304 LIL.IACEAE 



High montane in northern Humboldt Co. and in Siskiyou Co. North to 

 British Columbia. 



Locs. Trinity Summit, Jepson, 2039; Marble Mt., Jepson 2826. 



Refs. ERYTHRONIUM GRANDIFLORUM Pursh, 1:231 (1814), type loc. Kamiah, Ida., Lewis; 

 var. PARVIFLORUM Wats. Proe. Am. Acad. 26:129 (1891), based on high montane spms. from 

 the western U. S. E. parviflorum Gooding, Bot. Gaz. 33:67 (1902). 



5. E. californicmn Purdy. FAWN LILY. Like preceding but leaves strongly 

 mottled ; flowers creamy white or somewhat yellowish, or white ; median sacs 2, 

 the lateral ones reduced to a transverse ridge. 



Brushy or open hillslopes: northern Sonoma Co. to Humboldt and Trinity 

 cos., 500 to 3500 feet. Mar.-Apr. 



Locs. Gualala Eiver, M. S. Baker; Cloverdale, 'Setchcll ; Middletown grade, Jepson; Wil- 

 lits, W. C. Matlieios; Blue Roek Eidge, Jepson 1880; Harris, Ethel Tracy; Kneeland Prairie, 

 Tracy 4897 (flowers white) ; Burnt Eanch, aee. to Purdy. 



Eefs. ERYTHRONIUM CALIFORNICUM Purdy, Flora and Sylva, 2:253 (1904), type loc. 

 Ukiah, Purdy. E. grandiflorum Wats. Bot. Cal. 2:170 (1880), not Pursh. Purdy 's species 

 seem insufficiently distinct from the northern plant usually called E. giganteum Lindl. (Bot. 

 Eeg. sub. t. 1786, 1836, type loc. "Northwest America," Douglas), but he restricts the true 

 E. giganteum to the region from Grants Pass, Ore., north to British Columbia. 



E. HOWELLII Wats. Proe. Am. Aead. 26:130 (1891). Flowers light yellow, in age pale rose, 

 "without auricles or scales." Type loc. Waldo, Ore., Howell. Specimens of both Howell's 

 first and second distribution show auricles and sacs ("scales"). On the other hand Purdy 

 states that specimens from the Adams Mine 1 mile sw. of Waldo, probably the exact type 

 station, are "entirely destitute of appendages." 



6. E. revolutum Sm. Like E. californicmn; scapes 1 or 2 (to 4) -flowered, 

 7 to 1 2 inches high ; leaves lightly mottled ; flowers bright pink or pale lavender, 

 sometimes white, aging to purple; filaments broadly dilated, almost conniving 

 around the ovary. 



Woods, often on borders of swamps : Mendocino and Humboldt cos., 10 to 20 

 miles from the coast, 500 to 2500 feet. Northward to British Columbia.

 Bald Mt., Tracy 4938; Hupa, Chandler 1279. 



Eefs. ERYTHRONIUM REVOLUTUM Smith, Eees' Cycl. 13. no. 3 (1809), type loc. Gulf of 

 Georgia, British Columbia, Mcnsies. Var. bolanderi Wats. Proe. Am. Acad. 26:129 (1891), 

 type loc. Mendocino redwoods, Bolander. 



1. E. hartwegii Wats. Flowers solitary or borne in a 2 to 5-flowered umbel 

 sessile between the pair of basal leaves, each flower thus appearing to be raised 

 on a scape of its own ; scape-like pedicels 3 to 6 inches high ; corms forming 

 offsets freely at the end of filiform filaments originating from their base ; leaves 

 richly mottled ; flowers white or cream with orange or yellow base ; inner perianth- 

 segments with a median pair of compressed sacs and with prominent auricles; 

 stigma 3-lobed or -parted. 



Brushy hillsides : Sierra Nevada foothills, Tehama Co. to Mariposa Co. Apr. 

 Our only species which has offsets. 



Locs. Eough and Eeady, Nevada Co., Jepson; Auburn, Bolander; Mariposa, Congdon. 



Eefs. ERYTHRONIUM HARTWEGII Wats. Proe. Am. Acad. 14:261 (1879), resting first on 

 E. grandiflorum Benth. PI. Hartw. 339 (1857), type loc. Sierra Nevada foothills in Tehama 

 Co., near Pine Creek, Eartweg 288. 



19. FRITILLARIA L. 



Stem erect, simple, from a bulb of one or few thick fleshy scales. Cauline 

 leaves alternate or whorled, narrow, sessile; basal leaves large, ovate or elliptic, 

 home only in the year or years before the flowering stalk appears. Flowers in 

 racemes or solitary, dull purple, brownish, whitish or red. Perianth campanulate 

 to funnel-form, deciduous, of 6 distinct segments, each segment usually with a 

 shallow gland or nectar-bearing area above the base. Stamens 6, inserted on the 

 base of the segments, included ; filaments slender ; anthers extrorse, more or less
