^HE genus Tilia consists of timber trees, with mellifluous flowers, 

 with a remarkable bractea attached to the peduncle of each of the 

 cymes of the flowers. The number of species varies, according to 

 the opinion of botanists, from two to ten. As there is great uncer- 

 tainty respecting the number, owing to the imperfect manner in 

 which several of them have been heretofore described, we shall 

 adopt only two species, and include them all under Tilia europsea, and ameri- 

 cana. The most obvious external differential characteristics of these two spe- 

 cies appear to be, that the former have regularly cordate, and the latter, obliquely 

 cordate leaves.
