REPORT ON THE BOTANY OF THE ATLANTIC ISLANDS. 45 



Morison, who appears to have first described this plant, drew up his description from 

 Bermudan plants cultivated at Hampton Court before 1699. 



This and Borrichia frutescens are the only two species of the genus ; and both species 

 are remarkable for a peculiarity in the foliage that has led to their being subdivided into 

 three or four species. Usually the leaves are clothed all over with hairs, and those of 

 Borrichia arborescens with a dense soft down ; but side' by side with plants thus clothed 

 with hairs others are occasionally found with perfectly glabrous glossy foliage. Other 

 plants occur in which some of the leaves are hairy and some quite glabrous. In all 

 cases, probably, the leaves are hairy when quite young ; and the hairs, which are clearly 

 of a very deciduous nature, are from some cause shed early where the leaves are 

 naked. Throughout its range of distribution it inhabits calcareous, rocky, or other dry 

 situations.

Linnaeus records this species from the West Indies, and cites Sloane's Chrysanthemum 

 fruticosum maritimum (Hist. Jam., i. p. 260), which probably belongs to Borrichia 

 arborescens.
