DovustFuL SPECIES. 
V.? azstuans, Lam. Dict. iii, 262, DC. Prodr. v. 618 (Inula estu- 
ans, L. Spec. ed. 2, ii. 1236), known from Plum. ed. Burm. t. 41, f 2, 
is wholly doubtful and probably not of this genus. It has very numer- 
ous long narrow linear rays and a multiseriate involucre. . 
V. ARGENTEA, Bertol. Fl. Guat. 435, if (as described) with neutral 
ray-flowers and triangular upwardly. villous achenes, is probably an 
Encelia. 
V. arGenTEA, Gaud. in Freyc. Voy. Bot. 463, is a very imperfectly 
characterized plant of the Marian Islands. 
V. conyzorpEs, Trew, Pl. Rar. 8, t. 6 (1763), without locality, does 
not appear to have been recognized by any subsequent author. We have 
not had access to the work in which it is figured. 
V. pecurrens, Vell. Fl. Flum. viii. t. 114, represented with race- 
mose heads and a pappus of several capillary bristles, is surely not of this 
genus. 
V. Humpoxptu, Spreng. Syst. iii. 577. V. helianthoides, HBK. 
Nov. Gen. & Spec. iv. 204, not Michx. We have seen no material of 
this species and are unable to place it satisfactorily. It is supposed to 
come from Ecuador, and is probably related to V. elegans, but has leaves 
“glabrous above.’ The Mexican plants referred to this species by 
Klatt are doubtless distinct. ; 
V.? miciroxra, Poir. Dict. viii. 459, of San Domingo, with opposite 
short-petiolate coriaceous dentate leaves, is still doubtful. 
V. mnvotucrata, Rich. Tent. Fl. Abyss. i. 409, is of Abyssinia and 
of doubtful generic affinities. : 
V. Mameana, André, Rev. Hort. xiv. 16, f. 5 (1885), is a hortieul- 
tural species described from the stem and foliage alone. There 1s 1° 
satisfactory evidence that it is of this genus.
