BOTANY OF WESTERN INDIA. 225 
Brickellia, Ell. (including Bulbostylis, DC.), is in like manner dis- 
tinguished by its terete and striate or 10-costate achenia: in no other 
way can the line be drawn between it and Hupatorium. * This excludes 
I believe all of Gardner’s Brazilian Bulbostyles ; also De Candolle’s 
B. glabra, B. spinaciafolia, B.? pauciflora, and B. triangularis (the 
latter, perhaps, a Carphephorus). B. annua, Nutt. Pl. Gambell., is not 
even an Eupatoriaceous plant. I know, however, about twenty-six 
genuine, chiefly Mexican and New Mexican, species, several of which 
are yet unpublished ;* besides three or four species of Clavigera, DC., 
which must evidently be reduced to a section of Brickellia; the more 
or less barbellate pappus not affording an adequate or sufficiently 
well-marked generic character.+ ` 
Tan. V. Dissothrix Gardneri:—natural size. Fig. 1. A capitulum 
enlarged. 2. An involucral scale. 3. A flower. 4. Corolla laid open. 
5. A stamen. 6. Achænium and pappus. 7. One of the larger and 
one of the smaller setze of the pappus :—all the dissections more or less 
magnified.
