This is treacherously like and no doubt closely related to V.fonti- 

 nalis S. Moore. The more hairy foliage, the 6-rowed narrower 

 acuminate involucral leaves, the setose achenes (not markedly 5- 

 angled and witli papillae between the angles) and the more numerous 

 setae to the pajipus are the main differences. It is not easy to under- 

 stand how de \Vildeman & Muschler could confuse this with V. laj)- 

 lioides O. Hoft'm. as they have done {J. c. p. 1G2).

The massed heads (the foliage is entirely difPerent) give this some- 

 what the ai)i)earance of Muschleria anffolensis S. Moore, but with 

 this all resemblance ends. A very distinct species.
