complete variance with Lagasca’s description. The genus Azo- 
nopus, Beauv., sometimes given as a synonym of Cabrera, because : 
Beauvois had suggested that P. aureum might possibly be a con- 
gener, was founded on various heterogeneous species of Paspalum 
and Panicum; and the name has to be wholly expunged. 
Anastr ‘ophus, our third section, was proposed as a genus under 
that name by Schlechtendahl, and includes Nees’s section Digt- 
tariee or Doell’s Emprosthion. It is characterized by the posi- 
tion of the spikelets on the alternate margins of the narrow, 
somewhat flexuose rhachis of the spike, so as to be rather di- 
stichous than seeund, and by their direction, the back of the flower- 
ing glume and of the lower empty one being turned outwards or 
away from the rhachis. The spikes are also generally several 
close together at the end of the peduncle, as in the section Digi- 
taria of Panicum, suggesting to Nees his sectional name, which, 
however, is inconvenient as being adjective in form, and too liable 
to be confounded with the true Digitaria. Some of the species 
have, like Cabrera, long cilia on the spikes, but have otherwise all 
the charaeters of Anastrophus, of which they might form a sub- 
section under the name of Lappagopsis, given by Steudel to the 
P. dissitiflorum, Triu., which he proposed as a distinct genus. The 
several species which we would include in the subsection show 8 
curious diversity in the position of the cilia: in P. fastigiatum, 
Nees, they are long on the empty glumes, none on the rhachis; 
in P. senescens, Nees, short on the empty glumes, long on the 
rhachis; in P. dissitiflorum, Trin., long both on the rhachis and 
on the empty glumes; and in a few other species, referred by 
Nees and by Doell to Cabrera, although without the peculiar 
characters of Lagasca's genus, the rhachis alone is fringed with 
long cilia, the glumes having none. 
Paspalum saccharoides, Trin., referred by Kunth to Panicum, 
is one of those small-flowered species which seem to connect Pas- 
palum with Panicum (Digitaria), whilst the long silky hairs of the 
spikes and the consistence of the glumes show an approach to the 
Andropogonee (Saccharee). The arrangement of the spikelets 
along the rhachis, the number of glumes, &c. show a nearer 
ew to Paspalum than to any other genus. 
3. ANTILENANTIA, Beauv. (Aulaxanthus, Ell.), was founded upon 
two North-American species, ; with the hairy inflorescence and 
membranous glumes of the section Trichachne of Panicum, but 
without the small lowest glume of that genus; and the second
