1. Sorghastrum francavillanum (Fourn.). 

 Andropogon francavillanus Fourn Mex. PI. 2: 56. L886. 

 Pinar del Rio, Wright 3896; Herradura, Baker HC 2179. 



The Sauvalle specimen has two labels, ''Sandy pine w Is < >< i .." and " Low savan- 

 nas and pinales Sept." The Wright specimen in the National Herbarium has an I 

 label. This species has a loose panicle, with slender branches; the spikelets are aboul 

 5 mm. long, light brown, sparsely pilose on the lower half; the pedicel of the upper 

 spikelet about 4 mm. lone;, awn 10 to 15 mm. long, once, or more or less twice, genicu- 

 late; blades long and folded or convolute, about 3 mm. wide. I have not seen Four- 

 nier's type of this, but his description applies to the Cuban plant. 



2. Sorghastrum setosum (Griseb.). 



A ndropogon setosus Griseb. Cat. PI. Cub. 235. L866. 

 Wright 3897. 



The specimen in Grisebach's herbarium, which is the type, lias a blank label 

 of 1865 and bears the secondary number 208. The Sauvalle Herbarium contains 

 a specimen accompanied by a similar label with no. "208" and a second of the sail e 

 kind, with no. "3897" and also a label with habitat. "Bushy savannas. Hanabana, 

 June 1." This is a duplicate type. Wright's 3897 in tin Gray Herbarium is from 

 "Bushy savannas, Hanabana, June 6." 



The inflorescence is comparatively dense; the spikelets smaller than in the pre- 

 ceding, only about 3 to 3.5 mm. long, long-pilose all over; pedicel of the upper 

 spikelet 2 to 3 mm. long; awn none or 'short and exserted 1 to 2 nun.; blades flat, 

 5 mm. wide, about 15 cm. long. 



12. RHAPHIS Lour. Fl. Cochinch. 57.2. [790. 



1. Rhaphis pauciflora (Chapm.) Nash in Small, Fl. Southeast. U.S. 67. 1903. 



Sorghum pauciflorum Chapm. Bot. Gaz. 3: 20. 1878. 



Sandy pine woods, Pinar del Rio, Wright 5895; Isle of Pines. Taylor 46. 



This is listed in Sauvalle's Flora Cubana as "Andropogon (Chrysopogon) wrightii 

 Munro," but is without description. Under this are mentioned dos. 293 and 263. 



a Holcus sorghum L. must be considered tin' type of the genus Holcus since it is 

 tin- most important economic species of the genus and further, sine, in the fifth edi- 

 tion of his Genera Plantarum, Linnaeus refers to the genus Sorgum Mich [eli] as a 

 synonym of Holcus. 



b Poranthera Raf . (Ser. bull. Hot. 1: 221. L830)hasfor its type Andropogon nutans 

 L., but the name was previously used for a genus of Euphorbiaceae i Rudge, Trans. 

 Linn. Soc. 10: 302. L811). The type species of Sorghastrum Nash is Andropogon 

 in , nun urn Miohx., which is the same as A. nutans L.
