ROBISON'S MONARDELLA


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.

Monardella robisonii Epling ex Munz
NATIVE
Habit: Subshrub to shrub. Stem: 15--50 cm, erect, multi-branched mid-stem to tip, appearing +- gray, hairs long-spreading and short-erect or -reflexed, surface partially obscured. Leaf: 8--20 mm, 2--6 mm wide, lanceolate to narrowly ovate, entire, ash-gray or pale ash-gray. Inflorescence: +- cyme- to panicle-like; flower cluster (1)3--several per main stem, 10--25 mm wide; bracts 9--12 mm, 3--5 mm wide, narrowly ovate, scarious, pink-tinged or not. Flower: calyx 6--9 mm, lobes narrowly acute; corolla 9--11 mm, pale rose to pale blue.
Ecology: Desert scrub, pinyon/juniper woodland, among granite boulders; Elevation: 950--1350 m. Bioregional Distribution: s DMoj. Flowering Time: Jun--Sep Note: Intergrades with Monardella linoides subsp. linoides in western Little San Bernardino Mountains Plants in Sheephole Mtns have characteristics intermediate with those of Monardella mojavensis.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
