5 MONARDELLA Benth. Lab. 331. 



Low annual or perennial herbaceous or suffrutescent plants

 colored bracts. Calyx tubular, often elongated, 10-13-nerved, 5- 

 toothed : the teeth short, nearly equal, straight ; the throat naked 

 within. Corolla-tube as long as the calyx: the throat glabrous 

 within: the limb somewhat bilabiate, the upper lip two-cleft, the 

 lower 3-cleft, and the lobes all oblong or linear, flat and nearly 

 equal. Stamens 4, more or less unequal, or the lower ones longer, 

 straight, divergent and exserted. Anthers with two parallel cells 

 becoming divergent or divaricate. Style very shortly two-cleft. 



M. villosa Benth. Lab. 332. Somewhat canescent : stems slender, 6-18 

 inches high, branching from a perennial woody base, stiff and erect or as- 

 cending: leaves rather distant, ovate to ovate-lanceolate or oblong, entire, 

 6-12 lines long, all short-petioled : heads sessile, 6-10 lines high, very dense ; 

 bracts broadly ovate to elliptical, 6-8 lines long, 7-9-nerved, villous-ciliate : 

 tinged with purple : calyx 4-6 lines long, pubescent, its short subulate teeth 

 villous : corolla purple to white, pubescent, the tube gradually enlarged 

 from the base and at length a line or more longer than the calyx; the ob- 

 long lobes 2-3 lines long. On dry ridges, southwestern Oregon to'California. 



M. reflexa. More or less cinereous with a minute scurfy puberulence : 

 stems slender, 6-14 inches high, from a woody perennial base, simple, or 

 more or less branched : leaves ovate to lanceolate, 6-12 lines long, not as
