 Vatkp, I. c, separates this into two species. 



23. V. mlsera, 0. Sf H. Annual, decumbent, pilose-pubescent 

 herb. Stem-leaves linear-oblong to oblong-oblanceolate, scarcely 1 ft.

 or hispid-pilose beneath, l-l-J in. long. Capitula ^ to nearly J in. in 

 expansion, subhemispherical, shortly pedicelled or subsessile, in few- 

 flowered interrupted cymes on terminal peduncles of 1-3 in., forming 

 a diffuse somewhat paniculate inflorescence ; bracts linear-lanceolate 

 acute greenish above, apex often spreading or subrecurved. Anther-
