coeraleum, Sieb. Marl. 192!— 2'-6' high, flowering in the first year; heads ovoid, early 

 expanded : flowers whitish (pr blue).— Hab. Jamaica !, Hist, March, a weed in the moun- 

 tains; Antigua I, Wullschl., Dominica 1, /mr., S. Vincent I, Guild.; Trinidad I, dr.; rCubai

13. EUPATORIDM, L. 

 (Campulocliniam and Ooclininm, DC) 



Bead discoid. Involucre imbricate or 2-1-serial. Receptacle naked, glabrous, usually 

 flat. Corolla olavate or campanulate above. Achenium 5(-3)-gonal: pappus pilose.— 

 Shrubs or herbs ; heads mostly in terminal corymbs. 



The West Indian species do not admit of separating Campuloclinium : for those species 

 which present a convex or hemispherical receptacle above the involucre are too nearly re- 

 lated to others. Ooclinium, considered by Schultz Bip. Kegensb. Fl. 1850, p. 419 as the 

 type of 3. particular division of Eujiatoriacets, on account of its compressed achenia, has no 

 better claims to be distinguished ; for — 



1. I have a new Dominica Eupatorium, which, with the head of Cylindrocephala, and a 

 flat receptacle, presents 3-gonal-suboompressed achenia, exactly as Ooclinium villosum, DC, 

 of PI. Sprucean. and Hostin. ; the latter is perhaps identicad with E. urticifolium, L. fil., 

 figured by Smith. 



3. Ooclinium rigidum, DC, has the 5-gonal achenium of Eupaioriam, and would conse- 

 quently belong to Campuloclinium, while C. surinamense, Miq. (Sch. Bip. I in PI. Pockean ), 

 is Eup. YUalbce, DC. 



§ 1. Ctlindkocephala, DC. — Receptacle produced into a short cylinder between the in- 

 volticral scales, convex or flat above them. Involucre cylindrical, many-serial: scales 

 oppressed, glabrescent.

23. E. rigidum, Sw.! Suffrutescent, glabrous; stem cylindrical; leaves opposite, 

 shortly petioled, rigid, ovate or ovate-lanceolate, acuminate, 3-nerved with impressed veins 

 above, densely dotted with glands beneath, remotely serrate : serratures 2-3 on each margin; 

 corymbs few-headed : heads many-flowered, pedicellate ; receptacle convex ; involucral scales 

 oblong, blunt, striate; achenium slightly muricate. — Ooclininm, DC. — 1'-2' high; leaves' 

 18"'-8"', involucre 5"'-6"' long ; flowers violet; achenium 5-gonal, with equal sides.— Hab. 

 Jamaica !, Sw., in limestone hills of the northern districts. 



24. E. Ossseannm, DC. Shxviibj, glabrous ; branches cylindiical; leaves opposite, 

 long-petioled, rigid, ovate-lanceolate, acuminate with a bluntish point, Z-nerved with im- 

 pressed veins above, densely dotted with glands beneath, coarsely cartilaginous-serrate 

 above the snboUneate base; corymbs trichotomous ; heads many-flowered, ultimate ter- 

 nately sessile; receptacle flat ; involucral scales ovate-oblong, bluntish or blunt, subestriate; 

 achenium glabrous. — AUied to the preceding, and perhaps still more to E. macranthum, Sw., 

 of Marti;nique, said to be distinguished by 6"'-long involucres. Leaves 3"-2", involucre 3'" 

 long. — Hab. S. Vincent I, Chiild.; [Cuba]. 



25. E. puuctatum. Lam. Shrubby, glabrous; branches slightly obtuse-angled, or 

 striate ; leaves opposite, petioled, ovate or ovate-lanceolate, acuminate, triplinerved, densely 

 dotted with glands beneath, serrate ; corymbs compound : heads 10-20-flowered, pedicellate ; 

 receptacle flat ; involucral scales ovate-oblong, blunt, striate ; achenium glabrous. — Leaves 

 3"-2", involucre 4'" long.— Hab. Trinidad I, &eb. Tr. 75 ; [Guadeloupe I]. 



26. E. Isevigatum, Lam. Shrubby, glabrous; branches striate-angular ; leaves op- 

 posite, petioled, ovate (or ovate-lanceolate), pointed, S-nerved, dotted beneath with minute, 

 somewhat distant glands, serrate ; corymbs compound : heads 10-20-flowered, pedicellate, 

 (or ultimate sometimes subsessile) ; receptacle convex ; involucral scales ovate, and ovate- 

 oblong, blunt, striate, innermos' bluntish; achenium slightly scabrous on the angles. — Miq.
