 1-2-pinnately parted into narrow linear or filiform lobes, or the upper palmately cleft : 

 spike thick arid dense: bracts equalling the (inch or less long) flowers, somewhat dilated : 

 their lobes and calyx-lobes with upper part of corolla crimson to rose-color, or sometimes 

 paler and duller. — California, common along and near the coast from Humboldt Co.

* Bracts abruptlv and strikinglv different from the leaves, much dilated, entire or the lower with

 wise naked : corolla mostly rose-color : cauline leaves linear-attenuate; lower mostly entire and

O. pachystachyus. A span high, scabrous-puberulent and the stem hirsute : bracts an 

 inch long, all the upper entire and oblong, rose-purple as is the (1^ inch) glabrous corolla: 

 tube of the latter much longer than the calyx: galea with conspicuous and slender 

 incurved tip: anther-cells linear-lunate, mucronate-attenuate at base, glabrous. —N. Cali-

O. tenuifolius, Benth. More slender, taller, somewhat pubescent or hirsute : bracts 

 about half inch long, oblong or oval, partly purplish : corolla purplish, half inch long,
