The reversed position of the solitary spikelets (in which the first 
glume is wanting) and the racemes aggregated at the summit of 
the culms place our plant in the section Axonopus of Paspa- 
lum and because this section being accepted by American autors 
as a valid genus our species must be named Axonopus plumo- 
sus, related to the Brasileen Paspalum comans, TRIN., also 
a member of the Axonopus group and therefore named by me 
Axonopus comans. The latter is distinguished from A xono- 
pus plumosus as follows: 
Spikelets 5 mm long, glabrous, towards the top somewhat hairy, 
without long hairs at the base; lemma 4 mm long, at the top bar- 
bulate, pedicels of the spikelets strongly compressed, at both sides 
with a small prolongation; there is no distinct callus. — Axonopus 
comans, (TniN.) HENR.. ] 
Spikelets 4 mm long, along the margins strongly hairy with long 
soft hairs, at the base with a circle of long hairs, lemma 3 mm 
long or slightly longer, at the top with a tuft of long hairs, pedi- 
cels not so strongly compressed, slightly enlarged, cupuliform, 
without prolongation; the callus is more or less distinct. Axonopus 
plumosus, HENR.. | 
The only specimen of Paspalum comans I saw, is a plant 
from the same locality, collected by. BALANSA (no. 104) thus deter- 
minated by myself. This number is also named Paspalum 
comans by Prof. Mez, but he gave the same name to the 
Balansa plant numbered no. 105, („communication by letter”). 
After having compared the two plants with the original descrip- 
tion of Paspalum comans, Trin. in DoErr, Flora Brasiliensis 
P 109, I concluded, that only the number 104 is identical with 
this species, the number 105, the basis of my new species differing 
om this one as noted above.
