CHILI. 



[Composites. 



ovalibus argute denticulatis, basi in petiolum latum attenuatis, paniculis terminalibus 

 foliosis, floribus parvis. 



Hab. Conception. — The florets in our specimen are unexpanded, but there is so excellent a character 

 in the beautiful close denticulation of the foliage, that we are unwilling to pass it over in silence. The 

 leaves are about three inches long, slightly woolly on both sides, paler beneath, where they are finely reticu- 

 lated, becoming gradually smaller upwards, and passing into linear bracteas among the upper flowers of the 

 panicle. It may possibly be a Baccharis. 



10. AGERATUM. Linn. 

 1. A. conyzoides ; herbaceum annuum, caule piloso, foliis ovato-oblongis obtusiusculis 

 crenatis, floribus corymbosis. Spr. — Linn. 



Hab. Conception. — Different varieties occur throughout all South America.

Hab. Coquimbo. — In the Exotic Flora it is stated that Feuillee's plant was a second species of Grcemia ; 

 but we are now disposed to unite the whole of the above synonyms. Mr. Cruckshanks finds it abundantly 

 at Valparaiso ; and at Quintero, about ten leagues farther northward, it was observed by Mrs. Graham, cover- 

 ing whole tracts of country. Mr. Cruckshanks mentions that he never understood that it was applied to 

 dyeing, but that the natives make a decoction of it, which they use instead of chamomile. 



12. BIDENS. Linn. 



1. B. bipinnata; foliis bipinnatis glabris, foliolis lanceoiatis inciso-pinnatifidis, floribus 

 corymbosis discoideis. Spr. — Linn. — Feuill. Chil. v. 2. t. 33. 



Hab. Valparaiso. — We have it also from Dr. Gillies. There is no difference of any importance, that we can 

 perceive, between the North American specimens and those in this collection : it seems to be very generally 

 diffused over South America. 



13. BACCHARIS. Linn. 



1. B. rosmarinifolia ; caule fruticoso dense folioso, foliis linearibus obtusis margine 

 revolutis resinoso-glandulosis, corymbis terminalibus densis paucifloris, involucro cylin- 

 drico imbricate 



Hab. Conception.— We possess the same, gathered at Valparaiso by Mr. Bridges, who says that all the 

 species are called Romero. It may be B. linearis, Pers., but we do not observe any of the leaves to be 

 toothed. Perhaps Persoon's character may be drawn up from more than one species of this difficult genus. 



2. B. mucronata ; caule fruticoso, foliis fasciculatis cuneatis basi attenuatis sessilibus 

 dentato-spinosis rigidis, floribus solitariis ramulos versus apicem caulis foliosos breves 

 terminantibus et ita quasi spicato-racemosis. 



Hab. Coquimbo.— The nearest species is B. uniflora, Pers., which is described as having lanceolate leaves. 

 Perhaps it is the B. banlisicefolia of Bertero in the Bulletin des Sciences Nat. 1830, p. 108, but no descrip- 

 tion of that has been published. 



3. B. obovata ; suffruticosa glabra foliis obovatis cuneatis superne profunde dentatis
