18. N. squarrosa H. & A. Skunkweed. Stem erect, branching at or above 

 the base, 8 to 16 inches high; herbage pubescent and noxiously glandular; leaves 

 1/2 to 1% inches long, once or twice pinnatifid, the rigid segments lanceolate and 

 often crowded; calyx 5 to 6 lines long, thinly villous (especially on the lobes), the 

 tube broadly searious between the ribs, the lobes lanceolate and pungent, usually 

 entire, a little longer than the tube ; corolla blue, sometimes very pale, 5 to 6 lines 

 long, little or scarcely at all exceeding the calyx; stamens included in corolla-throat, 

 the filaments unequal ( I/2 to 1 line long) , unequally inserted about middle of corolla- 

 tube, the longer usually inserted higher ; capsule many-seeded, the seeds small, 8 to 

 14 in each cell. 



Dry clay or sandy flats in valleys and on caiion flooi-s and opens m forest, 20 

 to 2300 feet : Coast Kanges (mostly the outer and middle ranges) from Monterey 

 Co. to Del Norte Co.; northern Sierra Nevada foothills from Amador Co. to Eldo- 

 rado Co. North to British Columbia. June-Aug. 



Field note. — A vegetatively vigorous type, Navarretia squarrosa, in branching, in foliage and 

 in calyces, is somewhat distinctively marked and in consequence readily kno\Tn by its field habit. 

 It is of frequent occurrence. In early stages of growth, as found in the beds of former shallow 

 winter pools, the aspect is curiously like that of young Centromadia pungens (Hemizonia pun- 

 gens). For the virility of this species there is some evidence: it has emigrated to the state of 

 Victoria, Australia, where it is now an established weed.

 ton 1136 ; Sweetwater Creek, Eldorado Co., K. Brandegee. The var. agrestis Brand has 3 of the 

 calyx-lobes with 1 or 2 spinose teeth near apex; it is not otherwise different. — Mt. Davidson, San 

 Francisco, Jepson 10,595 ; San Mateo Co. Spinose calyx -lobes or the lack of them is so frequently 

 a weak, a variable or immaterial character in Navarretia that occurrence of spinose calyx -lobes in 

 N. squarrosa is to be expected anywhere within the range of the species (as at Englewood, main 

 Eel River).
