I believe the two are 



varieties of the same species ; indeed, my cultivated specimens serve to connect 

 them. I noticed at the time that Drummond's plant, on which Centauridium was 



3 character of Xanthisma : but 



founded, agreed in many respects with De Candolle's 

 in that the involucral scales were said to be very obtuse

slendcr, are flat, and entirely Asteroid in character. De Candolle's prlor name should 



rcplace ours, but the genus must occupy the position I had assigned to it. 



I have 



elsewhere remarked that the cauline leaves are often toothed, and that the radical 

 ones are laciniate-pinnatifid, or even bipinnatifid.
