Monardella purpurea Howell
Habit: Subshrub, erect, open, +- glabrous. Stem: 10--40 cm, dark purple (green), shiny, internodes generally >= leaves. Leaf: 12--30 mm, 5--10 mm wide, lance-oblong, shiny, deep purple to green, leathery, margin entire (serrate). Inflorescence: flower cluster 1 per main stem, 15--25 mm wide, obscurely gland-dotted; outermost bracts 9--13(14) mm, 5--7 mm wide, leaf-like (in color, texture), generally narrowly lanceolate; remaining bracts +- ovate, leathery, purple-tinged, glabrous (hairy), strongly ciliate; cilia multicellular, generally 0.3--0.8 mm. Flower: calyx 6--8 mm, tube slender-stalked-glandular (hairs <= 0.7 mm), sometimes also nonglandular-hairy (hairs multicellular), lobes and sinus area stiff-hairy, purple; corolla 12--16 mm, exserted, rose or purple.
Ecology: Rocky slopes, generally on serpentine or related bedrock, chaparral, woodland, montane forest; Elevation: 400--1400 m. Bioregional Distribution: KR, NCoRO, SnFrB; Distribution Outside California: Oregon. Flowering Time: Jun--Jul
Unabridged Note: In California, distributed from Del Norte and Siskiyou cos. to Marin Co., although plants very rare or absent from Mendocino Co. Plants of Humboldt and northern Sonoma cos. generally intergrade in leaf and hair characters with Monardella villosa, and plants of Siskiyou Co. intergrade with Monardella odoratissima. If recognized taxonomically, plants of the Mount Tamalpais/Tiburon Peninsula region assignable to Monardella villosa subsp. neglecta (Greene) Epling; in comparison to more northern pls, these plants generally have internodes > 64 mm (vs shorter), bract length-to-width ratio of > 1.8 (vs < 1.8), generally > 1 flower cluster per main stem (vs generally 1 flower cluster per main stem), occasionally serrate leaves (vs entire leaves), and peduncle width > 1 mm (vs < 1 mm). Occasionally plants from Sonoma Co. combine flower cluster characters of some plants of Monardella villosa from San Luis Obispo Co. (those assignable to Monardella villosa subsp. subglabra; see discussion under Monardella villosa) and leaf characters of Monardella palmeri. Reports of Monardella purpurea from Santa Clara Co. (near Loma Prieta) and Santa Cruz Co. are unverified.
