separate genera, each consisting of one or, at most, very few 

 species. Ilamjyea has one S23ecies in Mexico and one in New 

 Grenada, while Matisia appears not to extend beyond the lower 

 eastern, northern, and western slopes of the Andes of Is^cw Gre- 

 nada. To the same tribe belong seven other genera (of which 

 four are nionotypic) Avhose range is confined to limited areas in 

 tropical America, and an eqnal number, of which also four arc 

 monotypic, are found in the tropics of the Old AVorld. 



JIasseJtia, with only two or three species, is a genus of Til iacece 



which appears to be confined to New Grenada ; but I am not sure 

 that it extends to the Pacific coast. The allied genus Procl'ia 

 has a wide range in tropical America. 



FeUicz€7'a, a monotypic genus of Ternstromiacece^ is a curious 

 tree with the habit of the mangroves, and, like that tribe, in- 

 habits the muddy shores of the Pacific from Buenaventura 

 northward to Central America. 



Cespedesia and Godoya — the former with four, the latter with 

 two species — are genera of Oclinacece^ whose range is said to be 

 confined to Northern Peru and New Grenada, but which doubt- 

 less extend to the lower region of Ecuador. Along with four 

 other allied genera inhabiting Guiana and Northern Brazil, 

 they form the tribe LuxemlergicB^ which is strictly confined to 

 equatorial America. 



Fllosj^crmay ChisieUay and Bcdhoa are monotypic genera, nearly 

 allied to Clusia, which are confined to the Pacific slopes of the 

 Andes of New Grenada. The whole tribe of Clusiecv is confined 

 to tropical, and mainly to equatorial, America. Although most of 

 the species inhabit the warmer zone they have a very limited 

 range, and several of them are mountain species inhabiting the 

 middle zone of the Andes, between GOOO and 9000 feet above the 

 sea. To this category, indeed, belongs Clusiella, which has not 

 Leen found below the level of GOOO feet. 



It is apparent from these facts that, if we may judge of the 

 tropical flora of New Grenada from the portion hitherto ])nb- 

 lished, it is not characterized by the presence of many peculiar 

 types of vegetation, ^'ith the single exception of FelUciera, the 

 few endemic genera are nearly allied to others inhabiting other 

 parts of tropical America, and belong to trihcs which arc else- 

 where marked by the tendency to variation in portions of their 

 structure that arc held to constitute generic cliaracters. Several 

 of the generic types regarded as characteristic of the western side
