 Nee. HumboldL Prof. TV. Jameson^ 



The present species seems to be liable to considerable varia- 

 tion. The usual state of the plant, as found in several localities 

 by Professor Jameson, is to be stemless ; the scape bearing a 

 single head of flowers. That here represented differs from 

 Cavanilles* figure in its evident stem; a variety which was first 

 noticed by Humboldt, and was found by him on Antisana. In 

 all the varieties, the entire plant is harsh and rigid. The leaves 

 are marked with oblong oblique reticulations. The head of 

 flowers is of a dark, almost black colour, when dry; probably 

 blue when recent; while the involucre is very pale and glossy, 

 forming a beautiful ray around the little mass of flowers.
