Carex Parryana var. Statoni Jones n. var. Spikelets 3-4, all sessile, con- 

 gested into an ovate to oblong head, rusty, the terminal one 1.5-2 cm. long, 

 the rest somewhat smaller to a third as long, all oblong, densely flowered, 3-6 

 mm. wide, appressed, the terminal one thickest. All wholly pistillate or 

 with a few staminate at tip. Perigynia trigonous, rhomboidal obovate, the 

 base with a substi^tate spongy thickening, the tip triangularly contracted 

 into narrow tip or beak not much longer than high, which is oblique, hyaline 

 and notched, strongly 3-nerved with two on the sides and one on the inner 

 face and all rounded and thickened, with 6-8 fine nerves on the outer face, 

 granulated, 2 mm. long and 1 mm. wide and about half as thick, rusty col- 

 ored. Scales ovate, acute, a little longer than the perigynia, rusty. Stigmas 

 mostly two though frequently 3-stigma flowers are intermixed. Bracts all 

 brown and scale-like, sheathing. Stems sharply-triangular, about 6 dm. high, 

 erect but slender, leafy only near the base, stoloniferous, granulated but 

 seeming smooth. Leaves 2-3 mm. wide, revolute, acuminate, about a third 

 as long as the stems, papillose, with fibrillose sheaths, light-green. Growing 

 in dry meadows. Deer Lodge Valley, Montana. The type collected at Ryan's 

 ranch, Aug. 3rd, 1905. Dedicated to 'W. C. Staton of Anaconda. I also refer 

 to this material got in the same valley in July, wliich is only 2 dm. high, 

 with smaller spikes and scales, hardly as long as the perigynia, though hav- 

 ing the same rusty color, with the light center and very narrow wihte edges 

 of the type and the perigynia fully 2-3 times as thick as wide and like the type 

 filled by the seed. This would seem to come near to C. Idahoa Bailey. 



Carex Goodenovii var. doiia Jones n. var. Spikelets all on filiform pe- 

 duncles, 2-10 mm. long, clustered in a deltoid head, 3-5, 5-15 mm. long and 

 about 3 mm. wide, densely flowered, broadly linear, nearly black and with 

 green perigynia, the terminal one with a few staminate flowers at the base 

 and then clavate, or rarely at both tip and base. Perigynia broadly ovate, 

 granulated, nerveless except the two lateral ones at the tip, plano-convex, 

 2 mm. long, green or flecked with purple above, sessile and with a spongy 

 ring at base, filled by the seed, with a minute cylindrical beak not longer; 

 than high, appressed. Scales oblong, rounded and obtuse, black with light 

 center, nearly as long as the perigynia. Bracts setaceous, green, with black 

 auricles, the lower often 1 dm. long, sheathless. Stems filiform, 1.5-2 dm. 

 high, nodding, obtusely angled, papillose as well as the leaves, densely caes- 

 pitose, leafless except at very base. Leaves dark-green, 2-3 mm. wide, in- 

 volute, shortly acuminate, about half as long as the stems, witli hyaline non- 

 fibrillose sheaths. Growing in dense mats above timber line at Sperry Gla- 

 cier, Montana, in moist meadows. This evidently belongs in the C. Good- 

 enovii group with two stigmas, and is nearest C. Goodenovii var. limnophila 

 (Holm, as vulgaris var., Proc. Am. Acad. 17 307), but differs from that in the 

 spongy base of the perigynia, nerveless, not sessile spikelets and narrower. 

 It also differs fro mthe var. lipocarpa (Holm. Proc. Am. Acad. 17 308 as vul- 

 garis var.) in the not stipitate and nerveless perigynia, granulated, clustered 

 and short spikelets, etc. It differs still more from the var. hydrophila (Holm. 

 1. c. as vulgaris var.) in the caespitose stems, granulated and not stipitate 

 perigynia.
