142 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
either Milium compressum Sw. or Axonopus aureus Beauv. I believe the former 
should be taken as the type, though [ think the two species are congeneric. Swartz 
species then should be known as Avonopus compressus (Sw.) Beauv. 
Milium paniceum Sw. Prod. 24. 1788. 
The type specimen is Syntherisma jiliformis (1..) Nash (Panicum filiforme 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, 4898 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 (1..) Chase (Andropogon tnsilare 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 granularis 1. The specimen belongs to this species, 
i.e., Hackelochloa granilaris (.) Kuntze. 
Manisuris myuros I.. 
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 LL. 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® 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 LL. Mant. 2: 302. 1771 
No specimen of this could be found in the Swartz herbarium. 
Chloris virgata Sw. Il. 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.”
