tion to Furcraea. Sec further F. Commelyni and F. spinosa, 

 below. \\'hatever "aspera" may have been it certainly was 

 not F. cubensis, Vent. 



F. ATROviRiDis, Jacobi & Goeppert in Otto, Hamb. Zeit. xxii. 

 (1866), p. 328. 



Baker (Amaryll. p. 199) reduced this to F. gigantea, Vent., 

 but Jacobi gives reasons for distinguishing " atroviridis." 



There is a plant at Kew which may be distinct from either 

 gigantea or tuberosa, and answers fairly to Jacobi's marks for 

 atroviridis, so that pending further information the name had 

 better be kept up provisionally. 



The "F. viridis" of Index Kewensis ii. 984 is based on the 

 citation of a synonym in the Biologia Centr. Amer., and re- 

 lates to F. atroviridis, Jacobi & Goeppert. 



F. Barilletti, Jacobi in Abhandl. Schles. Gescllsch. 1869, 

 p. 166. 



Apparently a garden variation of gigantea or tuberosa, and 

 unless authentic specimens can be produced for examination 

 the name should be abandoned. 



F. Commelyni, Kunth Enum. v. 842. 



This is the Agave Commelini of Salm-Dyck in "Annota- 

 tiones Botanicac" to the "Hortus Dyckensis," (1834), p. 301, 

 which was expressly referred by that author to t. 19, vol. iii. 

 of the Hortus Amstelodamensis (i. e. F. tuberosa Ait. in the 

 writer's view); but Jacobi, who had seen the original speci- 

 men at Schloss Dyck, pointed out certain differences, and the 

 probability seems to be that it was really gigantea, unless in- 

 deed it was the " flavoviridis'^ of Hooker in Bot. Mag. 5163 

 (1860). The succulent collection of the Dyck Garden was 

 dispersed after the demise of its founder; a few descendants 

 are preserved of certain species, but the writer could not 

 trace "A. Commelini"'^ among them. 



* In the " Annotationes " it was proposed to restrict Furcraea to the 

 single species loiigaeva, Zuccarini.
