Doubtful Species. 



v.? ^STUANS, Lam. Diet. iii. 262, DC. Prodr. v. 618 {Inula ccstic- 

 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, Bcrtol. Fl. Guat. 435, if (as described) with neutral 

 ray-flowers and triangular upwardly villous acheues, is probably au 

 Encelia. 



V. ARGENTEA, Gaud. in Freyc. Yoy. Bot. 463, is a very imperfectly 

 characterized plant of the Marian Islands. 



V. CONYZOIDES, Trew, PI. Ear. 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. DECURRENS, Veil. Fl. Flum. viii. t. 114, represented with race- 

 mose heads and a pappus of several capillary bristles, is surely not of this 

 genus. 



V. HuMBOLDTir, Spreng. Syst. iii. 577. V. heliantJi aides, HBK. 

 Nov. Gen. &, Spec. iv. 204, not Michx. AVe have seen no material of 

 this species and are unable to place it satisfactorily. It is supposed to 

 come from Ecuador, and is probabl}^ related to V. elegans, but has leaves 

 ''glabrous above." The Mexican plants referred to this species by 

 Khitt are doubtless distinct. 



v.? ILICIFOLIA, Poir. Diet. viii. 459, of San Domingo, with opjiosite 

 short-petiolate coriaceous dentate leaves, is still doubtful. 



V. INVOLUCRATA, Rich. Tent. Fl. Abyss, i. 409, is of Abyssinia and 

 of doubtful generic affinities. 



V. Mameana, Andre, Rev. Hort. xiv. 16, f. 5 (1885), is a horticul- 

 tural species described from the stem and foliage alone. There is no 

 satisfactory evidence that it is of this genus.
