Brodiaea coronaria

Higher Taxonomy
Family: ThemidaceaeView DescriptionDichotomous Key
Habit: Perennial herb from corm, outer coat fibrous [membranous]. Leaf: basal, 1--10, linear to narrow-lanceolate. Inflorescence: scapose, generally umbel-like; scape erect, generally 1(2), cylindric, generally rigid, occasionally wavy to twining; flower bracts 2--4[10], not enclosing flower buds. Flower: perianth parts 6 in 2 petal-like whorls, free or +- fused below into tube; staminodes 0 or 3; stamens 3 or 6, free or fused to perianth, occasionally appendaged; ovary superior, chambers 3, ovules 2--several per chamber. Fruit: capsule, loculicidal.
Genera In Family: 10--11 genera, 60--70 species: western North America.

Genus: BrodiaeaView DescriptionDichotomous Key

Habit: Daughter corms often present. Leaf: generally 1--6, linear, generally crescent-shaped in ×-section, glabrous, entire, often withered at flower. Inflorescence: open; scape 2--70 cm, generally slender, generally straight, cylindric; bracts scarious; pedicels generally > flowers, generally < 13 cm. Flower: perianth tube bell- to funnel-shaped, green-white, lobes erect to spreading, violet to lavender, occasionally pink, midribs purple or green; staminodes (0)3, generally +- erect, opposite outer lobes, white to violet or lavender, lateral margins flat, incurved, or inrolled; stamens 3, equal, fused to perianth, opposite inner lobes, filaments occasionally winged or appendaged, free or fused basally to staminodes, generally not forming crown-like tube, anthers attached at base, appressed to style, abaxially papillate; style 1, stigma lobes 3, spreading and recurved. Fruit: sessile, ovoid. Seed: oblong, black, lined, angles ridged.
Species In Genus: +- 18 species: mostly endemic to California. Etymology: (James Brodie, Scottish botanist, 1744--1824) Note: Several undescribed taxa, hybrids under study. Brodiaea matsonii R.E. Preston described from Shasta Co., 2010.

Brodiaea coronaria (Salisb.) Engl.
Inflorescence: scape 5--25 cm; pedicel <= 7 cm. Flower: perianth 23--37.5 mm, tube 8.5--13.5 mm, cylindric, lobes 14--25 mm, violet, ascending, tips recurved, outer 3.5--5.5 mm wide, inner 5--8 mm wide; staminodes leaning toward but not appressed to stamens, 7.5--12 mm, generally white, flat or incurved below tip, tips obtuse; filaments 3--6 mm, anthers 4.5--7 mm; ovary 6--10 mm, style 6.5--11 mm. Chromosomes: n=12,24,42.
Ecology: Vernal pools, grassland; Elevation: 30--760 m. Bioregional Distribution: CaRF, n SNF, ScV; Distribution Outside California: to British Columbia. Flowering Time: Apr--Jun
Synonyms: Brodiaea coronaria subsp. coronaria
Unabridged Note: Brodiaea coronaria subsp. coronaria has been misapplied to plants with tightly inrolled staminodes that are appressed to the stamens. At least 2 such groups are morphologically, ecologically distinguishable, one in montane meadows in KR, CaR, MP, southern Oregon, the other in grassland in ScV, northern SnJV. In addition, California plants morphologically similar to Brodiaea coronaria from the Pacific Northwest differ in chromosome number and may represent separate lineages of hybrid origin. Study needed.

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.
