shorter, scabrous on the two nerves, notched at the apex, sides 
hyaline ;. anthers a little longer than 0.5™™; styles 2, separate, 
inserted on the glabrous ovary. 
This Panicularia was discovered in a subalpine open boggy place in the 
woods of the Olympic mountains (elevation 1,000”), Clallam county, Wash- 
ington, August, Igo0. It is at once distinguished from P. pauciflora (Presl.) 
Kuntz, by its slender many jointed leafy stem, the uniformly small rigid 
panicle, and the very early falling of the flowers, leaving the glumes still 
attached. Of this rare species the type specimen (number 1939) is in the 
herbarium of Stanford University. 
Panicularia flaccida, n. sp.—A tall perennial, from slender 
Creeping rootstocks. Culm 1-2™ high, smooth and shining, 
5—7-jointed, rather soft and reclining. Blades as many as there 
are joints, flat, finely scabrous on both sides, flaccid, 12-15™™ 
wide, averaging 2°" long, lanceolate acuminate, with a strong 
midnerve from the base; sheaths a trifle shorter than the inter- 
nodes, glabrous, many striate ; ligule membranous, hyaline, 2-3™™ 
long, ultimately becoming lacerate. Panicle lax, subpendulous, 
15-20 long, g—-15™ in diameter; rays 2, 3, or5, usually branched 
from or below the middle, slender, lax and flexuose, slightly 
scabrous on the ultimate branches; spikelet 3-5™™ long, com- 
pressed, 5~7-flowered, soft in texture; glumes persistent after 
the breaking up of the flowers, the upper half hyaline or in age 
entirely so, nerveless, glabrous, the lower 1™™ long and obtusish, 
the upper a trifle longer and ladle-shaped; rachilla 5™ long, 
terminating in a rudimentary flower; lower palet broadly ellip- 
tical, finely scabrous on the conspicuous 5 nerves, 2.5™™ long, 
the upper margin hyaline; upper palet 2™™ long, rather broad, 
obscurely scabrous on the 2 nerves above the middle, apex 
with a shallow notch; stamens 3, with anthers 0.5™™ or a trifle 
longer ; styles 2, distinct. 
This grass is separated from P. pauciflora (Presl) Ktz. by its taller, more 
flaccid habit, pale color, and the larger lax panicle. It was collected by 
myself in a shaded boggy place in the foothills of the Olympic mountains, 
Clallam county, Washington, July, 1900. ‘Type specimen (number 1940) is 
in the herbarium of Stanford University.
