Tylophora. | ASCLEPIADE& (Brown). 765 
column arising from the base of the corolla; anthers erect, tipped 
with a small membranous appendage, which is sometimes reduced to 
a mere hyaline margin, their fertile part not rising above the margin 
of the style-apex, usually opening by crescent-shaped transverse 
slits. Pollen-masses very minute, suberect, horizontal or pendulous, 
attached in pairs to the minute pollen-carriers by very slender 
caudicles affixed at their middle or near or at one end. Style-apex 
rarely slightly exceeding the anthers, pentagonal or 5-lobed, de- 
pressed, flattened and often with a small central boss, or convex. 
Follicles usually narrowly lanceolate or lanceolate-fusiform, smooth, 
sometimes winged. Seeds crowned with a tuft of hairs. 
Twining or rarely erect perennials ; leaves opposite, petiolate ; inflorescence 
lateral at the nodes or axillary, sometimes consisting of a single pedunculate or 
sessile umbel-like cyme or flower-cluster, sometimes of 2 to several flower-clusters 
scattered along a single-jointed axis or along the branches of a dichotomously 
branched cyme or panicle. 
Distris, Species many, widely distributed in the tropical and subtropical 
regions of the Old World. 
This genus is usually easy to recognise by the peculiar character of its 
inflorescence and the corona-lobes usually reduced to mere tubercles. Since the 
publication of the Tropical African Asclepiads I have examined some species in 
which the pollen-masses are distinctly pendulous; as is also stated by 
Dr. Schlechter, and I now doubt if any of them have really erect pollen-masses ; in 
some they appear to be ascending, in others neither erect nor pendulous, in others 
still, they are distinctly pendulous, so that the genus is distinctly intermediate in 
character between the Cynanchee and Marsdeniex, and I now think that 
Tylophoropsis must be reduced to T'ylophora. The pollen-masses are always very 
minute, and their position in the anther-cell is sometimes very difficult to 
determine. The caudicles are usually very slender, and at times I have failed to 
find any trace of them,
