l66 EVENING PRIMROSE FAMILY 



7. E. ursinum var. subfalcatum Trel. Plant very slender, 

 6 to 18 in. high, crisp-hairy throughout. Leaves sessile, nar- 

 rowly ovate, somewhat toothed, mostly obtuse, Y to Y\ in. 

 long. Petals white or lavender, about l /§ m - long. — A rare 

 species : Hog Ranch, to Yosemite and Little Yosemite val- 

 leys. Slightly hairy forms approach no. 6 but are smaller and 

 more slender. 



8. E. glaberrimum Barb. Stems 1 to 2 ft. high. Herbage 

 glabrous throughout, covered with a bloom. Leaves narrowly 

 lanceolate, rather obtuse, entire or very obscurely few- 

 toothed, 1 to 2 in. long, narrowed at base but scarcely petioled. 

 Petals nearly white, over % i n - long? notched at summit. — A 

 common species of moist places, first described from speci- 

 mens collected in the Yosemite Valley. 



9. E. alpinum L. Plant 9 to 18 in. high, minutely crisp- 

 hairy among the flowers. Leaves thin, light green, broadly 

 elliptic, mostly obtuse, nearly entire, 34 to 2 in. long. Petals 

 white or rosy-tipped, y$ in. long, deeply notched. — Moist 

 banks at Glacier Point and probably at other high altitudes. 



E. hornemanni Reich., of the northern Sierra Nevada, may 

 be expected; like E. alpinum but more pubescent, the petals 

 twice as large and violet or lilac, the leaves dark green or 

 purplish. 



10. E. oregonense Haussk. A delicate plant, 6 to 18 in. 

 high, glabrous below, obscurely pubescent above. Leaves 

 lanceolate, almost entire, very obtuse, Y\ to Y\ in. long. 

 Flowers few, strictly erect. Petals about *4 m - l° n g> deep 

 violet. Var. gracillimum Trel. has white flowers less strictly 

 erect (E. pringleanum Haussk.). — Moist places, as in Yo- 

 semite meadows and along the upper Tuolumne. 



4. ZAUSCHNERIA. 



1. Z. californica Presl. California Fuchsia. Balsamea. 

 Herbage gray-pubescent. Leaves lanceolate, acute, Yz to V/z 

 in. long. Flowers 1 to \ l /z in. long (above the ovary), the 

 funnelform calyx as well as the 2-cleft petals scarlet. Sta- 

 mens exserted. 



In late summer and autumn many a rocky slope is ablaze 

 with this scarlet-flowered, gray-foliaged perennial, the range 

 of which extends from the foothills to about 6500 ft. alt. 

 The ease with which it is grown and its high ornamental value 

 make it a suitable garden plant where masses of late bloom 

 are desired. As yet, however, it is but little known among 

 garden people.
