BORAGE FAMILY 567 



nutlets ovoid or lanceolate-ovoid, 1.5-2 mm. long; dorsal side finely granulate, keeled toward 

 the apex, ridges evident or obscure, more or less diagonal and frequently anastomosing, toward 

 the base more or less reduced to tubercles, interspaces sparsely tuberculate; ventral side keeled 

 almost to base, with or without ridges or wrinkles ; scar ovate to elliptic, suprabasal, or on the 

 oblique basal portion of nutlet. 



Wet places. Humid Transition Zone; Vancouver Island, and the Olympic PeninsiJa, Washington. Type 

 locality: "N.W. Coast, Dr. Scouler." May-July.

Plagiobothrys cognatus I. M. Johnston, Contr. Arnold Arb. No. 3: 59. 1932. 



Stems usually branched at base, erect or spreading, 5-25 cm. long, rather finely appressed- 

 pubescent or strigose. Leaves strigose and pustulate beneath, less so or glabrate above, the 

 lower 2-7 cm. long, the upper shorter, often linear-spatulate ; racemes simple, slender, usually 

 loosely flowered, bracteate throughout or usually only below the middle ; pedicels 1 mm. long 

 or often less, erect or ascending ; corolla 1-2 mm. broad ; nutlets oblong-ovoid to broadly ovoid, 

 about 1 . 5-2 mm. long, somewhat constricted and acute at apex, obtuse or rounded at base ; 

 dorsal side keeled down to about the middle or below, with irregular transverse ridges, these 

 often reduced to scattered tuberculations or entirely absent toward the base, surface finely granu- 

 lated or sometimes with glochidiate bristles ; ventral side keeled down to the basal ovate scar, 

 the sides diagonally ridged or wrinkled, especially above the middle. 



Damp flats or borders of meadows, often in alkaline soils. Upper Sonoran and Arid Transition Zones; north- 

 eastern Washington and Idaho southeast of the Cascades, through eastern Oregon to the Sierra Nevada, central 

 California, Nevada, Utah and northern Arizona. Type locality: Cache Valley, Utah. June-Aug.

Plagiobothrys Cusickii I. M. Johnston, Contr. Arnold Arb. 3: 63. 1932. 



Stems branched from the base, slender, prostrate or ascending, 5-20 cm. long, sparsely 

 strigose. Leaves strigose beneath, the hairs pustulate at base, upper surfaces nearly or quite 

 glabrous, the hairs often more abundant and more spreading on the margins, lower linear, 

 3-10 cm. long, upper shorter, linear to lanceolate; racemes solitary, slender, loosely or some- 

 times densely flowered, bracteate at least below the middle; pedicels 1 mm. long or less, 

 slender ; calyx finely appressed-hispidulous, only slightly accrescent in age ; lobes linear or 

 linear-lanceolate, 1.5-4 mm. long, erect or ascending; corolla 1-1.5 mm. broad; nutlets lanceo- 

 late to oblong-ovoid, 1-2 mm. long, usually abruptly angled at base; dorsal surface glossy, not 

 granulate, keeled near the apex, with irregular more or less oblique ridges, tuberculate in the 

 interspaces and toward the base; ventral side keeled to well below the middle, oblique toward 

 the base and bearing the deep small scar; axial nutlet firmly attached with a broad ovate or 

 deltoid scar. 



Alkaline soils. Arid Transition and Upper Sonoran Zones; east of the Cascades in Washington and Oregon 

 to northeastern California, east to Idaho and Nevada. Type locality: "Union County, Oregon" and "Reno, 

 Nevada." May-Aug.

 Allocarya hispidula var. tenera Jepson, Fl. Calif. 3: 365. 1943. 



Stems branching from the base, spreading or ascending, very slender, 6-15 cm. high, sparsely 

 and inconspicuously strigose. Basal leaves narrowly linear-oblanceolate, about 2 cm. long, 1-2 

 mm. broad, sparsely pustulate-setulous on the margins and midvein, stem-leaves few, narrowly 

 linear, 5-15 mm. long; racemes bractless or bracteate only at base; pedicels, at least the lower, 

 slender, 1-2 mm. long ; corolla 3-7 mm. broad ; fruiting calyx-tube distinctly 4-ribbed, the lobes 

 erect, 1.5 mm. long, narrowly linear-lanceolate or the margins involute, strigose; nutlets ovoid 

 about 1 mm. long, reticulate-rugulose, the ridges thin and tuberculate-roughened on the mar- 

 gins ; interspaces finely tuberculate, ventral side diagonally rugulose, keeled above the scar, 

 this lanceolate-ovate, extending from the base almost to the middle of the nutlet. 



Wet places, mostly Upper Sonoran and Arid Transition Zones; Modoc and Shasta Counties south in the 

 North Coast Ranges to Lake County, California. Type locality: Adams Springs, Lake County, California. May- 

 July.
