GRASSES OF SLOANE *S HISTORY OF JAMAICA. 131 



The following additional species occur in the second edition of 

 Gronovius's Flora Virginica, 1762: 



Poa panicula diffusa angulis rectis, spiculis obtusis, culmo obliquo com- 

 presso. Linn. Fl. Suec. Gron. Fl. Virg. ed. 2. 13. 1762. 

 Clayton, no. 936. The specimen is Poa annua L. 



Uniola subspicata, foliis involutis rigidis. Linn. Spec. Gron. Fl. Virg. ed. 2. 

 14. 1762. 

 Clayton, no. 507. Linnaeus cites "Clayt. virg. 507" under Agrostis virginica a and 

 also under Uniola spicata.b The specimen is Sporobolus virginicus (L.) Ivunth. In 

 neither case is a Gronovius or Clayton diagnosis quoted. 



Uniola paniculata Linn. Spec. Gron. Fl. Vug. ed 2. 14. 1762. 



Clayton, no. 909. Linnaeus cites under Uniola paniculata "Uniola calycibus poly- 

 phyllis. Gron. virg. 136." Gronovius mentions this polynomial in connection with 

 his preceding species, U. calycibus diphyllis (Eragrostis megastachya). Gronovius's 

 species is without doubt the same as the Linnaean, that is, Uniola paniculata, although 

 no specimen was found. 



THE GRASSES OF SLOANE'S HISTORY OF JAMAICA. 



The grasses described by Sloane are preserved in the Sloane her- 

 barium at the British Museum of Natural History. The list given 

 below is in the same sequence as that of Chapter IV, of Sloane's 

 History of Jamaica/ entitled "Of Herbs with grassie Leaves, " d 

 from which the diagnoses are quoted. Sloane's plates are frequently 

 quoted by Linnaeus in the first edition of his Species Plantarum, but 

 in only a few cases are Sloane's specimens the types of the Linnaean 

 species. In the following list it is so stated in connection with each 

 species, if the Sloane plate is cited by Linnaeus, or if the Sloane plant 

 is the type of a Linnsean species: 



Oryza. Raii hist. 1240. 



An account of rice {Oryza sativa L.) as cultivated in Jamaica. The specimen is an 

 awned variety. 



Milium Indicum arundinaceo caule granis flavescentibus. Herm. Cat. e p. 425. 

 An account of sorghum (Sorghum vulgar e Pers.) as cultivated in Jamaica, "for Pro- 

 vision." The specimen is a form with short compact panicles. There is not enough 

 of the stem to show if it be curved. 



«Sp. PI. 63. 1753.
