Flowering season for this species is from March through August; fruits are present in 
December, January, and April. The type of vegetation where this species grows is pine forest, but 
it can be found also in secondary forest, between an altitude of 950 - 1500 (2000) m in Cuba and 
Dominican Republic. In Mexico, it is found at lower altitudes, between 20 (?) - 100 m. 
As considered here, C. grisebachii differs from C. costaricanum, its closest 
morphological relative, by having fruit pedicels narrow turbinate from top to bottom, branchings 
of inflorescence with terminal dichasia sessile, frequently reduced in number of flowers, looking 
glomerulate, and domatia trichomes mostly parallel to leaf surface; as opposed to fruit pedicels
