umber of species, having such widely differ 
habits, that Botanists, at an early period of their acquaintance with them, were led to create many 
supposed genera, the distinctions among which are now found to be unreal or unimportant. They, 
however, in some cases, form good sectional divisions, of which a vacant page enables us to present 
the following sketch, along with an enumeration of all the species known to us, and their more 
important synonyms :
