 lobi 2 mm. long. Styli rami 2 mm. long. Acha?nia 2 mm., pappi 

 squamae 1 mm., setae 7 mm. long. 



V. ])r(sm,orsa Muschler and V. cnsteUana S. Moore are close to 

 and at first fright greatly resemble this, which is a larger-headed plant 

 than either with relatively longer and narrower involucral leaves and 

 different achenes and pappus.

To be inserted close to V. Byitfeniana Hiern and Y. carcltolepis 

 O. Hoffm. ; the chief difference resides in the involucres.

Muschler and de Wildeman refer No. 2546 quite wrongly to 

 V. calvoana Hook. fil. {I. c. p. 159). All three numbers are attached 

 to specimens perfectly conspecific with the type, Kassner, 2845 a.
