imbricate. [477 (27)] 
GRANDIFLORA, HBK.! N. Gen. Sp. III. 123, t. 213; DC. Prod. IX. 457; not Wallich Cat. — This 
ets and striking species is so well described by Kunth that it is not necessary to add a single line. He 
already mentions (as he also does in regard to C. Popayanensis) the circumscissile opening of the capsule, ignored
