Verhesina microptera, DC, only a variety of V. Virginica, L. (58). 



Stemmodontia scaberrima, Cass, in Diet. Sci. Nat. 46, p. 407. Buph- 

 thalmum scabrum, Cav. Wedelia hispida, H. B. K. Lipochceta 

 Texana, Torr. & Gray, Fl. N. Am. & Bot. Mex. Bound, p. 92. Wirt- 

 genia Texana, Schultz Bip. in Bot. Voy. Herald, p. 304. A form 

 with small heads (89). — Doubtless this is the plant upon which 

 Cassini founded his genus Stemmodontia, in the description of which 

 he even indicates the appendages on each side of the base of the 

 achenium. So that Wirtgenia of Schultz must give place to Stemmo- 

 dontia, Cass. 



An undetermined, apparently new Composita, with the aspect and 

 fertile ligules of Verhesina, but with a cliaffy pappus (78). Also Oli- 

 gogye Tampicana, DC. (85). 



Dysodia puhescens. Lag., a mere variety of D. chrysanthemoides, Lag. 

 (379) ; Tagetes lucida, Cav. (94), and T. peduncidaris, Lag. (377) ; 

 and a variety of Porophyllum ellipticum, Cav. (75). 



Galea urticcefolia, DC. (96)*; Tridax procumhens, L. (61) ; Heleniam 

 microcephalum, DC. (76) ; also a remarkable plant, which, not to multi- 

 ply genera on single species, I am disposed to append to BaJiia, viz. : — 



Bahia ? {Anisostemma : eligulata, anisopappa) nepetcefolia (sp. nov.) : 

 erecta, tomcntella, corymboso-ramosa, foliis oppositis deltoideo-ovatis v. 

 subcordatis grosse obtuseque dentatis incisisve subtus albo-tomentosis, 

 petiolo gracili ; capitulis conferte corymbosis ; involucri squamis ovali- 

 lanceolatis ; corollis albis ; pappi paleis 3 ad latus exterius linearibus 

 tubum corollte ada^quantibus, 3-4 ad latus interius perbrevibus. — 

 Folia 1 - 2-pollicaria, petiolo ^-poUicari. Pedicelli 4-12 lin. longi. 

 Capitula 4 lin. longa, multiflora, homogama. Involucrum laxum, squa- 

 mis circ. 12 utrinque angustatis dorso carinatis extus tomentulosis disco 

 paullo brevioribus. Achenia gracilia, basi longe attenuata, hirsuta, 

 corollis omnibus tubulosis 5-dentatis (ut videtur albis) longiora. Pappi 

 paleae fere enerves (65). — Technically this might well enough be taken 

 as the type of a new genus ; but if it had rays it would certainly be re- 

 ferred to Bahia proper, of which it has the habit and whole general struc- 

 ture. The white, or possibly flesh-colored flowers, with a glandular tube, 

 &c., show an affinity to Florestina ; — but the opposite leaves, and the 

 capitellate tips of the branches of the style (which accord with Bahia § 

 Eriophyllum) are quite different. The extraordinary reduction of the 

 paleae of the pappus on the side toward the centre of the receptacle is 

 constant.
