 brown, not reticulated. Prodr. 1. c. 700, founded on a small and slender 4-seedecl form.

= = Leaves mostly narrower, 3 7-ribbed, entire or barely denticulate, tapering at base into 

 more or less of a petiole : ovules and seeds never over 2 in each cell. 



a. Not maritime nor montane, thin-leaved: ovules and seeds solitary in each cell. 



P. sparsiflora, Michx. Leaves oblong-lanceolate (4 to 9 inches long), villous-pubescent 

 or glabrous : scape with the filiform sparsely-flowered spike 8 to 20 inches long : bracts 

 ovate, shorter than the oval rather rigid coriaceous sepals : capsule oblong, umbilicate, fully 

 twice the length of the calyx. Fl. i. 94 ; Decaisne, 1. c. 721 . P. Virnmira, Walt. Car. 85 1 

 P. interrupta, Poir. Diet. v. 375. P. Caroliniana, Pursh, Fl. i. 98, not Walt. Low pine 

 barrens, S. Carolina to Florida. 



b. Montane, thin-leaved : ovules and mostly seeds a pair in each cell. 



P. Tweedyi. A span or two high from a slender root or rootstock, destitute of wool at the 

 crown : leaves membranaceous, lauceolate-spatulate, entire or obsoletely denticulate, ob- 

 scurely 3-5-uervecl, 1 to 3 inches long, attenuate into a shorter margined petiole : spike 

 slender but densely flowered, an inch or more long : bracts and sepals short (only a line 

 long), pale with greenish midrib, little over half the length of the oblong capsule. N. W. 

 Wyoming, on grassy slopes of the East Fork of the Yellowstone River, Frank Tweedy, Aug., 

 1885, in fruit. 



c. Maritime or in saline soil: leaves thickish and somewhat fleshy: ovules a pair in each cell. 



P. eriopoda, Torr. Usually a mass of yellowish wool at the crown : leaves oblanceolate 

 to oval-obovate, 3 to 6 inches long and with short or stout petiole, mostly glabrous : scapes 

 pubescent or glabrate, and with the dense or sparsely-flowered spike a span to a foot high ; 

 bracts broadly ovate or roundish, convex, scarious-margined, sometimes pubesceut-ciliate : 

 sepals roundish-obovate, scarious except the fuscous or greenish midrib : corolla-lobes 

 broadly oval or ovate: capsule (2 lines long) ovoid, slightly exceeding the calyx. Ann.

 not Wall. P. (/Ifibra, Nutt. Gen. i. 100 ? but no specimen extant. P. lanceohitu, var. y & $ 

 in part, Hook. Fl. ii. 123. P. virescens, Barneoud, Monogr. 33; Decaisne in DC. 1. c. 721. 

 P. Richardsonii, Decaisne, 1. c. 698. Moist and saline soil, Colorado, N. California, and 

 north to Mackenzie River. Also on the Lower St. Lawrence and the Gulf (Prinnle, Allen, 

 Maconn), where a large form emulating P. Corniiti is probably P. cncu/lata, Pursh. 



P. macrocarpa, Cham. & Sdll. Leaves lanceolate, acute, 4 to 15 inches long, 4 to 12 

 lines wide, gradually tapering into long margined petioles : scapes equalling or surpassing 

 the leaves, bearing an oblong dense spike (in fruit 2 inches long) ; the rhachis, &c., tomen- 

 tose or pubescent : bracts round-ovate or oval, fleshy-herbaceous and scarious-margined : 

 sepals similar: corolla-lobes oval: mature capsule ovoid-oblong (3 or 4 Hues long), sepa- 

 rating from the base and then fissile : seeds narrowly oblong. Linn. i. 106 ; Bong. Veg. 

 Sitk. 42. P. macrocarpa & P. tonr/i folia, Decaisne, 1. c. Coast of Washington Terr, to 

 Alaska and the farthest Aleutian Islands. 



i i Corolla with tube externally pubescent: capsule 2-4-seeded (in ours seldom incompletely 



3-4-celled): seeds not excavated nor concave on the face: leaves linear or filiform, fleshy; 

 rilis usually indistinct: commonly some wool developed from bases of leaves. (Maritime 

 species.) 



P. maritima, L. Root perennial : leaves mostly obtuse : spike dense, oblong or cylin- 

 drical : bracts mostly rotund and shorter than the calyx : sepals oval, more or less acutely
