On a 7iew Genus of Asclepiadece,

great barclness, and coarsely grained, of a dull, yellowish brown colour^ 

 resembling the rock of the Neelgherries, specimens of which Dr. 

 Benza presented to the Society ; the felspar is frequently red or flesh 

 coloured, and sometimes white, but generally of a dull colour ; gar- 

 nets, some large and finely crystallized, abound in some specimens. 

 Fragments of a decayed rock, of porphyritic appearance, are alsa 

 among the specimens; the felspar of which has decomposed into a 

 fine kind of kaolin, which is mottled with red, from the decay of what 

 seem to be garnets. Conglomerates, formed of silicious pebbles, com- 

 plete the list. A small map of the neighbourhood of Wodiaghur, 

 some outline sketches of the hills, and representations of the axes of 

 the Khonds, accompanied Dr. Maxwell's paper : of which we shall 

 probably make use on a future occasion, when we hope to have it in 

 our power to publish a Memoir on Goomsur by a scientific officer.—

The specimen here figured, from the shores of the Red Sea, was com- 

 municated, along with several others from the same interesting locality, 

 by J. Nimmo, Esq. of Bombay. Among the collection, though of small 

 extent, I observed some other plants which appear to be new, but these 

 I have not yet found leisure to examine with sufficient care to deter- 

 mine the point. Owing to my previous familiar acquaintance with the 

 members of this order, a very slight examination was enough to satisfy 

 me that it belonged to a genus new to myself, and a more minute one 

 leaves no doubt of its being distinct from any yet published, so far at 

 least as I have the means of reference. 



It is certainly difficult to determine the affinities of this genus. The 

 peculiar structure of the anthers, assuming that the view I have taken 

 of them is correct, that, namely, of each being composed of a half of 2 

 adjoining deeply divided anthers adhering from the base to near the 

 point, at once separates it from every other described genus: but sup- 

 posing that the anthers are really what they appear, that is, formed ia
