Labrador and Newfoundland, Pitrshl Between Lakes St. Clair and Hu-

 Douglas is perhaps a variety of A. stricta.

 leaves subulate, canaliculate, pungent, the lower ones squarrosely imbricated 

 and crowded ; flowers few, subpaniculate ; sepals lanceolate, obscurely 3- 

 nerved, longer than the oblong-ovate petals. 



"Summits of hills in the Rocky Mountain range (lat. 41°).— If Stems 

 about 4 inches high, forming considerable ca^spitose tufts. Leaves rigid, 3- 

 nerved. Sepals unusually long and acute." A^iii/.— Nearly allied to A. verna. 



-f^ 8. A. squarrosa (Michx.) : densely ca;spitose ; stems minutely glandular- 

 pubescent, few-flowered ; leaves short, subulate-canaliculate, the lower ones 

 densely squarrose-imbricate, rather obtuse, upper ones few ; petals about 3 

 times the length of the ovate, very obtuse, nerveless sepals. — Mick.r. ! fl. 1.

 ceous. Capsule ovate, obtuse, 3-valved, longer than the calyx. Styles some-

-/-^. A. stricta (Michx.) : dlff"u3ely caespitose, glabrous, branched from the 

 base ; leaves subulate-setaceous, 1-nerved, much fascicled in the axils ; pe-

 se-pah.—Mich:r. ! fl. 1. p. 274; Ell. sk. 1. p. 520; DC. prodr. 1. p. 503. 



a. Strict, few-flowered; leaves erect, crowded, longer than the internodes. 



0. diffusely spreading ; leaves spreading or recurved, often shorter than 

 the internodes ; branches of the cyme spreading. — A. stricta, Bigel. ! fl.

Rocks and barren ground, Canada ! to S. Carolina and Arkansas ! and 

 north to the Arctic Sea (//"ook) May-July.— 2^ Stems 3-10 or 12 inches 

 high. Capsule about as long as the calyx.— The van U. is by far the most 

 common in the United States, and has very slender peduncles and pedicels; 

 but the plant varies according to situation, &c. 



"f" 10. A. tenella (Nutt. ! mss.) : " erect, slender, somewhat branched from 

 the base ; leaves fihform- subulate, acute ; peduncles minutely glandular-pubes- 

 cent; petals oblong, nearly twice the length of the acute 3-nerved shortish 

 sepals. 



" Rocky places, plains of the Oregon ! and Arkansas.— (l) Allied to A. 

 tenuifolia,' but with the petals larger and the leaves longer." Nutt. — We have 

 this pi mt also from Dr. Scouler under the name of A. stricta, to which spe- 

 cies it is doubtfully referred by Hooker. The leaves are scarcely if at all fas-
