In tlio Sierra Novailn, IVoni Tulnns (!oiiiitv nortliwiird, nt iiii iillitiido of 8,000 to 1] 000 fpct 

 {Brewer, Bolnvder, Tnrrei/, Muir, Ro/krock) ; also in tlio East Ilnnil.oldt Mountains, 'Nnvada, 

 IVatsmi. A cliarming alpine species, connecting tliis section (C'/inmimrrion) with tlie others of 

 the genus. 



E. LATiFOMUM, Linn., of Europe and Asia, differing from E. spicntnm in its short ascendinsr 

 oecasionally branched stem, ovate-lanceolate somewhat pubescent rather thick and ri<^id leaves, 

 veins not apjmrent, very large axillary and terminal flowers on short pedicels, and tho'somowhat 

 erect ^dahvons style shorter thnu the staiuens, is found from Arctic America to the higher moun- 

 tains m Colorado and perhaps reaches California. The 7i'. opactim, Lvhrn. in Hook. El. i. 205 

 from the banks of the Columbia (Doiujlns, Scou/rr), with erect pubescent stem, narrowly lanceo- 

 late leaves, and the flowers of E. latifolium, may be a hybrid between it and E. spkntum. 



E. LUTEUM, Pursh, may be mentioned as our only other allied species, and remarkable in the 

 genus for its large yellow flowers. It ranges from Alaska to Oregon. 



* * Flmvers small: petah, sUimem, and ^tyle erect: stir/7tm clavate or cylindrical: 

 limb of llie calyx \-cleft. 



+- Herbaceous perennials. 



++ Leaves not strictly sessile : more or less pubescent. 



3. E. Watsoni, IJarbey. Iloary-pubescent throughout: roots spreading in raud, 

 with stolons (I): stems terete, branching, about 18 inches high: leaves oblong- 

 lanceolate (the length thrice the width), denticulate-.serrulate. shortly petioled": 

 petals elongated obcordate, comparatively narrow : stigma cylindrical and not ex- 

 panded : seeds granulately furrowed. — Mon. Epilob. inod. t. 0. 



Near the Ihissian settlement, Sonoma Co. ; only from Hussinn collectors, 'i'he (lowers are of 

 medium size. Much resembling^, hirsidnm, Linn., differing in its smaller petals, cylindrical 

 not e.\panded stigma, furrowed seeds, and leaves not clasping. 



4. E. coloratum, Muld. Roots spreading in rich wet soil : stem nearly terete, 

 erect, 1 to 3 feet high, much branched, puberulent : leaves mostly opposite, lanceo- 

 late, acute, on very short petioles, denticulate-serrulate, the veins often reddish : 

 flowers small, purplish : stigma clavate : capsules on short pedicels, slightly pubes- 

 cent. — Barbey, Mon. E})ilob. iued. t. 9. 



Throughout the Sierra Nevada, nnd to the Cniamaca Mountnins (Pnlwrr) ■ also northward and 

 eastward through the Northern United Stiites. With better materinl it is probable thnt the 

 I'n(!ilic form will have to bo distinguished from the eastern by the form of (he seeds, the L'labroug 

 teeth of the leaves, kc. • 



5. E. alpinum, Linn. Alpine: roots capillary, with occassionid (ilifonn stolons: 

 stems creeping at the base, 2 to 6 inches high, usually with two pubescent lines : 

 leaves opposite, ovate or ovate-oblong, obscurely denticulate or nearly entire, hardly 

 petioled, glabrous : flower-buds ovoid : sepals hairy, not acuminate : petals pale rose- 

 color, with a few hairs on the outer surface, little longer than the calyx : anthers 

 nearly spherical; fdamonts broader at base: stigma undivided: capsules long, thick, 

 purple, often partly nodding, as also the top of the plant : seeds rather rounded at 

 the top. 



In the Sierra Nevada ; Westfall's Meadows {Bnlandc.r) ; near Soda Springs, nt 9,000 feet alti- 

 tude, Brrurr. Throughout the northern iiart of the continent, as well as Northern Europe and 

 Asia. Distinguished from the following elostdy allied species by its ovoid buds. 



6. E. origanifolium, Lam. Roots spreading on the banks of alpine rivulets, 

 Avith occasional stolons : stem generally simple, terete, with two pubescent lines, 6 

 to 12 inches high : leaves mostly opposite, moro or lo.^s petiolod ; the lower rounded, 

 the middle ones oval and ocpially iminted at each (Uid, the upper acuminato : buds 

 somewhat angular at the base : flowers largo, varying from dark purple to pure 

 white : sepals half the length of the obcordate jmtals : capsules sometimes nodding: 

 Roed.s rather long-acuminate nt both ends, somewhat lighf colored.
