To the crowd of species of this most difficult genus a 

 new one is added with some hesitation ; and, till the specific 

 marks of the genus are better understood, it will be im- 

 possible to feel quite sure that varieties are not introduced 

 under the name of species. 



I must confess, however, that 1 can find no recorded 

 plant to which the present can be referred, as a probable 

 variety. It approaches nearest to X. elegans of this work, 

 fol. 1581, and to L. leptocarpus of Mr. Bentham, but it 

 seems to differ from both those plants in the somewhat re- 

 markable character of the flower-buds being separated from 

 each other by a considerable distance even when quite young. 

 From L. Hartwegii, which is L. bilineatus of Mr. Bentham's 

 " Plantse Hartwegianse," and which is I fear too near X. 

 mexicanus, the short deciduous bracts and freedom from 

 villosity sufficiently separate this plant. 



It was obtained from Mexico by George Barker, Esq. of 

 Birmingham, and is worthy of bearing his name, for it is a 

 very handsome species. 



It may be treated either as a half-hardy annual, or as a
