 Menzies, in his voyage with Capt. Vancouver, and existing in several her- 

 baria to which he liberally presented it. It was, therefore, a matter of 

 great astonishment to me, to find the same genus in a plant of Jamaica, 

 to which Dr. M'Fadyen directed my attention about four years ago, and 

 which is here represented. Mexico, however, which may be reckoned 

 an intermediate country, is now known, by the exertions of Mr. Hartweg, 

 to produce three other species, which are described by Mr. Bentham in 

 his excellent PlantcB Hartwegiancs. Mr. Skinner has lately sent me a 

 species, in fruit only, from Guatemala." Hook. — A portion of the volume

 sea.
