With some hesitation I refer the sted egos baer: 
of which I have numerous and well preserved specimens be- 
fore me, to J. Matinataive of the N persephriee' aa ah au- 
thentic specimens of which, at my disposal, are rather incom- 
plete; but they are distinct enough to prove Meyer wrong in 
referring the Sitcha plant to his J. falcatus (Ledeb. FI. Ross. 
4, 228). Bongard, to be sure, describes nm leaves as flat, but 
they are not adverse like those of J. fulcatus, but averse like 
Pie of J. xiphioides, and, Genaes are slightly but distinctly 
notted. 
Stems 7-14 inches high, compressed, but not ancipitous 
except in var. 8, “ weak and flaccid” (Hall), grooved below, 
smooth upwards; ‘erent as in all its allies, of very different 
width, usually 3-1 or rarely 13, but in 3 14-23 lines wide; 
heads 43-6 lines in diameter; flowers very distinctly pedi- 
silted, 1 to (commonly) 2 lines long; inner sepals, as in this 
whole section, quite variable, obtuse to acute and even acumin- 
ate, usually shorter, but in some flowers of the Sitcha dev

0.50 line long; 7-9 and in some Rocky Mountain specimens 
(Drummond, Hall) 9-12 ribs are visible on the side; the sur- 
face is regularly reticulated with more or less distinct cross-

r. 8, with its tall stem, long and broad leaves, and a pan- 
sole of 3 inches in length, looks ¢ quite distinct from the ordin- 
orm, but I cannot find any more essential differences.
