Dieter H. Wilken, except as specifed

Annual, perennial herb, shrub, glabrous to hairy, generally aromatic
Stems generally erect, generally 4-angled
Leaves generally simple to deeply lobed, opposite, generally gland-dotted
Inflorescence: cyme, generally clustered around stem, head-like, separated by evident internodes (terminal in Monardella ) or collectively crowded, spike-like to panicle-like (sometimes raceme or flowers 2–12); subtended by leaves or bracts; flowers sessile or pedicelled
Flower generally bisexual; calyx generally 5-lobed, radial to bilateral; corolla generally bilateral, 1–2-lipped, upper lip entire or 2-lobed, ± flat to hood-like, sometimes 0, lower lip generally 3-lobed; stamens generally 4, generally exserted, paired, pairs unequal, sometimes 2, staminodes 2 or 0; ovary superior, generally 4-lobed to base, chambers 2, ovules 2 per chamber, style 1, arising from center at junction of lobes, stigmas generally 2
Fruit: nutlets 4, generally ovoid to oblong, smooth
Genera in family: ± 200 genera, 5500 species: worldwide. Many cultivated for herbs, oils (Lavandula , lavender; Mentha , mint; Ocimum , basil; Rosmarinus , rosemary; Thymus , thyme), some cultivated as ornamental (in CA Cedronella , Leonotis , Phlomis )

James D. Jokerst

Annual, hairy or not, gland-dotted, aromatic
Stem decumbent to erect, branched or not
Leaf linear to round, entire to toothed, bristly-ciliate, short-petioled
Inflorescence: clusters, head-like or interrupted, terminal and axillary, or flowers solitary in axils; bracts 2 or more, bristly-ciliate
Flower: calyx 2-lipped, lobes 5, deep, glabrous to coarse-hairy; corolla 2-lipped, lavender, purple, or white, raised area on lower lip sometimes spotted; stamens 2–4, upper 2 sometimes sterile and vestigial or 0; style hairy below stigma lobes
Fruit hairy
Species in genus: 7 species: CA (generally CA-FP); OR, Baja CA
Etymology: (Greek: bearded style)
Reference: [Howell 1931 Proc Cal Acad Sci 20(3):105–128]
Fl generally Mar–Jun; Jul in some high-elevation P. douglasii; Jun–Aug in P. floribunda (MP).


P. douglasii Benth.

Plant robust, < 45 cm
Stem erect
Inflorescence 10–30 mm wide
Flower: calyx tube 2–4 mm, upper lobes 2–5 mm, tips acute, lower lobes 3–8 mm, 0.75–2.5 X tube, tips lanceolate to acuminate; corolla 9–20 mm, lavender, hairy, raised area on lower lip often yellow-spotted; style hairy 2–6 mm below stigma lobes
Fruit 1–2 mm
Ecology: Vernal pools, swales
Elevation: < 900 m.
Bioregional distribution: Outer North Coast Ranges, Inner North Coast Ranges, Sierra Nevada Foothills, Great Central Valley, Central Western California.Highly variable; most distinct variant is subsp. parviflora (Benth.) J.T. Howell, Douglas' pogogyne (calyx lobes 0.75–1.5 X tube; corolla 11–15 mm). Tall plants with acute calyx lobes in c&s SNF and low, branched plants of coastal bluffs in San Luis Obispo Co. may warrant recognition. Further study needed
Horticultural information: SUN, WET (winter only): 7, 8, 9, 14, 15, 16, 17.
