 middle: ovules 6 to 10: seeds 4 to 9, oval-oblong (about a line long), opaque and dull 

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

 4. — P. major, Ell. Sk. i. 201 ; Torr. Fl. 183, & Fl. N. Y. ii. 14 ; Darlingt. Fl. Cest. ed. 2, 110.

 no trace of it is found in the Old World. 



= = Leaves mostly narrower, fewer-ribbed, entire or obscurely denticulate, tapering at base into 

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



P, sparsiflora, Michx. Leaves oblong-lanceolate, acute, thinnish (4 to 7 inches long), 

 tapering into a slender petiole, villous-pubescent or glabrous, 3-5-herved : scape with the 

 filiform sparsely-flowered spike 8 to 20 inches long : bracts ovate, shorter than the oval 

 rather rigid coriaceous sepals : corolla-lobes oblong-ovate, acute : capsule oblong, umbili- 

 cate, fully twice the length of the calyx : seeds (also ovules) solitary in each cell, oblong, 

 narrowly shallow-concave on the face. — Fl. i. 94; Decaisne, 1. c. 721. P. Virginica, Walt.

 to oval-obovate, fleshy-coriaceous, 3-7-nerved, 3 to 5 inches long and with short or stout 

 petiole, mostly glabrous : scapes pubescent or glabrate, and with the cylindrical and dense 

 or sometimes sparsely-flowered spike a span to a foot high ; bracts broadly ovate or round- 

 ish, convex, scarious-margined, sometimes pubescent-ciliate : sepals roundish-obovate, sca- 

 rious except the fuscous or greenish midrib : corolla-lobes broadly oval or ovate : capsule 

 ovoid, slightly exceeding the calyx : ovules a pair in each cell : seeds as many or fewer, 

 oval, flat on the face. — Ann. Lye. N. Y. ii. 237 ; Watson, Bot. King, 212. P. attenuata,

P. macrocarpa, Cham, & Schl. Leaves thinner, lanceolate, acute, &-7-nerved, 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., tomentose or pubescent : bracts round-ovate or oval, fleshy-herbaceous and 

 scarious-margined : sepals similar but almost wholly scarious : corolla-lobes oval : mature 

 capsule ovoid-oblong (3 or 4 lines long), separating from the base and then fissile, 2-ovuled, 

 1-2-seeded : seeds narrowly oblong, flat or slightly concave on the face. — Linn. i. 106 ; 

 Bong. Veg. Sitk. 42. P. macrocarpa & P. longifolia, Decaisne, 1. c. — Coast of Washington

-1— -}— 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 fihform, fleshy; ribs 

 usually indistinct or obsolete in the fresh plant: commonly some wool among the bases" of the 

 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 

 carinate : corolla-lobes obtuse or hardly acute. — P. juncoides, Lam. 111. i. 342 (Magellan) ; 

 Decaisne in DC. 1. c. 731, partly. P. paucijlora, Pursh, Fl. i. 99; a dwarf form, with short

P. decipiens, Barneoud. Root annual (perhaps sometimes biennial) : leaves from fili-

 sparse or dense (with the scape from 3 to 15 inches h\g\v) : lower bracts commonly ovate- 

 subulate and equalling or exceeding the calyx : sepals ovate-orbicular : corolla-lobes very 

 acute. — Monogr. 16, poorly characterized on a specimen from 'Labrador, but marked as 

 an annual. P. juncoides, Decaisne, 1. c. in part. P. maritima, of U. S. authors generally.
