27. J. repexs, Michx. Fl. 1, 191 ; Cephaloxys Jlabellata, 

 Desv.; Chapm. Flor. 496 ; a well marked south-eastern spe- 

 cies, found from Maryland, Canby, to Florida, Alabama, and 

 Louisiana ; it is a true Juncus, as I have shown above, and 

 evidently, notwithstanding its great difference, nearly allied 

 with the last species. Seeds obovate, somewhat pointed, 

 about 0.2 line long, and delicately lineolate.

From the Russian island of Unalaschka, Chamisso, to 

 California, Heenke, Eschscholtz, Douglas, Coulter 808, Bo- 

 lander, and on the Cascade Mountains, 49 deg., Lyall. — A 

 very striking and much controverted plant, as distinct from 

 J. castaneus as it is from J. ensifolius and J. Merte?isianus, 

 with all of which different authors have thrown it together ; 

 the perfectly flat and adverse (*. e. the flat surface facing the 

 stem) leaves, the very broad and scabrous sepals, and the 

 long anthers on short filaments, distinguish it fully from all 

 these. — Eschscholtz's specimens in Hb. Gray are only 1^-3 

 inches, while those of Lyall are 15 inches high ; 6 or 8 inches 

 is their usual size. The leaves are of different lengths, shorter 

 than, or sometimes exceeding, the stem, and are usually late- 

 rally bent so that even the stipular appendages of the sheath 

 are unequal. Heads mostly single, sometimes two or three, 

 h inch in diameter, composed of from 8 to 18 large (3 lines 

 long) flowers ; sepals remarkably broad and rough on the 

 outside, chestnut-brown or (in Coulter's and Lyall's specimens) 

 green, with two lateral brown stripes; this roughness seems 

 to be constant in this species, and in no other have I seen it. 

 Meyer (Rel. ILenk. 1. c.) says of the fruit in Chamisso's speci- 

 men: trigono-p>yriformis perianthio paulo longior trilocu- 

 laris ; seminum testa laxior albicans seel non scobiformis ; 

 none of the specimens before me have ripe fruit, only one, 

 from the Cascade Mountains, shows a half developed capsule 

 with young seeds, and these are undoubtedly tail pointed and
