AN ACCOUNT OF THE GKNUS ARGEMONE. 807 



Shire Highlands, Milanji, Dec, No. 8G71. 



This species is very nearly allied to the South African S. cari- 

 natmn Schltr., but has more the habit of S. venustum Schltr., 

 although the very difterent flowers of the latter are more than twice 

 as large as in the former. The chief differences between our plant 

 and S. carinatum, excepting the habit, are to be found in the corona- 

 scales and the pollinia. The corona-scales of S. carinatum are 

 shortly acuminate, with a single ligula on the inner side, which is 

 about as long as the acumen of the corona-scales, but covers nearly 

 the whole inner surface ; whereas in the present species we have an 

 elongate apiculus, and inside a small lanceolate ligula, which is 

 much shorter than the apiculate production of the scales; below 

 this inner ligula we have here two narrow parallel lamella) on the 

 middle of the inner side, a character Avhich is totally wanting in 

 8. carinatum. The pollinia are very different in both species.

A most distinct species, allied to S. fasciculare Schltr., but a 

 much stronger-growing plant. Mr. Elliot's specimen is much larger 

 than the type in the British Museum.
