ENGELMANN—NORTH AM. SPECIES OF JUNCUS. 453 
already 0.6 line long; Dr. Hooker (Bot. Antarct. Voy. FI. 
Tasm. 2, 64) speaks of the seed of this species as “ linear- 
oblong, striate, with the testa produced beyond either end,” 
and as the Tasmanian plant* has very different seeds, his 
remark must refer to the Californian species. 
Hooker & Arnott, Bot. Beechey, p. 402, distinguish from 
the original J Menziesii, with obtuse sepals, the variety 
Californicus, with acuminate ones; I have found, in all the 
specimens, examined by me, the outer sepals acuminate and 
the inner ones obtuse, with or without a mucro; but in some, 
as stated before, the outer ones are much shorter than, in 
others as long as, the inner ones.

caulibus (pedalibus bipedalibus) czspitosis stoloniferis tereti- 
usculis sursum szpius (sub lente) scabriusculis foliatis; follis 
planis gramineis; capitulis paucis in paniculam contractam 
ageregatis seu raro singulis; floribus (majoribus viridulis 
fusco-striatis) levibus pedicellatis; sepalis equalibus ovato- 
lanceolatis acutatis seu cuspidatis stamina 6 duplo superanti- 
bus; antheris filamento sub-duplo longioribus; ovario stami- 
na et stylum equante, stigmatibus exsertis; capsula ovata 
obtusa mucronata seu rostrata castanea nitida triloculari 
calycem equante seu paulo superante; seminibus oblanceo- 
latis seu obovatis apiculatis costato-reticulatis—J. Menziesit, 
Gray in Pl. Parry, p. 34, and Pl. Hall & Harb. p. 77, “the 
var. Californicus, Hook & Arn., probably an unpublished 
species.” 
Rocky Mountains from New Mexico, Wright 1924, Fendler 
857, to Fort Whipple, Arizona, Coues & Palmer 48, and 
northward to Colorado, Parry 631, Hall & Harb. 566, to the 
Saskatchawan, Bourgeau, and towards Oregon, Lyall. — 
Stems cespitose, or, probably in richer soil, stoloniferous, 1-2 
feet high; panicle usually 13-23 or 3 inches long, consisting 
of 5-9 heads; heads 3-8 or 12-flowered, sometimes fewer or 
single, and then 12-15-flowered; flowers 24-3 lines long; 
* The Tasmanian J. falcatus, Hook. f. 1. ¢., of which I find a good 
specimen with ripe fruit, collected by Gunn, in Hb. Gray, is certainly 
very similar, but seems to be distinguished by smaller but also scabrous 
flowers ; ovate, retuse capsules of the length of the equal, acutish sepals ; 
and obovate, obtuse, abruptly apiculate reticulate seeds, the areee of which 
are perpendicularly lineolate ; it might be distinguished by the name of se 
Tasmanicus. 
+ While this sheet was in the hands of the printer I received a most 
interesting collection of Arizona Plants, made last year by Drs. Elliott 
Coues, and Edward Palmer, in which I found good specimens of this 
species, and also some of J. compressus, unfortunately again without fruit ; 
the leaves of this last, however, are finely developed, thus adding another 
proof for the opinion, that it is really a regularly leaf-bearing species.
