21. C micro St egium, K. Schum. in Ann. Istit. Bot. Eoma, vii. 39. 

 A divaricately much branched shrub, sometimes climbing ; branches 

 slender, soon becoming woody, glabrous. Leaves shortly petiolate, sub- 

 coriaceous, glabrous; petiole 1^-2 lin. long; blade 7-9 J lin. long, 

 1-2^ lin. broad, ovate-lanceolate, acute or obtuse, cuneate or somewhat 

 rounded at the base, slightly marginate. Umbels pedunculate, 4-5- 

 flowered ; peduncle 4-5 lin. long, minutely pubescent ; pedicels 1 J~2 lin. 

 long, minutely pubescent. Sepals h lin. long, triangular, glabrous. 

 Corolla 1 lin. long, carmine. Coronal-lobes not more than J lin. long, 

 ligulate, acute. Follicles 2 in. long, nearly 2 lin. thick, narrow, 

 acuminate.

I liace not seen this plant, but from the description suspect it will prove to be a 

 species of Secanitone.

 PI. ii. 749. 



Ciilyx 5-partite. Corolla deeply 5-lobed; lobes stellately spreading, 

 narrow, overlapping to the left in bud, scarcely twisted. Corona 

 arising from the angle between the corolla and the base of the staminal- 

 column, cup-shaped, 5-lobed; lobes induplicate-cucuUate, opposite the 

 corolla-lobes. Staminal-column arising near the bottom of the corolla, 

 nearly as long as the corolla-lobes, clavate, the filament portion slender 

 and longer than the corona ; anthers oblong, tipped with a membranous 

 appendage, which is inflexed over the style-apex. Pollen-masses 

 pendulous, attached in pairs to the pollen-carriers by flexuous caudicles. 

 Style not produced beyond the anther-tips, slightly convex at the apex. 

 Follicles stout, ovoid-lanceolate, beaked, smooth. Seeds turgid, crowned 

 with a tuft of hairs. — An erect plant, with woody stems, opposite 

 leaves, and sublateral cymes of moderate sized flowers. 



Spt-cies 1, extending through Egypt into Arabia. It is very closely allied to 

 Cynanchum, and should, perhaps, be united with that genus ; the chief diif erence 

 being that the lobes of the corona are placed opjwsite to the corolla-lobes, and the 

 filatiieiit part of the staminal-column is long, slender and exserted from- the corona. 



1. S. Argel, Hayne, Arzneyh. Gewdclise, ix. t. 38. Stems her- 

 baceous, erect, 1^-2 ft. high, branching, very minutely downy, leafy. 

 Leaves longer than the internodes, ascending ; petiole 1-2 lin. long ; 

 blade 1-1 J in. long, J— | in. broad, thick and rigidly coriaceous when 

 dry, probably fleshy when alive, varying from lanceolate to oblong- 

 ovate, acute or subacute, cuneate at the base, minutely downy on both 

 sides ; midrib flat above, prominent beneath ; veins indistinct. Cymes 

 axillary, 1^—2 in. long (including the J-J in. long peduncles), 11^-2 in. 

 in diam., densely marfy-flowered, minutely downy ; bracts '2-6 lin. long, 

 J-J lin. broad, linear-lanceolate, acute ; pedicels 2-3 lin. long. Sepals 

 2 lin. long, J lin; broad, oblong, acute, minutely downy. Corolla-tube 

 1 lin. long; lobes 2J-3 lin. long, | lin. broad, narrowly oblong, obtuse,
