Monardella sheltonii Torr.
Habit: Subshrub, erect, open, +- glabrous, rhizomed. Stem: +- glabrous. Leaf: 16--34 mm (including petiole, 3--4 mm), 8--11(15) mm wide, lanceolate, entire to weakly toothed, adaxially +- glabrous, abaxially densely, minutely, evenly puberulent (hairs < 0.05 mm). Inflorescence: flower cluster 1 per main stem, 10--29 mm wide; bracts 7--17 mm, 4--8 mm wide, exceeding calyx, inconspicuously or not ciliate, cilia generally < 0.5 mm; outer bracts +- leaf-like, only slightly modified, strongly reflexed; innermost bracts linear to ovate. Flower: calyx 6--8 mm, lobes not or slightly hairier than tube; corolla (12)15--20 mm, purple.
Ecology: Rocky openings, montane forest, oak woodland, chaparral, often serpentine; Elevation: 425--1600 m. Bioregional Distribution: KR, s CaR, n SN. Flowering Time: Jun--Aug Note: Difficult to distinguish. Intergrades extensively with Monardella villosa subsp. villosa (into KR, possibly Oregon) and Monardella odoratissima subsp. pallida (in SNH). Likely best treated as an infraspecific taxon but relationships unclear. Study needed.
Unabridged Note: Has been applied to many intergrading specimens. Many plants attributed to this taxon appear to be intermediate between Monardella villosa and Monardella odoratissima subsp. pallida. May warrant recognition as a infraspecific taxon of Monardella odoratissima because of its short hairs and the predominant portion of its range in northern SN. Like Monardella odoratissima subsp. pallida and Monardella villosa, has long, reflexed leaves immediately subtending flower clusters. Can be separated from Monardella odoratissima subsp. pallida by the short hairs or absence of hairs on the bracts and by the glands of the leaves (and elsewhere), which are at the surface of the epidermis, not sunken in pits. Conspicuous golden spheres of exudate (still "liquid" after 50+ years!) are above each gland. In both Monardella odoratissima subsp. pallida and Monardella odoratissima subsp. glauca, the glands are sunken in pits and the exudate does not form clear spheres, but fills the bowl of the pit like soup. Like Monardella villosa except that it lacks the long hairs and the short hairs appear denser; both taxa have the surface glands and exudate spheres.
