the rather narrow pollen-carriers in pairs by short caudicles. Style 
with the terminal part always produced beyond the pollen-carriers, 
capitate, hemispherical, subconical, obtuse or truncate, usually furrowed 
below. Follicles (only seen in one species) fusiform, beaked and taper- 
ing at the base into a stipe, smooth. Seeds-crowned by a tuft of hairs. 
—Perennial herbs with a tuberous rootstock and milky juice. Stems 
usually simple and probably solitary, rarely branched. Leaves opposite. 
Umbels pedunculate, terminal and lateral between the bases of the 
upper leaves, mostly arranged in a terminal corymb. 
Species 5 or 6, endemic. 
Closely allied to Asclepias, differing chiefly in the petaloid coronal-lobes, which 
are larger and more conspicuous than the often revolute petals; the anther- 
appendages, too, are erect and the apical part of the style more elongated, rising 
above the pollen-carriers. 
In the diied state, owing to pressure, the coronal-lobes sometimes have their 
claw part so much flattened that its complicate nature disappears, and it then 
appears to be flat with two or three teeth standing upon it. 
Coronal-lobes with 3 teeth on the claw. 
Corolla-lobes revolute; blade of the coronal-lobes 
elliptic, elliptic-oblong, toothed on the margin . 1. M. rosea. 
Corolla-lobes not revolute; blade of the coronal- 
lobes narrowly oblong, entire or irregularly lobed 
or toothed at the apex. 3 5 : 2. M. Whyte.

1. M. rosea, Oliver in Trans. Linn. Soc. xxix. 111, t. 76. Tuber 
carrot-shaped, milky, Stems 12-20 in. high, simple or slightly branched, 
pubescent, principally along two lines. Leaves spreading ; petiole 1-1} 
lin. long; blade 14—4 in. Jong, 4-8 lin. broad, narrowly oblong, acute, 
cordate, subcordate or rounded at the base, both sides with a minute 
Sparse pubescence. Umbels about 3, corymbose at the apex of the 
stem, few-flowered ; peduncles 3-4 lin. long, subtomentose ; bracts 1-1} 
lin. long, subulate, subtomentose ; pedicels 14~3 lin. long, subtomentose. 
Sepals 14-13 lin. long, lanceolate, acute, subtomentose. Corolla-lobes 
ascending, with revolute tips, 24-23 lin. long, ? lin. broad, linear-oblong, 
obtuse, pubescent on the back. Coronal-lobes arising at the base of the 
staminal-column, petaloid, 3-34 lin. long, 2-2} lin. broad, complicate in 
the basal half, with the inflexed margins produced into erect linear acute 
teeth, with a similar tooth between them on the face of the claw; upper 
half expanded into a broad flat spreading obovate-oblong or subelliptic 
blade, toothed all round. Anther-appendages ovate, acute, erect, con- 
nivent, twice as long as the apical part of the style which is rather 
short, subcapitate and furrowed.—K. Schum, in Engl. Pfl. Ost-Afr. C.
