142 CONTRIBUTIONS FKOM THE NATIONAL HERBARIUM. 



either Milium compressum Sw. or Axonopus aureus Beauv. I believe the former 

 should be taken as the type, though I think the two species are congeneric. Swartz 

 species then should be known as Axonopus compressus (Sw.) Beauv. 



Milium, paniceum Sw. Prod. 24. 1788. 



The type specimen is Syntherisma filiformis (L.) Nash (Panicum Jilt forme L.). 



Milium digitatum Sw. Prod. 24. 1788. 



The type specimen is Syntherisma setosa (Desv. ) Nash as described in Nash's review 

 of Syntherisma." The long-exserted peduncles bear 2 to 4 slender spikes, with narrow 

 rachis. It is well matched by Heller no. 4398 from Porto Rico and Wright no. 764 

 from Cuba. The spikelets are narrow, slightly exceeding 2 mm. in length. Swartz's 

 name is earlier than the other names for this, hence the species becomes Syntherisma 

 digitata (Sw.). 



Milium villosum Sw. Prod. 24. 1788. 



The type specimen is Valota insularis (L. ) Chase (Andropogon insulare L.; Panicum 

 leucophacum H. B. K.). 



Agrostis purpurascens Sw. Prod. 25. 1788. 



The type specimen is Sporobolus purpurascens (Sw. ) Hamilt., as described in Grise- 

 bach's Flora. 



Manisuris granularis Sw. Prod. 25. 1788. 



This is based on Cenchrus granulans L. The specimen belongs to this species, 

 i. e.. Hackelochloa granularis (L.) Kuntze. 



Manisuris myuros L. 



The specimen is a Rottboellia from the East Indies. Swartz gives no locality in the 

 Prodromus. 



Chloris cruciata Sw. Prod. 25. 1788. 



This is based on Agrostis cruciata L. The specimen belongs to this species. 



Chloris ciliata Sw. Prod. 25. 1788. 



The type specimen belongs to this species as generally understood. It is well 

 matched by Curtiss no. 600 from Cuba. 



Chloris petraea Sw. Prod. 25. 1788. 



The type specimen belongs to this species as generally understood, and as described 

 in Grisebach's Flora. Doell b changes the name of this to C. swartziana on account of 

 C. petraea Thunb., which, however, is a later name. 



Chloris polydactyla Sw. Prod. 26. 1788. 



This is based on Andropogon polydactylon L. The specimen belongs to that species. 



Chloris radiata Sw. Prod. 26. 1788. £ 



This is based on Agrostis radiata L. The specimen belongs to that species. ' 



Chloris barbata Sw. Fl. Ind. Occ. 1: 200. 1797. 

 This is based on Andropogon barbatum L. Mant. 2: 302. 1771. 

 No specimen of this could be found in the Swartz herbarium. 



Chloris virgata Sw. Fl. Ind. Occ. 1: 203. 1797. 



There is no specimen of this. A cover was found marked with the name, but con- 

 taining nothing, and upon which some one has added an "0." From the description 

 it would appear to be the species represented by plate 18 in Martius's Flora Brasiliensis, 

 vol. 2, part 3. Grisebach includes it under C. radiata in his Flora, but from this 

 species it is excluded by the statement in Swartz's diagnosis "corollina exteriore 

 gibbosa, dorso apiceque ciliata."
