GRASSES OF SLOANE’S HISTORY OF JAMAICA. 131 
The following additional species occur in the second edition of 
Gronovius’s Flora Virginica, 1762:

Uniola subspicata, foliis involutis rigidis. Linn. Spec. Gron. Fl. Virg. ed. 2. 
14. 1762, 
Clayton, no. 507. Linnzeus cites ‘‘Clayt. virg. 507” under Agrostis virginicaé and 
also under Uniola spicata.o The specimen is Sporobolus virginicus (L.) Kunth. In 
neither case is a Gronovius or Clayton diagnosis quoted. 
Uniola paniculata Linn. Spec. Gron. Fl. Virg. ed 2. 14. 1762. 
P I g 
Clayton, no. 909. Linneus 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 Linnwean, 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,’’¢ 
from which the diagnoses are quoted. Sloane’s plates are frequently 
quoted by Linneus in the first edition of his Species Plantarum, but 
in only a few cases are Sloane’s specimens the types of the Linnwan 
species. In the following list it is so stated in connection with each 
species, if the Sloane plate is cited by Linneeus, or if the Sloane plant 
is the type of a Linnean species: 
Oryza. Raii hist. 1240. 
An account of rice (Oryza sativa LL.) as cultivated in Jamaica. The specimen isan 
awned variety. 
Milium Indicum arundinaceo caule granis flavescentibus. Herm. Cat.¢ p. 425. 
An account of sorghum (Sorghum vulgare 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.
