Monardella odoratissima Benth.
Habit: Subshrub. Stem: 10--45 cm, ascending to erect, sparsely hairy (+- glabrous), rarely to occasionally with sparse, stalked, conical glands; distal stem diam 0.5--1.2 mm. Leaf: 15--50 mm, 5--18 mm wide, lanceolate to ovate, entire, sparsely to densely hairy, green to ash-gray, generally purple-tinged, glands on abaxial face in obvious pits. Inflorescence: flower clusters 1--several per main stem, 12--28(37) mm wide; generally subtended by unmodified leaves; bracts erect, in cup-like involucre, lanceolate to ovate, acute to obtuse, glabrous to woolly, ciliate, scarious, pale +- green or tinged purple to rose. Flower: calyx 6--11 mm, tube appressed-hairy, lobes densely spreading-stiff-hairy or woolly, hairs <= 1 mm; corolla 10--20 mm, white, lavender, or purple.
Note: Ashy-gray, pale, chaffy-bracted, puberulent plants of northeastern Siskiyou Co. that have been identified as Monardella odoratissima subsp. odoratissima intergrade or are intermediate in morphology between subspecies glauca and pallida; if recognized taxonomically, plants in NCoRH with spreading, soft, wavy leaf hairs (and highly variable bract morphology) assignable to Monardella odoratissima subsp. pinetorum (Heller) Epling (study needed).
Unabridged Note: Intergrades with Monardella purpurea (in KR, NCoR), Monardella linoides, Monardella eremicola, and possibly Monardella follettii. Type specimen of Monardella odoratissima subsp. odoratissima is from northern Washington; if recognized taxonomically, ashy-gray, pale, chaffy-bracted, puberulent plants of northeastern Siskiyou Co. assignable to subsp. odoratissima. The distribution of this variant is generally from Little Mount Hoffman (Siskiyou Co.) northeastern to Oregon; more study needed. Variation in California generally as follows: conical glands on stems widespread, but lacking in Wrn and northern SN (southwestern Plumas and northern Sierra cos.); leaf hairs most dense in NCoRH (Glenn and Tehama cos.) and central SN (Madera, Tulare, and northeastern El Dorado cos.); serrate leaves occur in the vicinity of Sonora Pass (Mono and Tuolumne cos.) and near Camel Peak (Plumas Co.), possibly reflecting intergradation with Monardella sheltonii. Leaf blade length-to-width ratio generally < 2 in NCoRH, southern CaR, and northern SN at < 2000 m elevation; leaf blade length-to-width ratio > 3.8 in central SN at > 2000 m elevation (leaf blade width generally negatively correlated with elevation); bract hairs generally least dense in central SN (Mono Co.), most dense in northern NCoRH and lower elevations of southern SN (Madera and Tulare cos.). Plants with only scarious bracts common in Wrn and eastern CaR of Siskiyou Co.
