bracts small and scarious. Stamens always 6. Capsule 1-celled, 
with 3 parietal placente and 1-3 erect seeds. | 
J. pilosum Kuntze Rey. Gen. ii, 725. Tufted, often somewhat stolon- 
iferous: stems erect, 2-4-leaved, 6-12 inches high: radical leaves 2-6 inches 
long, 2-4 lines wide, slightly pubescent, acuminate into a blunt almost 
gland-like point: cauline leaves similar but successively shorter: inflores- 
cence an umbel-like cluster, the filiform pedicels usually nearly equal, 
1-2-flowered: perianth 1-114 lines long, its segments triangular-ovate, 
acuminate, brown with hyaline margins, almost twice as long as the 
toothed bractlets: capsule about 14 longer than the perianth, its valves 
ovate-lanceolate: seeds about 1 line long, with a conspicuous hooked ca- 
runcle at the summit. Oregon to Alaska and in the Alleghany Mountains; 
also in Europe and Asia. 
J. spadiceum Kuntze |. c. 724. Glabrous or slightly villous: stems 
6-18 inches high: leaves 4-6 inches long, 3-5 lines wide, acute or shortly 
acuminate: inflorescence lax, and drooping, much exceeding the usually 
small involucral bracts: perianth straw-color or tinged with brown, the 
segments lanceolate, acuminate, about 1 line long, slightly shorter than the 
acute apiculate capsule: seeds oblong, brownish, not appendaged. In the 
mountains, California to the Arctic regions and the northern Atlantic 
States: also in Europe. 
J. parviflorum Coville Cont. Nat. Herb. iv, 209. Stems slender, 
tufted, 1-2 feet high: leaves narrowly lanceolate, 3-6 inches long: 3-6 lines 
wide: inflorescence a loose decompound panicle, commonly 3-4 inches high, 
its lowest bract foliaceous, seldom more than 44 the length of the panicle: 
flowers borne singly or 2-3 together on the branches of the panicle, on 
slender pedicels: bractlets ovate: Feedage 34-114 line long, its segments 
ovate, acuminate, slightly exceeded by the green to brown ovoid capsule: 
feeds narrowly oblong, attached to the placente by a slender fibre. In 
sorests, Alaska to California and the northern Atlantic States. 
Var. melanocarpum Sheldon Bull. Geol. Surv, Minn. ix, 63. Stems 
stouter and shorter: leaves more numerous, and somewhat broader: inflor- 
escence more dense: bracts all scarious: pedicels 3-6 lines long: perianth 
and capsule dark brown. On the highest parts of the Cascade Mountains. 
Var. subcongestum Sheldon 1. c. Often tufted: leaves narrower: 
inflorescence more narrowly paniculate: pedicels only a line or two long, 
the flowers thus appearing in small heads. In the high mountains, Alaska 
to California. 
J. spicatum Kuntze 1. c. 725. Closely tufted, without rootstocks : 
stems erect, 4-16 inches high, distantly 1-3 leaved tapering to a filiform 
summit: leaves 2-3 lines wide, often involute, tapering to a sharp apex: 
inflorescence a nodding spike-like often interrupted panicle, commonly 
9-15 lines long, usually exceeded by the lowest leaf-like bract, ovate-lan- 
ceolate, acuminate, equalling the perianth : segments of the perianth brown 
with hyaline margins, 1-14¢ lines long, !anceolate, aristate-acuminate: 
Se broadly ovoid, about 24 as long as the perianth: seeds narrow and 
obliquely obovoid. Alaska to California and across the continent. 
J. comosum Sheldon |. c. 64. Stems slender, 6-15 inches high, leafy, 
leaves 3-4 inches long, 1-3 lines wide, the foliaceous bract usually exceed- 
ing the narrow panicle: peduncles 2-12, unequal, the longer 1-3 inches long 
_8pikes simple, usually oblong, loosely-flowered: perianth pale or somewhat 
tinged with brown, about 144 lines long, its segments narrowly acuminates 
equalling the obtuse capsule: anthers small, as long as the filaments: seed, 
dark brown with a white caruncle, appendage sometimes half as long as 
the seed. Alaska to California and the Rocky Mountains.
