JUNCUS 
Var. congestum Sheldon |. c. Spikes several, sessile and closo, 
forming a somewhat pyramidal head: bracts white and conspicuous: peri- 
anth brown, 14 lines long. Near the coast, Oregon to California. 
Var. macranthum Parish. Perianth 2-3 lines long, much exceeding 
the broad obtuse capsule: anthers equalling or twice longer than the fila- 
ments: seeds longer, the appendage always short. Alaska to California. 
Var. subsessile Watson Bot. Cal. ii, 203, under Luzula. Spikes 
solitary or few, nearly sessile, loose: perianth-segments lax and scarious. 
Oregon to California. 
J. campestre Kuntze |. c. 724. More or less villous with long white 
hairs: stems densely tufted, erect, 4-10 inches high, 2—4-leaved : leaves 2-5 
inches long, 1-4 lines wide, tapering at the apex to a blunt almost gland- 
like point: branches of the panicle. unequal, straight, each bearing an 
oblong or short-cylindric dense spike: the lowest bract leaf-like, often 
exceeding the panicle: floral bracts white, ovate, acuminate, about equal- 
ling the flowers: segments of the perianth lanceolate-ovate, acuminate, 
brown with white margins, 1-11 lines long: capsule obovoid ; seeds oblong, 
with a thick white appendage at base. In the mountains, Alaska to 
California and the Eastern States. 
J. divaricatum Coville 1. c. Stems 4-7 inches high: cyme broadly 
diffuse, with divaricately spreading branches and pedicels: perianth tinged 
with brown: seed light-colored, with a small appendage at base. In the 
Cascade and Sierra Nevada Mountains, southern Oregon to California. 
2 JUNCUS L. Sp. 325. 
Glabrous perennial or annual plants, growing in wet or moist 
places, with simple terete leafy or leafless stems, terete channel- 
led or flat, sometimes equitant, often knotted leaves and small 
flowers in clusters, cymes, panicles or heads or solitary. Stamens 
6, or sometimes 3 by supression of the inner ones. Capsule glo- 
bose to pyramidal, many-seeded, 3-valved, 3-celled with central 
placentz, or 1-celled with parietal placentz. Seeds usually dis- 
tinctly reticulated or ribbed, often tailed. 
* Stems leafless and scape-like, from matted rootstocks, sheathed 
at base: the inner sheaths sometimes bearing terete leaves: flowers in 
sessile apparently lateral panicles. f 
+ Scapes slender: sheaths mostly leafless: spathes usually very 
much exceeding the panicle: stamens usually 6. 
+« Flowers in compound panicles, two lines long or more: capsule 
oblong-ovate. ) 
J. Lescurii Bolander Proc. Calif. Acad. ii, 179?. Stems stout, 1-3 
feet high, from a stout creeping rhizome: sheaths short, black, obtuse: 
spathe 6-15 inches long very acutely pointed; flowers in a dense somewhat 
secund many-flowered panicle: bracts ovate, acuminate: perianth-segments 
216-3 lines long, lanceolate, acuminate: greenish-white with intermarginal 
brown stripes: anthers much longer than the filaments: capsule brown, 
triquetrous, sharply angled, acute, shorter than the perianth: seeds ovate, 
obtuse, scarcely apiculate. In shifting sands along the coast of Oregon: 
perhaps distinct from J. Lescurii as that species is said to grow in ‘‘Salt- 
marshes and saline localities’’. 
J. Balticus Willd. Berlin Mag. iii, 298. Stems erect, 8-36 inches 
high, arising at intervals from stout creeping rootstocks: sheaths green or 
tinged with dark brown: spathe slender, 4-6 inches long: panicle commonly
