234 LXXXV. ASCLEPIADEZ (BROWN). 
Corolla always with a distinct campanulate or cylin- 
dric tube, but the flowers are sometimes very 
small and the tube short. 
Coronal-lobes arising from the corolla-tube clearly 
above the insertion of the stamens below 
the middle or at the base of the corolla- 
tube. 
Coronal-lobes arising at or a little above the 
middle of the corolla-tube ; erect or twining 
shrubs. (See also Tacazzea rosmarintfolia.) 2, CRYPTOLEPIS. 
Coronal-lobes arising in the sinuses at the mouth 
of the corolla-tube ; erect or twining shrub 3. STOMATOSTEMMA. 
Coronal-lobes arising at the insertion of the 
stamens above the middle or at the top of the 
corolla-tube ; herbs with a tuberous rootstock, 
dwarf, rarely twining . : - : . 10. RAPHIONACME. 
Corolla lobed nearly to the base; tube reduced to a 
mere ring; coronal-lobes arising from the 
corolla at the insertion of the stamens and often 
adnate to them at the base ; stems long, twining 
or straight, usually woody. (See also Raphio- 
nacme linearis, and R. splendens, which have 
a very reduced corolla-tube, but are dwarf 
herbs.) 
Coronal-lobes short and very broad, with or with- 
out a dorsal process ; stipules distinct, toothed 
or frill-like . 3 : . : : . 5. CHLOROCODON. 
Coronal-lobes long, filiform, subulate, linear or 
linear-lanceolate, simple or divided above into 
2-3 filiform segments; stipules (except in 
Tacazzea floribunda) none, or represented by 
a mere line connecting the bases of the petioles. 
Anthers glabrous. c ee A . 9. TACAZZEA. 
Anthers more or less hairy : F ; . 7, PERIPLOCA. 
Corona double, radiating ; outer lobes obtusely trigonous ; 
inner lobes obovate-oblong, boat-shaped, obcordate 
at the apex - ; é 3 x . 6. OMPHALOGONTS. 
TRIBE IT. Seeamoneze.— Filaments of the stamens connate into a tube, and 
adnate at the top to the dilated part of the style. Anthers erect or a 
with more or less fimbriated appendages. Pollen-contents of each anther-cell 
consisting of two distinct but exceedingly minute wary masses, Or the two masses 
more or less combined into one, attached in fours or in pairs to each of the pollen- 
carriers ; when apparently in pairs the seemingly single pollen-mass 1s sometimes 
more or less separable into two. Pollen-carriers minute, subquadrate, rather soft, 
pale in colour. 
Coronal-lobes laterally flattened or subulate; pollen- 
masses distinctly 4 to each pollen-carrier . . 11. SECAMONE. 
Coronal-lobes dorsally flattened; pollen-masses appa- 
rently 2 to each pollen-carrier, but each mass 
sometimes separable into two : 3 : . 12. ToXocARPUS. 
TRIBE III. Cynancheze.—Stamens with the filament-part when present ef 
nate into a tube, sometimes very short and ring-like (filaments free ™ ear 
lobium barbigerum); anthers adnate to the dilated part of the style, ™
