452 TRANS. OF THE ACAD. OF SCIENCE. 
27. J. repens, Michx. Fl. 1, 191; Cephaloxys flabellata, 
Desv.; Chapm. Flor. 496; a well marked south-eastern spe- 
cies, found from Maryland, Candy, to Florida, Alabama, and 
Louisiana; it is atrue 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, Hanke, “schscholtz, 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. Mertensianus, 
with all of which different authors have thrown it together ; 
the perfectly flat and adverse (7. 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 13-3 
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, 
4 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. Henk. 1. c.) says of the fruit in Chamisso’s speci- 
men: trigono-pyriformis perianthio paulo longior trilocu- 
laris; seminum testa laxior albicans sed 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
