Sisyranthus. | ASCLEPIADE (Brown). 793 
Eastern Recion: Natal; Shafton, Howick, Mrs. Hutton, 407! Greenwich 
Farm, Riet Vlei, Fry in Herb. Galpin, 2737 ! 
Asclepias cucullata, Schlechter, has also been distributed by Mrs, Hutton as 407. 
The Greenwich Farm plant has flowers that are larger in all their parts than the 
type, the points of the corona-lobes being very much longer, but in every other 
character the two are identical, and it is probably only a luxuriant specimen. 
Misled by its external resemblance to S. Randii, and without having dissected it, 
this specimen was unfortunately originally quoted by Moore under that species in 
Journ. Bot. 1903, 200, but the corolla and corona are quite different. 
9. S. imberbis (Harv. Thes. Cap. ii. 11, t. 116); stems usually 
14-2 (rarely up to 34) ft. high, 4-1 lin. thick at the base, usually 
simple, glabrous ; leaves ascending or spreading, 14-5 in. long, }-1 
lin. broad, linear, acute, apparently folded lengthwise, glabrous, 
minutely and sparsely ciliate and denticulate on the margins ; 
umbels 2-6 to a stem, racemose, pedunculate, 2~7-flowered ; 
peduncles 4-1 in. long, rarely longer, slender, glabrous ; bracts 
4-2 lin. long, subulate or lanceolate, acuminate, ciliate ; pedicels 
2-41 lin. long, glabrous; sepals 1-13 lin. long, }-3 lin. broad, 
ovate-lanceolate, convolute-acuminate at the apical half, glabrous, 
not ciliate ; corolla glabrous outside, not bearded at the mouth, but 
furnished with 5 tufts of deflexed hairs at the top of the tube just 
below the lobes inside, otherwise glabrous; tube }-1 lin. long, 
14-13 lin. in diam., broadly campanulate or cup-shaped, slightly 
contracted at the mouth, 5-concave inside; lobes 14-13 lin. long, 
~1 lin. broad, ascending-spreading, oblong or ovate-oblong, acute 
or subobtuse ; corona-lobes erect, not exceeding or shorter than the 
anthers, 4-2 lin. long, broadly ovate or deltoid-ovate, obtuse or 
acute, with slightly reflexed sides and rounded basal angles ; 
staminal column 3-1 lin. long; anthers oblong, obtuse or with an 
obtuse apiculus, not ciliate; follicles 23-34 in. long, 2 lin. thick, 
terete-fusiform, tapering into a long acute beak, smooth, glabrous.

10. S. macer (Schlechter in Journ. Bot. 1897, 291, as to E. 
Meyer’s plant only) ; exactly like S. imberbis in habit, stem, umbels, 
and measurements of corolla ; leaves 4—5 in. long, 3-1} lin. broad ; 
corolla entirely glabrous within and without ; corona-lobes erect, 
shorter than the stamens, } lin. long and as much in breadth, 
usually very broadly ovate and entire or somewhat angular at the 
sides or 3-toothed, with the side teeth very small and the middle
