Monardella nana

Higher Taxonomy
Family: Lamiaceae (Labiatae)View DescriptionDichotomous Key

Common Name: MINT FAMILY
Habit: Annual to shrub [tree, vine], glabrous to hairy, generally aromatic. Stem: generally erect, generally 4-angled. Leaf: generally simple to deeply lobed, generally opposite, generally gland-dotted. Inflorescence: generally cymes, generally many in dense axillary clusters surrounding stem, generally separated by evident internodes or collectively crowded, spike- or panicle-like, occasionally head-like or raceme, 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, occasionally 0, lower lip generally 3-lobed; stamens generally 4, epipetalous, generally exserted, paired, pairs generally unequal, occasionally 2, staminodes 2 or 0; ovary superior, generally 4-lobed to base chambers 2, ovules 2 per chamber, style 1, generally arising from center at junction of lobes, stigmas generally 2. Fruit: generally 4 nutlets, generally ovoid to oblong, smooth.
Genera In Family: +- 230 genera, 7200 species: worldwide. Many cultivated for herbs, oils (Lavandula, lavender; Mentha, mint; Rosmarinus, rosemary; Thymus, thyme), some cultivated as ornamental (in California Cedronella, Leonotis, Monarda, Phlomis). Note: Moluccella laevis L., shell flower, historical waif in California. Satureja calamintha (L.) Scheele subsp. ascendens (Jordan) Briq. reported as alien but not naturalized. Salazaria moved to Scutellaria; California Hyptis moved to Condea, California Satureja moved to Clinopodium.

Genus: MonardellaView DescriptionDichotomous Key

Habit: Annual to shrub, +- gland-dotted, scented. Leaf: entire to serrate, margin flat or wavy; petioles 0 or present, often grading into blade. Inflorescence: flowers in compact clusters of >= 1 per main stem, these occasionally arrayed in panicles (rarely spikes); flowers 3--100 per cluster; bracts generally erect in a cup-like involucre or reflexed, reduced in size inward, leaf-like to membranous in texture, green or straw-colored to rose or purple, linear to ovate, acuminate to acute or obtuse. Flower: calyx 5-lobed; 4--25 mm; corolla white to purple or yellow to red, weakly bilateral, upper lip erect, 2-lobed, lower lip recurved, 3-lobed; stamens 4; style unequally 2-lobed.
Species In Genus: > 30 species: western North America. Etymology: (Latin: small Monarda) Note: Complex; study needed; many taxa intergrade; flower cluster width and bract orientation given for pressed specimens. Leaf length including petiole, if present. M. Brunell authored Monardella follettii (in part), Monardella odoratissima (in part), Monardella palmeri, Monardella purpurea, Monardella sheltonii (in part), Monardella stebbinsii, Monardella villosa (in part).

Monardella nana A. Gray
Habit: Subshrub, matted or tufted, rhizomed. Stem: 5--30 cm; hairs 0.5--2 mm, variable, recurved or spreading. Leaf: 5--30 mm (petiole 3--10 mm), 4--20 mm wide, narrowly ovate to round, entire, green to ash-gray, glabrous to appressed- or spreading-hairy, base +- truncate to strongly wedge-shaped (tapered). Inflorescence: flower cluster 10--35 mm wide; bracts 15--20 mm, generally ciliate; outer bracts like leaves or not; middle bracts white, generally rose- or purple-tinged. Flower: calyx (10)12--15 mm, 2--3 mm diam, hairs sparse to dense, generally > 1 mm, wavy, lobes 2.5--3.5 mm; corolla 15--30 mm, 6--15 mm diam, white to cream-yellow, occasionally rose-tinged, tube 15--25 mm, 0.5--2 mm diam at tip, cylindrical, short-hairy, lobes 4--10 mm, oblong; stamens slightly exserted, anthers < 1 mm.
Ecology: Montane chaparral, woodland, forest, dry desert-like slopes; Elevation: 800--2600 m. Bioregional Distribution: PR; Distribution Outside California: Baja California. Flowering Time: May--Aug Note: Previously named infraspecific taxa intergrade extensively; more study needed.
Synonyms: Monardella nana subsp. arida (H.M. Hall) Abrams; Monardella nana subsp. leptosiphon (Torr.) Abrams; Monardella nana subsp. tenuiflora (A. Gray) Abrams; Monardella macrantha var. pinetorum H.M. Hall
Unabridged Note: Extensive variation throughout range. Variable along elevational and environmental gradients from desert edge into conifer forest. Identification of most specimens to previously recognized infraspecific taxa is generally problematic. If infraspecific taxa in this complex warrant recognition, then current circumscriptions need revision.

Geographic subdivisions for Monardella nana:
Markers link to CCH specimen records. Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues. Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
