Hillsides and fields, coloring moist spots with a dull red hue: Oak- 

 land Hills; Marin Co.; Humboldt Co. and northward. Mar.-Apr. 



6. O. floribundus Benth. Erect, somewhat corymbosely branched 

 from near the base or the middle, 5 to 12 in. high, nearly glabrous; 

 leaves (especially the upper) pinnately parted into linear-filiform di- 

 visions, some again parted; spikes short and dense, the upper bracts 

 not surpassing the calyx; corolla white or cream-color, 6 lines long, 

 its tube much exceeding the calyx; lower lip with 2 hairy lines within. 



Hillsides near the coast: Millbrae, Davy; San Francisco, Jepson. 



7. O. faucibarbatus Gray. Herbage greenish, glabrous, or puber- 

 ulent above; 7 to 14 in. high, with ascending branches from the 

 middle; leaves oblong or ligulate at base, pinnately cleft above into 

 several linear divisions; spikes at length elongated and lax; bracts 

 shorter than the flowers, palmately cleft or parted into lanceolate 

 segments; corolla yellow or pinkish white throughout, 9 to 10 lines 

 long, its tube very slender, pubescent, twice the length of the calyx; 

 sacs of lower lip nearly 2 lines deep, deeper than high. 



Low fields in the Coast Range valleys from Monterey Co., Chandler, 

 Santa Cruz, Setchell, to Napa Valley, Jepson, Sonoma Co., and 

 Mendocino Co. Apr. -May. 



8. O. erianthus Benth. Owl's Clover. Herbage, particularly 

 the bracts and stems, reddish; plants 5 to 8 in. high; leaves pinnately 

 divided into filiform divisions; spikes slender; bracts much shorter 

 than the flowers; corolla about 10 lines long and sulphur-yellow 

 except the dark purple subulate galea, its filiform tube at least twice 

 the length of the calyx; sacs of the lip 2 linos deep, deeper than high, 

 each sac commonly with 2 greenish yellow spots at the base of the 

 tooth; folds of the throat densely bearded. 



Very abundant on the plains of the Sacramento and San Joaquin 

 and on the low hills of the Coast Ranges, often coloring wide stretches 

 in Apr. and May. 



Var. versicolor (O. versicolor Greene). * White Owl's Clover. 

 Corolla white, excepting the purple galea, often with a transverse 

 purple band across the throat below the sacs; otherwise like the pre- 

 ceding. — Lake Merced. 



Var. roseus Gray. Corolla rose-color. — San Francisco sand hills. 



9. O. lithospermoides Benth. Cream Sacs. Herbage hirsute- 

 pubescent above, less so below, erect and strict, or with few branches 

 above the base; lower leaves lanceolate, entire; upper oblong, with a 

 few slender lobes; spike very dense and thick; bracts nearly equaling 

 the flowers, the upper dilated at the base, palmatifid into 7 or more 

 narrow lobes; corolla 1 in. long or more, of a rich cream-color, 

 strongly 3-saccate, the tube dilated upwards. 



Plains and low hills: Contra Costa and Marin Cos. northward 

 through the Coast Eanges to Mendocino; Sacramento Valley. Last 

 of Apr. to first of June. Upper bracts large, almost as broad as long, 

 concealing the calyx; in the two preceding species the upper bracts 

 are small, little or not at all longer than the calyx, only 3 to 5-cleft 

 and not so broad.
