 C. trifoliata be excluded ; but the sp. and var. 

 are numerous, not well distinguished and like so 

 many domestic trees in great perplexity, Du- 

 tour, Risso, Buchanan, Loureiro &c have men- 

 tioned over 100 varieties, several so striking as 

 to be specific deviations : having seen many 

 alive I mean to indicate some of these real new 

 species.
