PLANTJE WRIGHTIAN^. 



Y. 



Texas ; Sept. Also gathered by M. Trecul in the same district. — " Plant growing 

 in dense tufts, much branched from the base," a span to a foot high. Leaves crowd- 

 ed, 8 to 12 lines long, linear or filiform, fleshy, apparently terete, very obtuse. Pe- 

 duncle naked, three to five inches long. Head four lines in diameter, subglobose- 

 ovoid, larger and rounder than in V. Mexicana, the short involucre less tubinate. 

 Heceptacle, paleoe, flowcrs, &c. nearly the same ; but I find no traces of a pappus. 

 The capitula have considerable resemblance to those of Salmea, the only genus with 

 which I can compare this and the plant to which I gave the name of Varilla Mexi- 

 cana, PL FendLp. 106, adnot But the style is not asteroid in cliaracter, the aclienia 

 are not obcompressed nor two-awned, &c. The present plant is truly a congener of 

 V. Mexicana, although destitute of a pappus.

 the same species as a small unnamed specimen from California, Douglas, in the

I may herc correct a transposition in the characters of Angianthus and Phyllocalymma, as printed in 

 ».. Conspectus of the Genera of the AngianthcEO, contrlbuted to Hooker's Journal of Botany and Kew 

 Garden Miscellany, for April, 1851. It is Angianthus, and not Phyllocalymma, which Ims the bristles of 

 Ihe pappus subplumose. This cliaracter should read thus :
