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 liueolate 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 ver)' 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.
