original publication Dr. Gray evidently intended breviflora to 
apply to the shorter-leaved forms of the viscidly glandular south- 
western P. longifolia, var. Stansburyt, such as illustrated by No. 
896 of the 4oth parallel collection, and hence drevzfolia is not to 
be regarded as a synonym of the species here proposed, although — 
Dr. Gray subsequently so-named Mr. Jenney’s Black Hills speci- 
mens here referred to P. Kelseyz. 
The status of Stansbury? as a variety of P. longifolia does 
not appear to me to be satisfactory. PP. longifolia is a very nar- 
row-leaved plant, almost glabrous throughout, and is of north- 
western range. Stansburyi is viscidly glandular, with broader 
leaves and of southwestern distribution. Types of both are in 
our herbarium. 
I am indebted to Dr. B. L. Robinson for a comparison of my 
specimens with those in the Gray herbarium. 
CYPERUS DIANDRUS, Torr., var. ELONGATUS N. var. 
Spikelets linear, acute, slender, 2-2.5 cm. long; scales, oF 
some of them, brown-margined as in var. castaneus. 
This plant was collected in 1865 at Summit, N. J., by Mr. 
Wm. H. Leggett, and again last year by Mr. E. P. Bicknell at 
Van Cortlandt, N. Y. Its much elongated spikelets give ita 
very different appearance from the var. cas‘aneus, with which tt 
grew at both localities. 
Eriocaulon bilobatum, n. sp. 
By Tuomas Moronc. 
_Stems numerous, 2-2% inches high, very slender, about 5- 
striate. Leaves acuminate, pellucid, 3-5-nerved, spreading, %- 
% inch long. Sheaths usually bilobed at the apex, loose, some- 
what longer than the leaves. Heads ovoid, 1-1¥% lines high, 
very glabrous and dark-colored. Involucral scales ovate, obtuse, 
entire, fuliginous. Bracts as long as the flowers, elliptical, gla- 
brous. Segments of the perianth 6: of the fertile flowet — 
thread-like, glabrous or slightly woolly, greenish or fuscous 1 
color, loosely cellular in structure, about ¥% line high, the tube 
white; sterile flowers in the apex of the head about the size OF 
the fertile, but the perianth segments broader, lanceolate ™ 
shape, glabrous and fuscous, often reduced to 2 in both the outer 
and inner perianth, Stamens 6, anthers mostly white. Recept@- 
cle smooth. Seeds oval, about py Of an inch in length, the surface 
covered with crested ridges or imperfect recticulations.
