SYSTEMATIC ARRANGEMENT OE THE SPECIES

IX. 453; not of Wight. Cassuta Arabica, DesM. Et. 72. - A well-marked species, the most common one in f473 C23H 
Egypt, and extending to the eastern shore of the Red Sea. It was collected in the former country by 
l , 354 ^ UChe r E1 °fl 1418 5 S - Kscher! KraUk! and ^ a11 * Lippi! — in Hb. Vaillant, where it is 
abe lled as Cuscuta sulphurei colons ^gyptiaca, flore niveo,” etc., - Arabia, on the Sinai, Rueppell! Schimper! 
nro. 140. I cannot see how it,is possible to ascribe to it capitate stigmata; nor is the capsule exactly baccate This 
last error, however^ is easily accounted for, as only the fully ripe capsule will separate from the base, and with quite a 
small opening. The Sinai plant-the original C. Arabica- has shorter pedicels, denser glomerules, cordate-sagittate 
an ers, an arger, even incurved, scales. Var. JEgyptiaca is distinguished by its longer pedicels, looser umbel, rather 
orbicular anthers, and smaller, often bifid scales, which sometimes seem to be reduced to mere teeth. It may possibly 
be the luxuriant torm, corresponding to G. Trifolii , and growing on cultivated plants. 
Sect. 3. CLISTOCOCCA. 
. Th * s represented by a single Asiatic species, is closely allied to Epistigma , but distinguished from it and 
all its other allies by the really baccate capsule, which at maturity separates from the persistent calyx, entirely covered 
by the closely enveloping corolla. The styles are subulate, much thicker at base, usually longer than the thin and 
pointed stigina. Flowers sessile, densely clustered. 
15. C. capitata, Roxb. FI. Ind. I. 448. C. rosea , Jacquemont! in Hb. — Roxburgh’s description, as far as it 
goes, agrees well enough with the species I take for it, which is, so far as I. know, the only papillate Cuscuta in India; 
but it seems to be far from common there. It is, on the contrary, confined to the mountain districts, and to an eleva¬ 
tion of from 6,000 to 12,000 feet. — The lanceolate lobes of the deeply slit calyx and corolla are covered with hemi¬ 
spherical or subcylindric papillae, consisting of numerous very minute cells ; scales in the lower part of the tube, not 
reaching to the middle, rounded or bilobed, dentate ; styles as long as ovary, much shorter than capsule ; capsule very 
thin and fragile, but strengthened by the dry corolla forming a tough coating over it; intrastylar aperture large.— 
Flowers over 1J lines long, often rose-colored ; seed oval, 0.6 lines long.

1550; on Thymus , 7,000 to 10,000 feet high, Thomson! in Kumaun, 12,000 feet high, Strachney and 
Wmterbottom! nro. 3, in part (in some herbaria the Indian form of C. Europcea is preserved under this [474 (24)] 
Sect. 4. PACHYSTIGMA. 
Stigmata cylindric or oblong, obtuse, thicker than the filiform styles. Capsules bursting transversely, late, and 
not by a proper joint. Seeds compressed, indistinctly triangular, obliquely truncate at base, with a very short 
perpendicular or slightly oblique hilum. 
Flowers pedicelled, disposed in a loose fascicled inflorescence; pedicels usually supported by bracts, only the 
latest ones naked. Corolla remaining on the top, or, in G. Africana , at the base of the capsule. 
The three species of this group inhabit southern Africa, and are usually parasitic on evergreen shrubs. The form 
of the stigma is intermediate between that of Eucuscuta and of Grammica, and the inflorescence is similar to that of 
the latter.

Cape of Good Hope, Dutuitskloof, 3,000 feet high, on Staavia, Drege! Mund and Maire! Harvey! in Hb. 
Hooker; Roxburgh! in Hb. Lambert, now Delessert. — The broad and short flowers, with broadly oval and obtuse 
lobes, and the 5-angled, or rather winged calyx, distinguish this species at first sight from both its allies. Choisy has 
confounded it with his C. Africana , as not only his reference to Drege’s specimen but also his own label to this same 
specimen in De Candolle’s authentic herbarium prove. — Flowers about lf-lj lines long, If wide when fully 
expanded; styles usually longer than stigmata, only in very young flowers of the same length. Fruit and seed 
V 17. C. nitida, E. Meyer! in sched.; Choisy! Cusc. 177, t. 2, f. 1, and DC. Prod. IX. 454. —Well distinguished 
by the broad and acute lobes of the calyx, the narrowly lanceolate acute lacinise, and the stigmata, which 
usually are much longer than the styles, rarely of the same length; stamens half as long as lacinise; [475 (25)] 
incurved scales as long as, or sometimes longer, than tube ; capsule irregularly circumscissile.
