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 ba.^e 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 cliiefly 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 disajjpears, 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 . \. M. rosea.

 lubes narrowly oblong, entire or irregularly lobed

 obtuse, pubescent on the back. Coronal-lobes arising at the base of the 

 staminal -column, petaloid, 3-3J lin. long, 2-2J lin. broad, complicite in 

 the basal half, with the inflexed margins produced into erect linear acute

 half expanded into a broad flat spreading obovate-oblong or subelliptic 

 blade, toothed all round. Anther- appendages ovate, acute, erect, con-
