Stomatostemma. | LXXXV. ASCLEPIADEX (BROWN). 
Species 1, also in South Africa. 
I have generically separated this plant from Cryptolepis, chiefly on account ot 
the position of the coronal-lobes. These are much more distant from the stamens 
than they are in Cryptolepis, occupying the same place that the sinus-pockets do in 
that genus and probably represent the same organs, whilst the coronal-lobes of 
Cryptolepis (arising at the middle of the corolla-tube), are not represented in Stoma- 
tostemma. The corolla also differs from that of Cryptolepis in being more inflated 
and more obtuse when in bud, and in having a much broader tube and broader lobes 
than in any species of that genus, The generic name is formed from oropa, a 
wouth, and oreupa, a crown, in allusion to the position of the corona at the mouth 
of the corolla-tube, 
1. S. Monteiroz, V. ZH. Br. A small bush 4-5 ft. high, or a 
climber, glabrous in all parts. Leaves 14~3 in. long, rae in, broad, 
oblong, lanceolate or cuneate-obovate, obtuse or acute, sometimes apicu- 
late, narrowed at the base into a 1—2 lin. long petiole. Cymes 1-1} in. 
long, few-flowered, terminal and subcorymbose, or arranged along the 
terminal part of the stem and branches in a racemose manner ; pedicels 
3-4) lin. long, with two minute bracts at about the middle. Sepals 
1-1} lin. long, ovate-oblong, obtuse. Corolla about 1 in, in diam., 
¢ream-coloured with a purple-brown centre, somewhat inflated ellipsoid 
and obtuse when in bud ; tube 2-3 lin. long, broadly campanulate ; lobes 
2 in. long, 2-21 lin, broad, oblong, obtuse, with revolute margins. 
Coronal-lobes inserted at the sinuses of the corolla, 1 lin. long; clavate, 
fleshy, dark purple-brown or blackish in the dried state. Anthers 
acuminate, connivent over the short conical apex of the style, whitish

Also at Delagoa Bay and in the Transvaal. 
This species is stated by Mr. McCabe, on his label, to be a “small bush or tree 
growing among rocks,” whilst Mrs. Monteiro, who collected it at Delagoa Bay, and 
Mr. Galpin who collected it near Barberton iu the Transvaal, both state that it is a 
climber. But I cannot find the least difference in the flowers from the different 
localities. It would appear that in the more humid coast region the plant is a 
climber with broader leaves and a somewhat lax inflorescence, whilst in the drier 
inland region it becomes a bush with narrower leaves and a more compact In- 
florescence,

_ , Calyx D-partite. Corolla rotate or rotate-campanulate, very deeply 
)-lobed ; lobes broad, overlapping to the left in bud. Corona in- 
distinct, arising from the bottom of the corolla, annular, with 5 very 
short lobules, which are adnate to the base of the filaments of the 
stamens. Stamens 5 ; filaments free ; anthers erect, oblong, appendaged 
at the apex, connivent over the apex of the style, united to the dilated 
part of it at their base, and cohering by their appendages at the a
