Stems branched from the base, decumbent or ascending, rarely erect, 1-4 dm. long, usually 

 rather thinly strigose. Lower leaves linear, the lower 4-10 cm. long, the upper linear or linear- 

 oblanceolate ; racemes slender and elongated in age, bracteate below ; pedicels about 1 mm. 

 long or the lowermost longer, ascending ; calyx more or less accrescent ; lobes lanceolate, 2-4 

 mm. long, ascending ; corolla 1-3 mm. broad ; nutlets 2 mm. or less long, oblong-ovoid ; dorsal 

 side somewhat keeled above the middle, the surface granulate, the sides with somewhat oblique 

 transverse ridges or wrinkles, these below the middle becoming more or less obscure and often 

 replaced by tuberculations, interspaces narrow and sparsely or not at all tuberculate ; ventral 

 side keeled to well below the middle ; scar small, oblique or almost basal, ovate to elliptic or 

 cuneate, concave, surrounded by an irregular ridge. 



Dry beds of pools and ditches, Upper Sonoran and Transition Zones; Douglas County, Oregon, southward 

 west of the Cascades and the Sierra Nevada to northern Lower California. A common and variable species. Type 

 locality: "In wet places, Umpqua Valley Oregon." April-June.

Stems branching from the base, prostrate or loosely ascending, 5-40 cm. long, strigose. 

 Leaves appressed-hispidulous, the hairs somewhat pustulate, the upper surface sometimes glab- 

 rate ; lower linear, the upper linear or linear-oblanceolate ; racemes slender, usually elongated 

 and loosely flowered in age, leafy-bracted at least to the middle ; pedicels 1 mm. long or the 

 lowermost sometimes 5-10 mm. long; calyx more or less accrescent in age, strigose or ap- 

 pressed-hispidulous ; lobes linear to narrowly lanceolate, 2-3 mm. long, rarely less, ascending ; 

 corolla 1-2 mm. broad; nutlets 1.5-2 mm. long, ovoid to ovoid-lanceolate, abruptly rounded 

 and somewhat angulate at base ; dorsal side keeled above the middle, rather closely and obliquely 

 transverse-ridged, the ridges often anastomosing, both the keel and the ridges often muriculate 

 and frequently dentate with papillae, or with minute hyaline more or less branched hairs, 

 lateral angles keeled ; ventral side keeled and angulate to below the middle ; scar linear-oblong, 

 lateral usually concave, encircled by a ridge. 



Moist meadows or flats, Canadian and Transition Zones; Washington mostly east of the Cascades to Idaho, 

 south to Oregon both west and east of the Cascades, and California in the North Coast Ranges and Sierra Nevada
