Diese Art und das oben beschriebene P. falcifolium Schltr. zeichnen 
sich in der Gattung durch ihre sehr kleinen Dimensionen und die 
wenigblütigen Infloreszenzen aus. Sie kommen dem P. cristallium Ldl. 
am nächsten. 
LXXXIL Andropogon fasciculatum (L.) Thellung. 
Von A. S. Hitchcock, Washington. 
(Originalarbeit.) 
In a recent article on ,Combinationes novae*!) Thellung pub- 
lishes Chloris fasciculata (L.) Thell. based upon Andropogon fasciculatum L. 
Sp. Pl., 1753, and applies this name to Chloris radiata Swartz. As the 
conclusions reached by Dr. Thellung are different from those previ- 
ously published by myself?) I take this opportunity to state my reasons 
for rejecting the Linnaean name for the Swartzian plant. 
Andropogon fasciculatum was originally published as follows?): 
,Andropogon (fasciculatum) spicis digitatis plurimis erectiusculis 
articulatis laevibus: flosculis utrinque aristatis. 
Gramen Dactylon indicum, spicis villosis subrubescentibus. — 
Moris. hist., II, p. 185 s. 8, t. 8, f. 15. 
Gramen Dactylon elatius, spicis plurimis tomentosis. — Sloan. 
jam, 38. hist Lp HIE, 0.05, 1 3. — 
Habitat in Indiis. — Spieae in meis speciminibus glabrae 
sunt.“ 
The problem is to determine upon what the name 4. fasciculatum 
was founded or to what plant Linnaeus intended to apply the name. 
In the terms ofthe nomenclatorial technology adopted by many American 
botanists, what is the type specimen of Andropogon fascicuatum? The 
impression prevails among some European botanists that American bo- 
tanists who discuss type specimens, consider the specimens in the Lin-
