88 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM, 
inflorescence 20 cm. long or less, much shorter than the leaves, nearly naked, bearing 
only 1 or 2 much reduced thin pale leaves, paniculate but only sparingly branched, the 
branches angled, glabrous; spikelets solitary, on peduncles 1.5 to 3 mm. long; empty 
scales several, nearly white, hyaline, lanceolate or oblong, acute, with short subulate 
tips, glabrous except for the scaberulous midnerve; bristles of the involucre 6, white, 
scaberulous; style branches very short; fruit not seen. 
Type in the U. 8. National Herbarium, no. 679431, collected on high hills back of 
Puerto Obaldia, on the San Blas Coast, Panama, August, 1911, by H. Pittier (no. 4307). 
In general appearance this is very unlike any other species of which material or 
descriptions have been seen. Its broad, elongated, silvery leaves and the very short 
inflorescence, nearly leafless and bearing but few spikelets, will enable one to recog- 
nize it readily. 
Scleria hitchcockii Standley, sp. nov. 
Underground parts not seen; plants slender, about 70 cm. high, rather sparingly 
leafy; culms triquetrous, sharply angled, striate, yellowish green, obscurely scaberu- 
lous; sheaths closely investing the culms and nearly covering them, 3 to 5 cm, long, 
sharply angled, striate, glabrous, or hirsutulous near the summit; ligule very short, 
about 1 mm. long, truncate, hirsute; leaf blades 12 to 18 cm. long, narrow, 2 to 4mm. 
wide, yellowish green, acute, conspicuously nerved, nearly glabrous, but often 
hirsute-ciliate on the margins and on the midvein beneath; inflorescence much 
exserted, on a slender peduncle; panicle about 11 cm. long, composed of few very 
slender spikes, the branches short-ciliate on the angles; bract subtending the inflores- 
cence 3.5 cm. long, very narrow; spikelets in sessile fascicles of 2, each consisting of 
one fertile and one sterile flower; glumes of the fertile flower about 2 mm. long, reddish 
brown, ovate, oblong-ovate, or lanceolate, thin, strongly keeled, the midnerve extended 
as a short awn; glumes of the sterile flowers slightly longer, about 3 mm. long, nar- 
rower; achenes smooth and shining, white, spherical or depressed, 1.2 mm. in diameter, 
disk fused with the achenes as a short thick stipe. 
Type in the U.S. National Herbarium, no. 678393, collected on a grassy hillside in 
the foothills near El Boquete, Province of Chiriqui, Panama, altitude 1,000 to 1,300 
meters, September 28 to October 7, 1911, by A. 8. Hitchcock (no. 8326). 
The proposed species is related to Scleria lithosperma, but differs conspicuously in the 
slender branches, short scales of the flowers, and small, depressed achenes.

NEW AMARANTHACEAE FROM TROPICAL NORTH AMERICA. 
Recently the writer has been engaged in monographing the family 
Amaranthaceae for the North American Flora. In a group to which 
so little attention had been given it was to be expected that more
