erect alternate-flowered spikes and short perigynia distinguish it 
from the common var. Rudgei. 
Carex granularis, Muhl., var. REcTA, Dewey, Wood’s Cl. Book, 
1860, 763. 
A very tall slender plant, with narrow erect leaves, narrow 
spikes, of which the lower are on very long and slender stalks; 
pergynium less inflated than in the type and straighter. Glaucous. 
Dewey records it from Southern Illinois (Vasey) and Louisiana 
(Hale). I have it from Virginia, Southern Illinois, the mountains 
of Georgia, and Mississippi. It is a well-marked form. No one 
seems to have taken up the variety except Paine, in his Catalogue 
of Oneida plants (1865); but Paine must have misunderstood it, 
for I do not know that it occurs in the North. 
CAREX GRACILLIMA  AESTIVALIS ? 
Mr. C. L. Shear sends me from eastern New York, good 
specimens of a most distinct and novel carex. He first found 
the plant last year (1892), in a moist meadow at Alcove, Albany 
county. A single clump only was observed, and it grew with 
C. gracillina. In 1893 Mr. Shear found it again at two places in 
Greene county—between Windham and Ashland, and at Hunter 
—Sgrowing in clumps in mountain pastures. The plant differs 
Visibly from C. gracillima in its much stricter habit, narrow leaves, 
nearly erect spikes, and by the distinctly beaked and toothed 
Perigynium. Its association with C. gracillima, and the fact that 
it is uniformly wanting in good achenia, indicate that the plant is 
a hybrid. I am unable to determine what its other parent may 
be, but the fact that the perigynia are attenuated at the top, that 
the leaves are narrowed, the lower sheaths slightly pubescent, and 
the habit essentially erect, strongly suggest C. estivalis, and this 
Species occurs on the mountains of western Massachusetts and in 
“astern New York. I suspect that further search will discover 
C. @stivalis in the mountain pastures of Albany and Greene 
Counties. It is by no means necessary to the diagnosis of a 
hybrid that both parents be found in its vicinity. One parent, or 
_ ven both of them, may long since have died out and the hybrid 
_ May have persisted; yet the hybrid is usually associated with its 
_ Pistillate parent. I have found undoubted hybrids of Rubus in
