194 ENUMERATIO ACANTHACEARUM 



a better one, as has been sufficiently proved by its adoption, with 

 a few additions and corrections, by Mr. Bentham in ' Genera 

 Plantarum,' a work which must remain the chief guide to the 

 classification of the genera, until some character more philosophi- 

 cally and phylogenetically valid than the estivation of the corolla 

 shall have been applied to the Order. 



I purpose commencing with an enumeration of all the species 

 collected by Dr. Welwitsch contained in the British Museum. A 

 considerable number of these are also at Kew ; but the specimens 

 are, as one would suppose, not in so good a condition, although 

 in most instances they are fairly serviceable ones. After this I 

 shall deal with a few geographical details.
