ASCLEPIADEZE (Brown). 521 
Tribe II. SkEcaMonex.—Anthers erect or ascending, with more or less 
fimbriated appendages. Style-apex often exserted beyond the anthers. 
VII. Secamone.—Climbing shrubs. Flowers small, in cymes. Corona of 5 
simple lobes more or less adnate to the staminal column. 
** Pollen-masses solitary in each anther-cell, attached in pairs to each of the 
pollen-carriers or to lateral expansions of them by long or short caudicles, 
or sessile in Fockea. Pollen-carriers hard, horny, sometimes pale, but 
usually black, brown ov dark-coloured. 
Tribe ILI. CynANcHE&.—Anthers erect, connivent-erect or rarely divergent- 
erect, tipped with entire or rarely toothed or fringed membranous appendages, 
which are often inflexed over the style-apex or upon its rim. Pollen-masses 
pendulous in the anther-cells, opaque, except in some species of Schizoglossum 
which have a small pellucid area just beneath the apex, and in Cordylogyne and 
Periglossum which are subtransparent at one end. 
+ Corona none or of 5 inconspicuous tubercles or scales on the corolla-tube 
alternating with tufts of hairs near its base, middle or top, none on the 
staminal column, 
VILI. Astephanus.—Corolla-lobes erect or spreading, not partly closing the 
mouth of the tube and without a hump on the back. Corona none, Slender 
. twiners. 
1X. Microloma.—(orolla-lobes connivent over or spirally arranged around and 
partly closing the mouth of the tube, often with a hump on the back. 
Corona-tu'ercles often present. Slender twiners or much branched and often 
rigid shrublets, 
t+} Corona of 5 broad simple lobes seated at the sinuses of and adnate to the 
corolla-tube, none on the staminal column. 
X. Parapodium.—Corolla-tube shortly hemispherical or globose-campanulate ; 
lobes recurved or spreading at the tips. Dwarf erect tuberous-rooted herbs, 
Stem simple. Flowers of moderate size, in lateral umbels. 
Tit Corona distinct, arising from the staminal column or in the angle 
between it and the corolla or both, none on the corolla. 
t Stems erect, decumbent or prostrate, never twining, herbaceous (rarely 
woody in Cynanchum). Rootstock often a tuber. 
$ Corona of 5 distinct free lobes in one series, often with one or more 
appendages or keels on their inner face; outer corona none or reduced 
to very minute lobules, teeth or (in Periglosswm) filiform processes 
_ alternating with the lobes. 
XL. Woodia.—Corona-lobes not exceeding the incurved-ascending, suberect or 
‘spreading corolla-lobes, dorsally flattened, not very fleshy in dried flowers, 
deeply trifid or quadrate with square shoulders and an incurved mid-lobe, 
with the margins incurved at the base and ascending the column as narrow 
wings, 
XII. Xysmalobium.—Corona-lobes shorter than the erect, spreading or reflexed 
corolla-lobes, very fleshy, often nearly or quite as thick as broad, or if dorsally 
flattened, then comparatively thick, solid, without a fissure or cavity on the 
inner side, veriously shaped, keelless or with 1 median keel, very rarely with 
2 keels or a tooth (but no other process) on the inner face, not acutely keeled 
down the back. (See also Schizoglossum periglossvides). 
XIII. Periglossum.—Corona-lobes shorter than the suberect corolla-lobes, 
dorsally flattened, spathulate; blade oblong, subcordate-oblong or ovate. 
sagittate, with 2 keels capped by a transverse ridge or tubercle (rarely without 
keels) on the inner face. Staminal column subglobose or globose-obovoid, 
constricted under the anther-wppendages. Pollen-masses subtranslucent at 
the free end and much shorter than their caudicles. Style not exserted beyond 
the anther-appendages.
