 rather stout : stems many, loosely matted and much branched near the base ; branches 

 ascending or erect, leafy : leaves subulate-acerose, rigid, pungent, tending to be squarrosely 

 spreading, connate, 3 to 4 lines long ; flowers usually numerous in spreading cymes, rarely 

 subsolitary : sepals attenuate, acuminate, often purplish, not strongly nerved, 2 to 2J lines 

 long, exceeding the more or less pointed petals and ovoid capsule. — Pax in Engl. Jahrb.

-1— Alpine, boreal, or arctic species. 



++ Petals oblong or narrowly obovate. 



A. Sajanensis, Willd. Cespitose : stems finely but rather densely glandular-hirsute, 

 decumbent, very leafy below and with age sheathed at the base with the dried persistent 

 leaves ; the upper more or less erect portion of the stems 6 lines to 2| inches in length, 

 bearing two or three pairs of short and rather distant more or less puberulent leaves, and 

 terminating in 1 to 3 flowers ; lower leaves linear, obtusish, rather rigid, erect, 2 to 3| lines 

 long, quite glabrous or ciliolate, less commonly gland ular-puliescent, straight: segments of 

 the calyx linear oblong, 1-3-ribbed, glandular-pubescent, 2 lines in length : petals spatulate, 

 equalling or half exceeding the sepals, rarely almost twice as long (but narrower than in 

 A. arctica) : valves of the capsule linear-oblong, obtuse, often considerably exceeding the 

 calyx. — Willd. in Schlecht. Berl. Gesell. Nat. Fr. Mag. vii (1816), 200; DC. Prodr. i. 408.
