There has been much confusion in the specimens distributed by Wright unde 
numbers 3453, 3454, and 3461. The Grisebach specimen of the above species, which 
is the type of his variety, is labeled * ‘Cya oce. Wr. 1863, 900=3454."’ No. 3453 
is P. neuranthum. As distributed in various herbaria, however, 1’. Jusiforme occurs 
in part of nos, 3453, 3454, and 3461. With these are various mixtures of P. neu- 
ranthum, P. pauciciliatum, and P. lancearium.

No. 761 of Wright in the National Herbarium is labeled ‘‘Wet, around ponds, 
Hanabana, June 5.” The Grisebach specimen is from eastern Cuba in 1860 and 
is labeled ‘‘Bunches beside water holes. Palma Sola, July 19. 99=761." Per- 
soon’s name is based on Panicum brizoides Lam., as he quotes Lamarck’s di agnosis 
and cites his name as synonym. At Florence there is an authentic specimen of this 
sent by Lamarck, collected in Mauritius by Commerson. The specimen of Pan- 
icum brizoides in the Linnean Herbarium is Echinochloa colona (L.) Link.  Doelle 
takes up Paspalum appressum Lam. Tabl. Eneyel. 176. 1791, transferring it to Pan- 
icum, but this is invalidated by Panicum appressum Forsk. FI. Aegypt. Arab. 20. 
1775, and by P. appressum Kunth, Enum, 1: 84. 1833.

barium. Wright’s 757 in the Gray Herbarium is from “La Perla, along roadsides.”’ 
The Grisebach specimen is from eastern Cuba, no. 757. P. Lindenii Griseb. is a 
typonym of P. obtusiflorum Rich., both being based on Linden 2143, which is in 
the Paris Herbarium. ,

The main stem creeps along the ground, throwing up flowering branches a foot 
or so high. There are two Wright specimens of this in the Grisebach Herbarium, 
both from western Cuba, 1863, one numbered ‘‘889—345 57,°’ the other 9413457,"
