spikelets pale green, or vividly 
variegated or uniformly tinged 
with dark purple 
$ §. Glumes pectinately toothed ; spikelets oblong, 
f-2 lin. long, on very fine flexuous pedicels,

panicles ; perennial 
JJSpikelets 1-1 £ lin. long, ovate-oblong to lanceolate 
(slightly oblique in 78, P. subobliquum), acute, in 
rather delicate open panicles or with the short 
ultimate divisions contracted on the primary 
branches ; lower glume acute, as long or 
almost as long as the spikelet, 3 -nerved or 
shorter to much shorter and then mostly much 
narrower than the lower valve with the lateral 
nerves evanescent ; upper glume and lower 
valve 5-, or the former 7 -nerved ; perennial 
with slender branched (often copiously) many- 
noded culms and frequently sharply reflexed 
linear to linear-lanceolate distinctly acuminate 
leaf-blades

to ovate-lanceolate ; spikelets -§-l lin. long, oblong 
to ellipsoid in small panicles, |-1 in. long with 
rigid horizontally spreading or ascending branches ; 
loosely tufted annuals or perennials, the latter 
with long trailing and rooting runners 
■♦♦Lower valve 3-nerved ; spikelets 1-14 lin. long, variously 
shaped, pubescent to villous, in delicate open panicles 
with the lowest branches pseudo-verticillate ; lowest 
glume hyaline to subhyaline, less or much less than 
half the length of the spikelet, faintly 1 -nerved; 
upper glume faintly 5-nerved (finely caudate- 
acuminate in 83, P. caudiglume ) ; annual or perennial 
with linear-lanceolate leaf- blades ... 
^ Spikelets slightly oblique to gibbous in profile, 4-1 lin. long, 
loosely scattered in delicate rigidly open panicles ; 
lower glume mostly 3-nerved, half as long to as long 
as the spikelet, in the latter case narrower than the 
lower valve to which it is appressed ; upper glume and 
lower valve 5-nerved ; weak loosely tufted annuals 
with thin soft ovate or ovate-lanceolate leaf- blades 
which are suddenly constricted and much rounded at 
the base
