 and also hispid mostly below the middle with spreading subulate bristles ; nut et solitary, hori- 

 zontal or nearly so, ovoid-acuminate, obcompressed, the surface finely muriculate-papiUose and 

 with scattered tubercles and a few rather obscure rugose ridges, keeled dorsally, ventral side 

 keeled above, the groove below opening with a large triangular deeply excavated scar.

Stems 15-30 cm. high, branching from near the base, the branches rather strict, strigose 

 and also hirsute. Leaves linear or very narrowly oblanceolate, the lower 2-3 cm. long ; spikes 

 U'^ually in pairs on very slender peduncles, dense and conspicuously white-villous when young, 

 elongating to 4-6 cm. in age; pedicels 1-2 mm. long; corolla 3-4 mm. broad; fruiting calyx 

 5-6 mm. long, densely and conspicuously white-villous-hirsute, the lobes erect; nutlets solitary, 

 ovoid, abruptly attenuate above, 2.5 mm. long, the dorsal side rounded on the back, micro- 

 scopically papillate and with a few low obscure tubercles. 



Gravelly or sandy places in creek bottoms, Upper Sonoran Zone; foothills at the head of the Sacramento 

 Valley, Shasta County, California. Type locality: Cow Creek, Shasta County. April-May.

Stems erect, 2-4.5 dm. high, with rather strictly ascending branches, moderately pubescent 

 with rather slender appressed hairs and also similar but a little longer spreading hairs. Leaves 

 linear-oblong to linear-lanceolate, 1-3 cm. long, with appressed or ascending hairs ; spikes gemi- 

 nate or rarely ternate, 5-15 cm. long, often with a flower in the axil of the geminate ones; 

 fruiting calyx 3-5 mm. long, densely hirsute-pilose with straight ascending whitish hairs, the 

 hairs a little longer on the little enlarged midribs but otherwise similar and not at all retrorse ; 

 corolla 2-4 mm. broad; ovules 4; nutlets 1, or rarely 2 or 4, lanceolate-ovoid, 2-2.5 mm. long, 

 smooth or inconspicuously tessellate, low-convex on the back, rounded on the margins ; groove 

 closed down to the forked base ; style extending to about three-fourths the height of the nutlet. 



Gravelly or rocky slopes. Transition Zones; western Siskiyou Mountains, southern Oregon, south in the 

 Coast Ranges to Humboldt and Lake Counties, California. Type locality: between KelseyviUe and Lower 

 Lake, Lake County, California. May-July.

Stems erect with few ascending branches, 1.5-5 dm. high, hirsute. Leaves oblanceolate to 

 linear, acute or obtuse, appressed-hirsute ; spikes commonly ternate, naked or rarely with 1 

 or 2 bracts at base, mostly 5-10, rarely 20 cm. long; corolla conspicuous, 4-7 mm. broad; 

 fruiting calyx 2)-6 mm. long, ovoid, or ovoid-oblong, the lower becoming distant; pedicels 

 about 0.5 mm. long; lobes linear to linear-lanceolate, connivent above with the tips spreading, 

 densely appressed-hirsute on the margins, midribs but little thickened, beset with spreading 

 whitish or slightly yellowish bristles; nutlets 4, or sometimes fewer by abortion, pale, ovoid, 

 acute, 2-3 mm. long, very finely muriculate, with a few low rounded papillae interspersed, low- 

 convex on the back, rounded on the margins; groove closed or very narrow, broadly forked at 

 base ; style reaching to about four-fifths the height of nutlets.
