 their being mere varieties of each other.

10. Ooclinium villosum. DC. Prod. 5. p. 134. — French Guiana. Herb. 

 Par. n. 148 and 151. and Leprieur. 



This is without, doubt an Ooclinium. The leaves are often deeper 

 toothed than is described. 



11. Ooclinium 1 clavatum, sp. n., suffruticosum ? caule tereti striato scabri- 

 usculo, foliis oppositis distantibus linearibus trinerviis scaberrimis, panicuke 

 ramis oppositis apice subtrifidis, ramulis subtricephalis, capitulis subcylin- 

 dricis circiter 20-floris, involucri squamis imbricatis appressis striatis apice 

 obtusis brevissime appendiculatis deciduis/receptaculo obovato-clavato. — 

 British Guiana. Schomburgk, n. 165. 



The very deciduous involucrum is precisely as in Ooclinium, with 

 which this species is also connected in habit ; the receptacle, how- 

 ever, is not so decidedly oviform, being obconical in the lower part 

 and only slightly convex on the top. Amongst Eupatoria it would 

 be nearest related to the E. obscurum, DC.

15. Eupatorium ixodes, sp. n., fruticosum, glabrum, viscosum, ramis te- 

 retibus, foliis oppositis vel supremis alternis breviter petiolatis oblongis ob- 

 tusis integerrimis vel hinc inde sinuato-dentatis basi angustatis rigidis pen- 

 ninerviis, panicula? ramis alternis oppositisque apice corymbosis, capitulis 

 sessilibus pedicellatisque ovatis 25 — 30 floris, involucri squamis 4 — 5-seriatis 

 oblongo-linearibus imbricatis dorso subpuberulis, intimis apice breviter ci- 

 liatis, achseniis ad costas scabridis. — Savannahs of the Rupunoony. Schom- 

 burgk, n. 79. 



This species comes nearest to E. subobtusum, but is more glutinous, 

 the upper leaves and branches of the panicle usually alternate, and 

 the squamee of the involucre much more numerous. Flowers, as in
