44 ME. J. BALL OlS" THE FLORA 



leaves are slightly toothed towards the summit, oblong-lanceolate, 

 the lower opposite, tapering at the base to a very short petiole, 

 the upper alternate and sessile. The heads of flowers are in a 

 compact dense corymb.

 Chicla! Upper valley of the Eimac! There can, I think, be 

 no doubt that the form distinguished by Schultz must be referred 

 as a variety to the cosmopolitan Linnean species. 



Baccharis GEis-iSTELLOiDES, Pers., var. ALPiKA. Above 

 Casapalta ! A dwarf form of a species widely diifused in South 

 America. 



Bacckakis ALPiis'A, I£. B, jBT., var, sEEPTLLiroLiA, Wedd. ChL 

 And. Above Casapalta ! 



Bacchahts c^spitosa, Per5. Above Casapalta! This often 

 much resembles the last species, but is, I believe, truly distinct. 



Bacchahis ? Common about Chicla, forming evergreen 



bushes from 3 to 6 feet in height. This plant is intermediate in 

 appearance and structure between Baccliaris obovata^ H. B. K., 

 and jB. Chilco^ 11. B. K. ; but without further observation, I do 

 not venture to unite those species under a single name. It is 

 remarkable that, excepting only the moist hot equatorial zone, 

 the western side of the American continent, from California to 

 the Straits of Magellan, should almost everywhere produce some 

 forms of Baccliaris belonging to this group differing very slightly 

 in structure and appearance. Although I have endeavoured to 

 make myself familiar with their distinctive characters, I doubt 

 whether if I were to see growing together the bushes which I 

 have observed in their native homes at Monterey in California, at 

 Arica in Peru, at Valparaiso in Chili, and at Sandy Point in the 

 Magellan Straits, I should at once be able to identify them. In 

 this great and protean genus, so largely developed in South 

 America, there is room for prolonged study and observation by 

 the monoOTapher of the futi\re. 



AcHYROCLTXE SATunEioiDES, DC Var. foliis angustissimis 

 velutinis ? Chicla ! This apparently agrees with an unnamed 

 specimen in Kew Herbarium, collected in New Grranada at a 

 height of about 10,000 feet.
