biseriale, sub-9-phyllum foliolis cuneato-rotiindatis. StyU 

 disci rami cono brevi carnoso glabriusciilo apiculato superati. 

 Aclienium teti-agoiimn,basi longe attenuatum, glabiiiisciiluin. 

 Pappi paleae 8 — 10, ciineato-obovatae, sequilongae, latitudine 

 ijia?qiiales, apice obtiisae, vel truncalae et eroso-dentata?, cor- 

 iieo-rnembranaceai. — Perliaps the genus Bahia ought to be 

 restricted to this plant. B. artemisicefolia, and probably all 

 the other species from California and Mexico have truncated 

 styles, as Lessing indeed dei^nas, Bahia, and belong to Eri- 

 ophyllum. Lag,, from which Trichophyllum, Nutt., is not dis- 

 tinct. EriopJi. trolliifolium, having a pappus of 4 acute paleae, 

 seems to belong to Hymenoxys.

 corneo-membranacea?, pinnatifulo-striatae, eroso-denticulatae, 

 — Herba annua pusilla glabra apice corymbose ramosa. Folia 

 inferiora opposita, sitperiora alterna, subpedatim secta, seginen-

1169. (1.) A. pusillus, (H. et A.) — Coquimbo, Cuming, 

 (n. 885.) — This genus differs from Achyropappus, in the form 

 of the style, the want of a ray, and habit ; from Florestina by 

 the absence of the subulate hairy appendages to the style; 

 and from Hymenopappus by the involucre, tiie style, and the 

 achenia. In character it is most allied to the original Bahia^ 

 but there is no ray, and the habit is totally dissimilar,
