MINT FAMILY 437 



obscure; bracts ovate to lanceolate or often attenuate above, pinkish or purplish- 

 tinged, pubescent, 3 to 6 lines long, the lower often somewhat foliaceous, ciliate 

 towards base, the upper membranous, ciliate; calyx 3i/^ to 4% lines long, more or 

 less pubescent, the acute teeth white-hirsute without and within; corolla white, 

 sometimes varying to rose-color or lavender, its tube more or less pubescent witliout 

 and within, the expanded upper end of tube exserted from calyx, the lower lip 2 

 lines long, slightly exceeding the upper, about 1/2 the length of the tube, upper lip 

 cleft for about % its length ; stamens commonly slightly hairy at base, the longer 

 pair exceeding the corolla-lobes. 



Montane slopes and rocky ridges, 2300 to 9000 (or 11,150) feet : North Coast 

 Ranges from Mendocino Co. to western Siskiyou Co.; Sierra Nevada from Tulare 

 Co. to eastern Siskiyou Co. ; White Mts. East to New Mexico and Colorado, north 

 to Washington. June- Aug. 



Note on variation. — Next to Monardella villosa, Monardella odoratissima is the most variable 

 species of its genus in western America. Of all our perennial species of Monardella, it has by 

 far the widest geographic distribution. Variation affects chiefly breadth of leaf, pubescence, and 

 the number, size and shape of the outer or foliaceous bracts of the head. Variation in size of the 

 heads is less marked. Variations in leafage, pubescence and bracts are, however, continuous and 

 often terminate in a striking form, but forms of this sort are incapable of morphological delimita- 

 tion and are usually without definite geographic significance. In the high Sierra Nevada, Monar- 

 della odoratissima is a frequent species everywhere, sometimes filling great open spaces in the 

 forest, especially on ridges or plateaus. It is eagerly browsed by sheep. The leaves are used for 

 a tea by shepherds in the White Mountains.
