EPILOBIACE^. 209 



rounded to the sliort petioles : fl. few, small, erect ; petals very pale, or 

 deeply colored : capsules slender, erect, on slender peduncles aboiit 

 equalling the floral leaves :• seeds abruptly short-appendaged, from 

 smoothish to notably rough. — Not known as Oalifornian except in n. 1417, 

 Breioer, which came from Mt. Shasta or near there. 



13. E. al pi II mil, Linn. Sp. PL i. 348 (1753), in part ; Trel. 1. c. 108. t. 

 44. Like the last, but with less obvious pubescence : leaves thin and 

 delicate, all gradually narrowed to the slender petioles : fl. white or 

 rose-tinted : capsules very slender, on peduncles often stoutish and as 

 long as the capsules : seeds smooth, with a very manifest beak. — Scarcely 

 known as Oalifornian, yet likely to be found anywhere in the high Sierra. 



14. E. OregOiiense, Hausskn. Monogr. 276 (1884) ; Trel. 1. c. 109. t. 25. 

 Low, simple and stoloniferous, the stem erect to the summit ; inflores- 

 cence sparingly glandular-pubescent, the plant otherwise glabrous : 

 leaves crowded below, remote and very small above, suberect, ovate- 

 lanceolate, or the uppermost linear, very obtuse, remotely denticulate, 

 somewhat tapering to the sessile base : fl. few, erect, small, deep purple: 

 capsules stoutish, surpassing the summit of the stems, their peduncles 

 far exceeding the floral leaves : seeds smooth, obtuse, beakless. — A 

 northern species, to which Prof. Trelease refers somewhat doubtfully 

 certain alpine plants collected by Bolander (n. 4965) and Lemmon, along 

 our northeastern borders. 



15. E. anagallidifollum, Lam. Encycl. ii. 376 (1786) ; Trel. 1. c. 110. 

 t. 47. Very low, cespitose by the numerous stolons, the very slender 

 stems ascending, nodding at summit ; pubescent in lines, the inflores- 

 cence somewhat glandular : leaves small, uniformly distributed, narrowly 

 ovate or oblong, rather obtuse, entire or sparingly denticulate, cuneately 

 narrowed, the lowest wing-petioled : capsule narrowly linear, long and 

 slender, the peduncles long or short ; seeds somewhat obo void-fusiform, 

 short-beaked.— Common by alpine brooklets in Washington and Oregon; 

 reaching Mt. Shasta, and doubtless coming within our limits northward. 



16. E. obcordatuiii, Gray, Proc. Am. Acad. vi. 532 (1865); Trel. 1. c. 

 84. t. 6. Somewhat cespitose, the stems stoutish, ascending or decumbent, 

 3—10 in. long : herbage glabrous, very pale and glaucous, the inflores- 

 cence glandular-puberulent : leaves all opposite, broadly ovate, % — % 

 in. long, repand-denticulate, rounded to very short winged petioles : 

 fl. few, large, slender-peduncled, in the axils of the scarcely reduced 

 upper leaves : petals obcordately 2-lobed, I3 in. long or more, rose- 

 purple : capsule ?4 -1 in. long, subclavate, pedicellate, few-seeded : 

 seeds finely papillate. — Common on moist slopes below perpetual snow, 

 etc., near the highest parts of the Sierra Nevada, from Tulare Co., north- 

 ward ; our most beautiful species. July — Oct. 



* * Perennial; fl. large, somewhat irregular ; style and stamens declined. — 

 Genus Cham^enekion, Tourn., S. F. Gray.
