Stem stiffly erect, slender, frequently branch- 

 ing 1.5-5 dm. high, bulbiferous at base. Basal 

 leaves 1 or 2, narrowly linear, 10-20 cm. long, 

 2-5 mm. wide ; cauline leaves 1 or 2, attenuate, 

 4-8 cm. long; flowers in 2-3-flowered umbels 

 or in robust plants a few scattered down the 

 stem on lateral branches; bracts 3-10 cm. long; 

 pedicels 6-15 cm. long; sepals about equalling 

 the petals, oblong-lanceolate acuminate, the tips 

 at length more or less recurved, yellow within ; 

 petals fan-shaped, 25-35 mm. long and as broad, 

 deep yellow and more or less penciled with 

 brown, hairy over the lower third of the inner 

 surface with yellow hairs ; gland broad, lunate, 

 densely covered with matted ascending yellow 

 liairs ; anthers oblong, obtuse, pale yellow, 8-10 



mm. long; filaments slender scarcely dilated below, equalling or little exceeding the anthers; 



capsule linear-lanceolate, attenuate at apex, 35-50 mm. long. 



Open hillsides in dry or gravelly ground, Upper Sonoran Zone; California Coast Ranges from Mendocino 

 to San Luis Obispo Counties, also in the foothills of the Sierra Nevada, but here it is usually replaced by the 

 varieties. Type locality: California, probably Monterey. 



Calochortus luteus citrinus S. Wats. Petals deep yellow with a prominent dark brown spot near the base, 

 not oculated. This variety is best developed in the north Coast Ranges of California, in Mendocino and 

 Sonoma Counties, but it also occurs less clearly defined in the foothills of the Sierra Nevada. 



Calochortus luteus oculatus S. Wats. Petals pale creamy white to lilac, with a prominent central dark 

 spot surrounded by a band of yellow; sepals also with an eye-spot. Best developed in the Sierra Nevada 

 foothills from Shasta to Butte Counties, but also found in the north Coast Ranges, California.

 bracts 2)-7 cm. long, scarious-margined below ; 

 pedicels rather stout, 5-20 cm. long; sepals oblong- 

 lanceolate, long-acuminate, the tips at length revo- 

 lute, 25-35 mm. long with a brownish spot sur-
