Stems branching from the base, the branches simple, erect or ascending above the decumbent 

 base, about 1 dm. long, slender, strigose. Basal leaves tufted, linear, 2-3 cm. long, pustulate- 

 setose on the margins and the midvein beneath, otherwise glabrous ; stem-leaves usually only 1 

 or 2, strigose ; raceme solitary and simple, about as long as the sterile portion of the stem, 

 loosely flowered, only the lower flowers bracteate ; pedicels densely strigose, the lower about 

 2 mm. long; corolla 1.5-2 mm. broad; calyx-lobes 4 mm. long in fruit, densely strigose-hirsute, 

 and usually rufous at the tip, base of the tube about 3 mm. broad ; nutlet about 3 mm. long, the 

 body somewhat quadrate, abruptly narrowed into a beak-like tip about as long as the body, 

 dorsal keel high and armed partly or throughout with stout spines or processes, the lateral 

 angles also often similarly armed, the processes armed with coarse recurving hairs, ventral side 

 prominently keeled and rugulose especially toward the base, also sometimes spiny ; scar mostly 

 triangular. 



Usually in clay depressions, Upper Sonoran Zone; Redding, Shasta County, southward along the eastern 

 side of the Sacramento Valley and the foothills of the Sierra Nevada to Stanislaus County, California. Type lo- 

 cality: Butte County. April-May.

 Plagiobothrys glyptocarpus I. M. Johnston, Contr. Arnold Arb. No. 3: 37. 1932. 



Annual, stems branching from near the base, branches simple, slender, ascending, 1-5 dm. 

 high, strigose. Lower leaves linear or narrowly spatulate, 4-8 cm. long ; upper leaves oblance- 

 olate to oblong-linear ; racemes simple, loosely flowered, elongated, bracteate near the base ; 

 calyx-lobes becoming 3-5 mm. long ; corolla 5-9 mm. broad ; nutlets narrowly ovoid, about 

 2 mm. long, incurved, acute or constricted above and somewhat beaked ; dorsal side prominently 

 keeled, transverse ridges prominent but irregular, interspaces finely tuberculate, ventral side, 

 keeled down to the scar, the sides with prominent and approximately diagonal ridges ; scar deeply 

 excavated, narrowly triangular, nearly half as long as the nutlet. 



Moist places, along streams. Upper Sonoran Zone; Jackson County, Oregon, to Lake and Butte Counties, 

 California. Type locality: "Moist cultivated ground, eight miles north of Oroville," Butte County, California. 

 March-June. 



Allocarya glyptocarpa subsp. modesta (L M. Johnston) Abrams. {Plagiobothrys glyptocarpus var. modestus 

 I. M. Johnston, Contr. Arnold Arl). No. 3: 38. 1932.) Flowers small, corolla 2-3 mm. broad. Known only

 California.

 Similar to Plagiobothrys glyptocarpus and probably not specifically distinct. Flowers smaller, barely exceeding 

 the calyx and 1-2 mm. broad; nutlet ovoid, much-constricted above the middle, sharply angled, 1.5 mm. long, the 

 dorsal side dentately keeled its entire length and coarsely transverse-rugulose, ventral side keeled from scar to 

 apex. Collected at Madera, California, and known only from the type locality.

Stem branched from the base, the branches prostrate, 1-3 dm. long, straight, slender and 

 somewhat wiry, thinly strigose, often floriferous nearly to the base. Leaves narrovvly linear, 

 the lower 3-10 cm. long, glabrous or nearly so above, thinly strigose beneath, the hairs mostly 

 pustulate at base ; racemes simple, becoming loosely flowered ; mature calyx-lobes usually ac- 

 cresent, 3-8 mm. long, barely 1 mm. wide, connivent or sometimes spreading, more or less 

 definitely curved toward one side ; corolla 1-2 mm. broad ; nutlets narrowly to broadly lanceolate, 

 acute ; dorsal side keeled only above the middle, more or less obliquely or transversely rugose, 

 smooth, granulate or penicillate-hairy ; ventral side keeled down to the basal scar, this hori- 

 zontal or slightly oblique, not surrounded by a ridge, but frequently with a downwardly directed 

 dorsal flange. 



In heavy, usually alkaline soils, Sonoran Zones; Sherman and Malheur Counties, eastern Oregon, to southern 

 Idaho and northern Utah, and south in the central valleys of northern California and coastal valleys of southern 

 California to northern Lower California. Type locality: Pine Creek, Eureka County, Nevada. March-July.
