able the Earl of Derby. It was collected in Macalisberg, 

 by Mr. Burke (now employed on a similar mission in 

 North-west America, and in California), while engaged in 

 procuring animals and plants for that distinguished noble- 

 man, in the interior of Southern Africa. It flowered in 

 the stove at Knowsley, in May, 1844, and rarely has a 

 more desirable plant been introduced to our collections. 

 The tuberous root is large, solitary, quite globose ; the 

 upper part elevated above the earth, and producing 

 from its summit a stem, which soon divides into several 

 erect, rather stout, succulent branches, bearing opposite 

 leaves, and large, handsome, red-purple flowers in the axils 

 of those leaves. The mouth of the flower has a circle of 

 short, downy hairs. The fruit is drawn from dried speci- 

 mens, brought home by Mr. Burke.
