ENGELMANN—NORTH AM. SPECIES OF JUNCUS. 445 
most of the later writers make mention of the leaves, while E. 
Meyer (Syn. June. 1822, p. 18) already describes them, and 
Gray and Chapman are fully acquainted with them. Though 
its author credits the species to Pennsylvania, it is not now 
known to grow there; in all the herbaria examined by me I 
have seen no specimens found north of North Carolina, 
whence it extends as a common species to Florida and Loui¬ 
siana.—It is well characterized by its terete leaves; a very 
long spathe; a compact or, sometimes, spreading, few-flow¬ 
ered panicle; smooth and shining sepals; a globose, scarcely 
angled, but conspicuously rostrate capsule, the dissepiments 
of which separate from the valves; and by the sub-globose, 
obtuse, coarsely lineolate or almost transversely reticulate 
seeds, with short appendages and distinct raphe, and sel¬ 
dom over 0.3 line long. 
12. J. arcticus, Willd. The only American specimens I 
have seen were brought from Greenland by Dr. Kane; they 
differ in no respect from the European plant. The seeds are 
0.4 line long, obovate, oblique, obtuse, with very short append¬ 
ages and distinct raphe; 12-16 ribs are visible on one side, 
with very faint cross lines. 
Of*the plant which is found on the Russian islands Kodiak 
and Sitcha, on the north-west coast of America, I have seen 
too few and too incomplete specimens to form a definite 
opinion. It seems to me to constitute a sub-species of J. 
arcticus , which might be designated as Sitchensis , and which 
can be distinguished by the much elongated spathe, the 
larger flowers, nearly equal sepals, turbinate pyriform capsules, 
with very few and apparently smaller seeds.
