524 ASCLEPIADE® (Brown). 
+t Corona of 5 narrow grooved lobes upon the corolla-tube and adnate up 
to its mouth, incurved at the tips, ciliate on the adnate part; none on 
the staminal column. 
XXXII. Gymnema.—Twining shrubs. Umbels often 2 from the same node and 
opposite, sublateral. Flowers small. 
+++++ Corona none. 
XXXIV. Rhyssolobium.—A much-branched shrublet, with rigid woody whitish- 
puberulous branchlets. Leaves small and thick. Flowers very small, 1-3 
together, subsessile at the nodes. 
Tribe V. Crropecie®.—Anthers erect, connivent, or incumbent on the top 
of the style, with or without an apiculus or terminal appendage, sometimes tipper 
with hairs. Pollen-masses erect, ascending or horizontal in the-anther-cells, 
pellucid along the inner margin or at the apex (see also Hmplectanthus). Pollen- 
carriers sometimes with a wing-like expansion on each side. Stems herbaceous 
or fleshy, erect, prostrate or twining, with well-developed leaves, rarely leafless 
and then without distinct angles. 
* Corona-lobes all in 1 serics on the staminal column opposite (or on or 
below the back of) the anthers, none alternating with them. tose 
+ Corona of 5 lobes, without a dorsal arm or an appendage on their inner 
face, 
XXXV. Orthanthera.—Corolla-tube elongated, not bearded at the mouth, more 
or less inflated at the base. Corona-lobes A-shaped, adnate to the staminal 
column, with free reflexed wing-like margins. Stems prostrate with broad 
Jeaves, or erect and shrubby with narrow leaves. 
XXXVI. Sisyranthus.—Corolla-tube short, campanulate or globose-campanulate, 
sometimes bearded at the mouth and on the lobes. Corona-lobes erect, partly 
adnate to the staminal column, ovate or oblong and entire, or broadly- 
cuneate or subrhomboid and 3-toothed, with the middle tooth sometimes 
bifid. Roots thick, fleshy, clustered. Stems erect, rather slender, simple or 
branched. Leaves long, linear. Flowers small, in pedunculate umbel-like 
clusters. 
XXXVIII. Macropetalum.—Corolla-tube exceedingly short; lobes very long, 
reflexed straight back. Corona-lobes exserted, adnate to the staminal culumn 
at the base, free and linear-lanceolate above. Rootstock a tuber. Stem erect, 
slender. Leaves filiform, 
++ Corona of 5 broad bifid lobes with a long linear filiform appendage on 
their inner face, or the dorsal part of the lobe short and subulate, 
appearing to arise from the back of the long linear-spathulate inner 
part. 
XLII, Anisotoma.—Corolla-tube short, not bearded. Herb branching at the 
base into many prostrate stems. Leaves cordate. Flowers small in sessile or 
pedunculate umbel-like clusters. (See also Brachystelma.) 
** Corona-lobes in 2 or 8 series, or falsely in 1 series of 3-fid lobes, all on 
_ the staminal column ; I series or its teeth alternating with the anthers, 
the other 1 or 2 series opposite to them. Inner corona-lobes shorter 
than, equalling or longer than the anthers. 
+ Corolla-tube tubular, 2 to several times as long as its diameter at the 
middle, often inflated at the base ; lobes free or united. : 
XXXIX. Riocreuxia,—Outer corona sometimes 1-seriate, of 5 subulate simple or 
bifid lobes radiating horizontally or of 5 minute ascending or spreading often 
pouch-like bifid lobes ; sometimes 2-seriate, with 5 minute bifid or emarginate 
lobes alternating with and just beneath the radiating subulate lobes, forming 
an irregularly 15~20-toothed frill. Inflorescence a branching cyme or panicle 
with few or many clusters of flowers scattered along its branches, or the 
clusters racemosely arranged along a single peduncle or sessile at the nodes.
