274 NORTH AMERICAN SPECIES OF JUNCUS. 
Var.? latifolius ; caule erecto (pedali) nudo seu basi unifoliato, folia brevia lineari-lanceolata longe excedente ; 
panicula simplici spatha membranacea rare foliacea longiori; capitulis pauci-(3-5)floris; antheris longe linearibus 
filamento triplo quadruplo longioribus ; seminibus obovatis costato-subreticulatis. 
Californian Sierras on alpine meadows or along rivulets in the Yosemite Valley, alt. 4,000 feet, Hb. norm. 46; 
on the upper Tuolumne, alt. 10,000 feet, and frequent on the eastern slope of the mountains, H. Bolander. — Easily 
recognized by its broad (2-3 lines wide) and short (2—4 rarely 5 inches long) light green leaves, few-flowered heads 
and long anthers, but probably not specifically distinct ; seeds 0.25-0.30 line long, reticulate with faint cross-bars, 
ares: slightly lineolate or almost smooth ; 7 or 8 ribs visible. 
Page 454. J. leptocaulis. The Arkansas specimens have been collected by Dr. Leavenworth; for the Texan 
localities credit is also due to that ardent old gentleman, Dr. Gideon Lincecum, who, in his seventy-ninth year, still 
continues an active botanist, and is now seeking a new field in Mexico.— Mr. Buckley protests against the change of 
his and the restoration of an older manuscript name, and threatens to lay the matter before the public for arbitration, 
in which I wish to assist him, referring only to the remarks on page 454. 
J. marginatus. Var. paucicapitatus ought to follow var. vulgaris ; both are distinguished from the other variety 
by a more slender growth, meagre panicle, and mostly smooth edges of the leaves : in Herb. norm. only gracile 
forms are represented, 33 Pennsylvania, Porter ; 34 West Canada, Bigelow; 35 South Carolina, Ravenel; var. [497] 
biflorus is a stouter plant with broader leaves, rough on the edges and a larger panicle; Hb. norm. 38 Delaware, 
Commons ; 39 S. Carolina, Ravenel. Intermediate forms do not seem to be rare and are found in Hb. norm. 36 and 
37. Characters taken from the relative length of the inner and outer sepals, or from the differences in the shape of 
the capsule, seem to be entirely inconstant. No species bears more abundant seed than this, but in the collections it 
is rarely found fully mature. 
Page 455. J. pelocarpus, as far west as the banks of the St. Peters River, in Minnesota, C. C. Parry. — It seems 
that the plant attains its normal development and bears fruit only in a northern climate, and grows then only 4-7 or 
8 inches high, Massachusetts, Tuckerman in Hb. norm. 45, while the proliferous forms usually become 1 or 2 feet 
high, New Jersey, Smith & Leidy in Hb. norm. 46; the interesting southern var. crassicaudex, Florida, Chapman, Hb. 
norm. 47, is often 2 feet or more in height and bears a very large decompound panicle, 5-9 and even 11 inches 
long. 
A specimen of Michaux’s J. fluitans, from his own herbarium in Paris, bears me fully out in my supposition 
that it is a depauperate water or mud form of this species; its short, rooting stems, about 4 inches long, bear single 
terminal 2-flowered heads, The flower I could examine was not fully open yet, and leaves me in doubt whether it is 
3- or 6-androus. The description of La Harpe is not quite correct in so far as he attributes to the head 2 external 
bracts; while they have 3, as the 2-flowered heads of the regular form have, one under each flower, and a third one 
above the upper flower. Michaux found his plant, as Prof. O. Brunet of Quebec informs me, on the Chicoutimi, 
about 100 miles north of Quebec. 
Page 458. J. articulatus, as far west as the shores of Lake Erie, G. W. Clinton; in Herb. norm. 48 from 
Western New York, Sartwell, and 49 from Massachusetts, Tuckerman.— A form with obtuse 5-flowered green heads 
in a spreading and often almost level-topped panicle, obtuse, mucronate sepals and obtuse short mucronate capsule, 
which I designate as var. obtusatus, has been found by Messrs. Diffenbaugh and Burke on the river near 
Philadelphia; Hb, norm. 50.

Camp Cady, in the southern part of the State of California, Dr. J. G. Cooper, 1861.— A single incomplete speci- 
men, preserved in the botanical collection of the Geological Survey of California, discovered by the zealous naturalist 
whose name it bears, proves this plant to be closely allied to and intermediate between J. acutus and J. maritimus, and 
therefore most probably leaf-bearing. The panicle is 3 inches long and 1 inch wide, green even at full maturity ; 
flowers with the fruit 3 lines long, anthers 13 lines in length ; seeds with white rhaphe and broad white appendages 
line long; marked with irregular longitudinal reticulation. J. acutus (also found at San Diego by Dr. Cooper) has 
smaller flowers of different shape, and a deep brown almost globose capsule, and smaller differently marked seeds ; J-
