NORTH AMERICAN SPECIES OF JUNCUS. 275 
maritimus, not yet found in North America, has all the parts much smaller, an ovate mucronate capsule, smaller seeds 
with short appendages. 
. acuminatus, var. diffusissimus, exactly corresponding with the Texan plant, found by the late Dr. Clapp near 
New Albany, Indiana, is preserved in Hb. Torrey. 
The account of Juncus in Gray’s Manual, 5 ed., 1868, 537-544 and the Juncee of Watson’s 
Botany of Wheeler's Expedition, 1878, 272-274, are omitted from the reprint, as they add nothing to 
this paper. — Eps.

Juncus MarItTIMus, Lam. In your list of Junci of the New York Flora, No. 6, p. 24, you mention J. Remeri- 
anus from Coney Island. Several years ago Professor Chas. H. Peck of Albany sent me the true J. maritimus, Lam., 
as collected on that same island, in Sept., 1868, a plant which I had not before seen from any American locality. 
Have you compared your specimens from Coney Island well? Are they really J. Remerianus, and do both species 
grow there? If not, what then is the limit of J. Ramerianus? Besides rit characters of the flowers and 
fruit, they can be distinguished at a distance by their habit and color. J. maritimus has a green, contracted, and 
J. Remerianus a spreading brown panicle, and blooms, I believe, much earlier [1873. IV. 40].

JUNCUS RUGULOSUS, n. sp. Pale green, transversely rugose and rough, stems 2-4 feet high from a stout running 
rhizoma, very weak, leafy ; leaves septate ; panicle lax, decompound, 6-8 inches long and wide; heads with hyaline 
bracts, 3-5-8-flowered ; sepals linear-lanceolate very acute, nearly equal, the outer carinate-one-nerved, the inner 3- 
nerved ; stamens 6, much shorter than sepals, linear anthers shorter than filaments ; capsule exceeding the calyx, 
lanceolate, acute, 3-angled, 1-celled ; seeds acute at both ends but not caudate, reticulate. 
n a running streamlet at the foot of the San Bernardino Mountains, discovered by W. G. Wright, and seen there 
by me also in November. — With J. asper the only species of our flora with rough epidermis. It may be compa 
with loose panicled ic. of J. acuminatus var. debilis, but is readily distinguished by its roughness and its 6 stamens, 
and then, no forms of J. acuminatus occur west of the great plains [1881, VI. 224-5]. 
JUNCUS CANALICULATUS, n. sp. A coarse plant of the section Graminet, 3 feet or more high, from a cespitose 
rootstock, with stout terete stems and numerous concave or channelled leaves, 2 or 3 of them with auricled sheaths on 
the stem ; heads 3 to 8-flowered, on slender branches in a decompound rather contracted panicle ; flowers light green- 
ish-red, over 2 lines long ; sepals of nearly equal length with membranaceous margins, inner acute, outer ones acumi- 
nate ; stamens 6, two-thirds the length of the sepals, long linear red-brown anthers longer eae — filaments ; ovary 
attenuated into a slender style bearing very long exsert stigmas, 1-celled ; fruit and ood unkno 
n Bernardino Mountains, at 4,000 feet alt., S. B. and W. F. Parish. Abundantly distinguished from the 
allied J. marginatus, with which it has in common the brown-red anthers, otherwise rare in the genus, by the stouter 
ie the long coarse deeply channelled leaves, larger flowers, acute sepals, acuminate ovary, long style and stigmas 
1882, VII. 6].
