Egypt, Africa, and Australia are all very different. A variety of P. glaucumfrom 
Africa looks like P. hians, but the rhizome is woody and covered with inflated, 
Panicum melicarium Michx. This is P. hians Elliott. Some specimens are 
labeled P. milioides ‘ses and Nees ab Esenb.; also P. miliare, the last from 
New Orleans. . 
Panicum fuscum Sw. A large plant with pe and broad leaves. The spikelets are 4 
obtuse, chestnut-colored and arranged on the lower face of the long branches. 
he panicle is rather contracted, aiit like that of Professor Scribner's 
specimen of P. agrostoides. Identical with P. am are P. Pics ans Swtz., 
and P. fusco-rubrum or P. fusco-rubens of L 
Panicum cognatum Schult. There is only one specimen named P. divergens Ell., 
but supposed to be identical with P. cogna- 
tum, and this specimen represents a true P. 
autumnale Bose. 
Panicum latifolium L. Some of the specimens 
are labeled ** P. walteri Poir., but none o 
e speci 
a seems only to bea small ie of 555 dni 
. Itis from Herb. Desf., New York. 
Panicum ensifolium Ell. Pret New Orleans 
is P. microcarpon Muhl. Some others are 
E 
from Engelmann's herbarium, but are only 
small individuals of P. microcarpo 
Panicum ae oides Muhlbg. This 4 is € 
with P. agrostidiforme of Lam 4 
Som 
labeled P. agrostoides Sprgl., »us these iro 
are P. elongatum of 3 
Panicum scoparium Lam. Beyrich's specimens 
agree with those of Professor Scribner. 
Panicum microcarpon Muhlbg. A few speci- 
mens from Curtiss's North American Plants, 
No.3599; these are, however, very different 
xem the form I have found in Brookland, 
, having very short and narrow leaves 
far seem rather to belong to a form of P. 
sphærocarpon. 
Panicum setaceum Muhlbg. (Fig. 9.) The 
specimen is from Hooker's nw and

pubes Ma. P (Willd: och. odios leaves are rather rigid, involute, sul ciliate, 
with hairy sheaths; otherwise the plant is 
smoo re is no doubt that this speci- 
men is the autumnal stage of some A Panicum; but which? 
and is from Hooker’s herbarium. On the label «P. pubescens” is written. 
Panicum lanuginosum Ell. This species can not be determined from the herbarium 
material, since the cover contains more than one species. They are the 
foilowing: 
P. pubescens Lam. A true P. epherroe ocarpon, but out of flower, from Mexico. 
P. $ Michx. A low, hairy plant, somewhat like P. anion um. 
P. LEE P. pubescens Michx. agrees with this and resembles P. ciliati-
