ENGELMANN — NORTH AM. SPECIES OF JUNCUS. 453 



already 0.0 line long; Dr. Hooker (Bot. Antarct. Voy. Fl. 

 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. 



29. J. longistylis, Torrey in Bot. Mex. Bound, p. 223: 

 caulibus (pedalibus bipedalibus) crespitosis stoloniferis tereti- 

 usculis sursum saepius (sub lente) scabriusculis foliatis ; folds 

 planis gramineis; capitulis paucis in paniculam contractam 

 aggregatis seu raro singulis; floribus (majoribus viridulis 

 fusco-striatis) lsevibus pedicellatis ; sepalis aaqualibus ovato- 

 lanceolatis acutatis seu cuspidatis stamina 6 duplo superanti- 

 bus; antheris filamento sub-duplo longioribus; ovario stami- 

 na et stylum requante, stigmatibus exsertis ; capsula ovata 

 obtusa mucronata seu rostrata castanea nitida triloculari 

 calycem aequante seu paulo superante ; seminibus oblanceo- 

 latis seu obovatis apiculatis costato-reticulatis. — J. Menziesii, 

 Gray in PI. Parry, p. 34, and PL Hall & Harb. p. 77, "the 

 var. Califomicus, Hook & Am., probably an unpublished 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 

 Saskatchewan, Pourgeau, and towards Oregon, Lyall. — 

 Stems cespitose, or, probably in richer soil, stoloniferous, 1-2 

 feet high; panicle usually Xh-lh or 3 inches long, consisting 

 of 5-9 heads ; heads 3-8 or 12-rlowered, sometimes fewer or 

 single, and then 12-15-flowered ; flowers 2^-3 lines long; 



* The Tasmanian J. falcatus, Hook. f. 1. c, 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 area? of which 

 are jierpcndicularly lineolate ; it might be distinguished by the name of J. 

 Tasmanicus. 



f 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/, 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.
