Panicum clutei Nash, Bull. Torrey Club 26: 569. 1899. ‘‘ Pine-barrens of southern 
New Jersey. Collected by Mr. W. N. Clute * * * ona trip from Tuckerton to 
Atsion, July 3-6, 1899.”’ The type, in Nash’s herbarium, consists of three stout 
culms with mature panicles. The lowermost nodes are sparsely bearded, the upper 
glabrous, the lowermost sheaths sparsely soft-pilose as in the type of P. mattamus- _ 
keetense. The blades are puberulent or pilose on the auricles and the dense ligule is 
0.5 mim. long. 
DESCRIPTION. 
Vernal form similar in color, size, and habit to P. mattamuskeetense, but more nearly 
glabrous, only the lowermost nodes, sheaths, and blades velvety, the puberulent 
ring at the summit of the sheath less dense or wanting; paniclessimilar, on the average 
smaller; spikelets 2.2 to 2.3 mm. long, 1 mm. wide, 
indistinguishable from the smaller spikelets of P. 
mattamuskeetense; fruit the same size and shape. 
Autumnal form stiffly erect, branching from the 
lower and middle nodes before the maturity of the 
primary panicles, the earlier branches nearly equal- 
ing the primary culms, the later branches shorter, 
somewhat crowded, the reduced blades spreading. 
ree ay op enined leon type This form is) but doubtfully distinguished from P. 
specimen) mattamuskeetense. ‘The division is here made on the 
nearly glabrous character of P. clutei, and spikelets 
not over 2.3 mm. long, but a few of the specimens are about as referable to one species as 
to the other. One specimen, Chase 3590, has the smaller panicles and more numerous 
branches of P. clutei, but the two or three lower sheaths and _ blades are velvety, 
while Chase 3793 has spikelets but 2.1mm. long and upper nodes puberulent only, but 
is densely velvety below. The latter specimen is referred to P. mattamuskeetense 
because its vernal form (Chase 37444) 
is more like the type of P. matta- 
muskeetense than like that of P. clutet. 
One specimen, Chase 3242, has glabrous 
spikelets.
