746 ASCLEPIADEZ (Brown). [ Cynanchum. 
that the linear-terete lobes alternating with the corolla-lobes are 
folded inwards, solid at the apical half, with the margins in- 
curved and forming a channel on the lower half (convex-cucullate, 
ex Schlechter), then decurrent as infolded-contiguous keels on the 
upper part of the tube ; the lobes opposite the corolla-lobes with a 
broad deltoid base, narrowed into a short linear obtuse point, 
slightly convex on the inner face below, but without keels or other 
processes ; staminal column 2-3 lin. long, with the greenish anthers 
forming a short cone, having 5 small excavations beneath them ; 
anther-appendages suborbicular, erect, adpressed to the sides of the 
stout conical obtuse greenish style-apex, which is shortly exserted 
beyond them, but is shorter than the corona; follicles 14-2} in. 
long, lanceolate-fusiform, tapering into a long beak, smooth, minutely 
puberulous. Flanagania orangeana, Schlechter in Engl. Jahrb. xviii. 
Beibl. 45, 10, and Journ. Bot. 1896, 457.

I find no character to generically distinguish this plant from Cynanchum. 
Although having a wide range, it would appear to be a rare plant, as only four 
collectors seem to have met with it since its discovery by Burchell in 1812. 
4. ©. Zeyheri (Schlechter in Engl. Jahrb. xx. Beibl. 51, 3) ; root- 
stock woody, deeply descending, dividing at ground-level into 
several or many herbaceous branching stems 3-12 in. long, more 
or less procumbent or when short sometimes erect, slender, glabrous 
to puberulous ; leaves small, thick, probably slightly fleshy when 
alive ; petiole 1-44 lin. long, channelled and puberulous above ; 
blade 24-11 lin. long, 2-6 lin. broad, ovate, oblong-ovate or sub- 
orbicular, obtuse or acute, apiculate, glabrous ; umbels lateral at 
the nodes, pedunculate, 2-5-flowered; peduncles 1-4 lin. long, 
glabrous or with a few very minute hairs; bracts very minute ; 
pedicels 2-4 lin. long, glabrous; sepals about 3 lin. long, ovate, 
acute, glabrous; corolla-lobes spreading, or ascending-spreading, 
usually more or less twisted, or at least with revolute margins, 
14-1} lin. long, $ lin. broad, linear-oblong, subobtuse, glabrous on 
both sides, dark brown (Harvey) ; corona arising at the base of the 
staminal column, #—1 lin. long, tubular-campanulate or cup-shaped, 
shortly 5-toothed at the top, not subentire as originally described, 
without keels or other appendages within, white ; staminal column 
+1 lin. long, contracted below the anthers into a rather long stipe ; 
anther-appendages ovate, acute, connivent over and concealing the 
umbonate style-apex ; follicles solitary, 13-2} in. long and 5-7 lin. 
thick, lanceolate-fusiform, tapering into a beak, with a keel on each 
side of the opening suture, smooth, glabrous ; seeds 3-3} lin. long, 
2 lin. broad, ovate, nearly flat on one side, very slightly convex on 
the other, finely rugulose-tuberculate all over, light brown.
