950 NORTH AMERICAN SPECIES OF JUNCUS. 
Cascade Mountains, Lyall; and to Unalaschka; the variety on Mount Shasta, Calif., at an altitude of 8,400 
feet, Brewer. — The soft, compressible stems are 8-17 inches high, and always, as far as I have seen, leafless; [446] 
and when Meyer (FI. Ross. 1. c.) says that they occasionally bear leaves, he had probably one of the allied leaf- 
bearing species before him, which are at first glance so much like our plant that they have been almost constantly 
confounded with it. The spathe is 5-1} inches long and usually exceeds the flowers ; in the variety it measures only 
2 or 3 lines and is shorter than the flowers, of whieh the primary one is sessile and the accessory one peduncled, just 
as we see it in J. biglumis. Flowers 3 lines or more long; sepals green on the back, brown on the sides, pale and 
membranaceous on the margins ; outer ones with 5-7 nerves ; stamens less than one-half, often only one-third as long 
as the sepals ; capsule deep chestnut-brown and shining; seeds 0.3 line, or including the tails, about 1 line long; 
appendages as long as, or longer than, the body of the seed, which is delicately striate, with 10 or 12 ribs visible (on 
one side), and distinctly cross-lined ; it is one of the very few species in which we find the appendages as long as 
or longer than the seed itself. 
14. J. Hawi, n. sp.: cespitosus ; caulibus (spithameis pedalibus) teretibus filiformibus folia teretia setacea 
longe superantibus ; spatha paniculam subsimplicem paucifloram coarctatam vix sen parum superante ; sepalis 
lanceolatis acutis, exterioribus paulo longioribus stamina 6 bis superantibus; antheris linearibus filamento paulo 
brevioribus; stigmatibus subsessilibus ovarium ovatum equantibus inclusis; capsula ovata angulata retusa triloculari 
vix exserta ; seminibus oblongo- aaa striato-reticulatis longe caudatis. —J. arcticus, var. gracilis? Gray in Pl.

Near Lake Ranch, ei ‘Hall & Harbour, Rocky Mountain Flora, No, 562; for the former of whom, Mr. E. 
Hall, of Athens, Menard county, Ill., who discovered this and many other plants in that region, it is named, It 
seems to be a rare plant, as neither Dr. Parry nor any one else, so far as I know, has obtained it. — Stems very slender, 
6-12 inches high; leaves from 2-5 inches long, grooved just above the vaginal part, terete upwards ; spathe as long as, 
or a little longer than, the compact inflorescence, which consists of 2-5 flowers about 2 lines long; capsule deep brown, 
as long as, or longer than, the acute but not subulate-pointed, chestnut-brown, white-margined sepals; seeds 0.5-0.6 
line long, the body of the seed being about 0.3 line long, and the appendages half as long as the body, or often shorter ; 
I notice on one side of the seed about 10 delicate ribs. 
6: J. PAaRRYI, n. sp.: czspitosus; caulibus setaceis humilibus (digitalibus spithameis) folia sulcata 
sursum .teretia superantibus; spatha paniculam simplicissimam (1-3-floram) superante ; sepalis lanceolato- [447] 
eae exterioribus longioribus aristatis stamina 6 ter superantibus; antheris linearibus filamento bis terve 
longioribus ; stigmatibus ovarium lineari-prismaticum in stylum attenuatum vix equantibus inclusis ; capsula pris- 
matica acutata exserta triloculari; seminibus oblongis tenuiter Soaae longe caudatis. —J. arcticus, var. 
gracilis ? Gray in Pl. Parry, p. 34, and in Pl. Hall. & Harb. 1. ¢., ex part 
On the western and northwestern mountains; Dr. C. C. Parry, the “indefatigable explorer of those mountain 
_ regions, who has been so often mentioned in the pages of these an aan and ee whom I have named this in- 
teresting little plant, discovered it in Colorado in 1861 (coll. No. 360); Messrs. Hall & Harbour found it in the same 
region (No. Ree Dr. Hillebrand in the Sierra Nevada, and Dr. pr in the Cascade Mountains: it is generally, as it 
seems, associated with J. Drummondii.— Stems very thin and wiry, 4-8 inches high, leaves one-half to two-thirds as 
long, deeply grooved for over half their length, terete upwards; spathe usually overtopping the flowers, often 1 inch 
or more long; flowers mostly two, very rarely three in number, 2}-3$ lines long, larger than those of the last two 
species, and distinguished by their bristle-pointed exterior sepals, which are greenish, with brown sides and white 
margin, and strongly nerved. After maturity the placente of the slender and very acute brown capsule become 
detached from the valves and persist in the centre. The whole seed is about 1 line, and the body alone about 0.4 line 
long ; longitudinal ribs 10-12 on one side, cross-lines very faint. A Californian specimen before me has somewhat 
shorter capsules and smaller and thicker seeds, but shows no other difference. 
16. J. TrrFIpvs, Linn., apparently a rare plant in North America ; thus far found only on the highest moun- 
tains in New York, New Hampshire, and Maine, and in Newfoundland and Greenland.— American specimens do not 
differ from those of Europe. The seeds are few and large, irregularly compressed, very faintly striate, with very short 
appendages ; 0.7-0.8., or even as much as 1.1 lines long, and 0.3 line or more in diameter. 
17. J. Bigtumis, Linn.: the only American localities known to me are those given by Hooker (Fl. Bor. Am. 
2, 192) —“ Arctic sea coast and islands, Rocky Mountains north of Smoking River, and Behring’s Straits.” A speci- 
men from the Arctic sea coast, which I had the opportunity of examining, does not differ in any respect from the 
Norway and Lapland plant. The body of the seed is ovate-oblong, 0.34-0.42 line, and with the appendages 
0.66-0.72 line, long; these are equal to, or shorter than, the diameter of the seed. In a Scotch specimen I [448] 
have seen a regularly tetramerous flower, with 8 sepals, 8 stamens, and a 4—valved capsule. The leaves, which 
botanists do not seem to agree upon, appear to me fistulous, on the lower half so deeply grooved as almost to present 
two cavities, and upwards nearly terete or slightly flattened. Its alliance with J. Parry: is indeed very close.
