WEST INDIAN GRASSES DESCRIBED BY SWARTZ, 185 
In addition to the grasses included in the above chapter, Sloane 
described four others. Two are from Madeira (Tab. 2. Figs. 4, 5, 6). 
The other two are described in an account of the plants of the island 
of Nieves [Nevis]. 
Gramen dactylon bicorne tomentosum maximum, spicis numerosissimis. 
Cat. pl. Jam. p. 33. Table 14 [the plate is numbered 15]. 
This is Andropogon bicorne L. The diagnosis is cited by Linnzeus under that 
species.? In the second edition the plate is also cited. 
Gramen avenaceum, panicula minus sparsa, glumis alba sericea lanugine 
obductis. Cat. pl. Jam. p. 35. Tab. 1. Fig. 2. 
This is cited by Linnzeus under Andropogon insulare.¢ It is Valota insularis (1..) 
Chase (Panicum leucophaeum H. B. K.). 
THE WEST INDIAN GRASSES DESCRIBED BY SWARTZ. 
Olof Swartz collected in the West Indies, especially Jamaica, from 
1783 to 1787. His collections are preserved in the Natural History 
Museum at Stockholm.’ [is first account of his West India plants 
was published in 1788 in a small work entitled ‘‘Nova Genera et 
Species Plantarum, seu Prodromus Descriptionum Vegetabilium 
Maximam Partem Incognitorum quae sub Itinere in Indiam Occi- 
dentalem annis 1783-87 Digessit Olof Swartz.’ This work contains 
the diagnoses of most of his new species of grasses. A few more 
appear later in his more comprehensive work entitled ‘‘Flora Indiae 
Occidentalis.” © In the later work the descriptions are considerably 
amplified and often aid in identifying his earlier diagnoses. A few 
of his tvpes of grasses are missing from his herbarium, ‘but i in all cases 
I have been able to identify the corresponding species from his 
descriptions or from authentic specimens distributed by Swartz to 
other herbaria, such as those of Munich and Madrid. In this 
article the species accredited to Swartz and published by Wikstrém 
in Adnotationes Botanicae (1829) have not been considered except 
when these are based on American material. 
Clyra pauciflora Sw. Prod. 21. 1788. 
The type specimen, labeled “Jamaica FI. ind. occ.,”’ belongs to this species as 
generally understood. 
Olyra paniculata Sw. Prod. 21. 1788. 
The type specimen is Olyra latifolia L. Swartz gives Linnzeus’s name as synonym. 
Sacharum polystachyon Sw. Prod. 21. 1788. 
No specimen of this could be found, but it is without doubt the species as generally 
understood; that is, Paspalum saccharoides Nees, as described in Martius’s Flora Bra-

Carl Mez, who kindly allowed me to examine them at his herbarium in Halle.
