1. Vicoa auriculata, Cass, in Ann. Sc. Nat. ser. 1, v. 17 (1829) 

 p. 418. A slender, erect, rigid, leafy herb 1-3 ft. high ; stems terete, 

 striate, glabrous or pubescent ; branches often numerous in the upper 

 part, ascending, terete, more or less pubescent. Leaves very variable 

 iu size, sessile, usually 1-3 by g-| in. (sometimes much larger, reaching 

 6-7 in. long), oblong-lanceolate, acute, entire or serrulate, rough or 

 scabrid with short appressed hairs on both sides, pale beneath, dilated 

 and with rounded auricles at the base. Heads |-| in. in diam., on long 

 slender peduncles. Invol.-bracts slender, erect, linear, acute, more or 

 less hairy and with membranous margins, the outer much the shorter. 

 Eay-flovvers 12-24, much longer than the involucre; ligules yellow, 

 narrow, 3-toothed at the apex, revolute. Pappus of ray-flowers 0, 

 of disk-flowers scanty. Achenes ^\ .^ in. long, pale, terete, sparsely 

 hairy. Fl. B. I. v. 3, p. 297 ; Trim. PI. Ceyl. v. 3, p. 33 ; Woodr. in

I have examined many of the ligulate flowers of the species, including 

 some from Wight's type-specimens, and have always found them 

 destitute of pappus. Wight in his figure (Icon. t. 1148) shews several 

 pappus-hairs on the achenes of the female flowers, but Roxburgh, 

 PI. Ind. 1. c, says tliat the female florets have no pappus, M'hile Dalzell & 

 Gibson give as a distinguishing character of the next species the presence 

 of a few pappus-hairs, thus implying their absence in this species.
