Dipterostemon capitatus subsp. lacuna-vernalis
VERNAL POOL BLUE DICKS


Higher Taxonomy
Family: ThemidaceaeView DescriptionDichotomous Key
Common Name: BRODIAEA FAMILY
Habit: Perennial herb from corm, outer coat fibrous [membranous]; daughter corms formed at stem base above corm of previous year, cormlets formed at base of corms or on short stolons. 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: 13 genera, 70--80 species: western North America.

Genus: DipterostemonView DescriptionDichotomous Key

Habit: Cormlets sessile or on short stolons. Leaf: 2--5, generally keeled, entire, glabrous, occasionally withered by flowering. Inflorescence: few-flowered to dense; scape straight or +- curved; bracts +- papery; pedicels < to > flowers. Flower: perianth tube narrow-cylindric to short-bell-shaped, appendages 0; staminodes 0; stamens 6, unequal, 3 inner filaments with wing-like appendages, forming crown-like tube around anthers, anthers attached at base; style 1, stigma weakly 3-lobed.

Common Name: BLUE DICKS
Leaf: 2--3, 10--70 cm, +- keeled. Inflorescence: scape (4.5)8.5--50(100) cm; bracts wide-lanceolate. Flower: perianth blue, blue-purple, pink-purple, or white, tube (2)3--8(10) mm, lobes generally ascending; 3 stamens opposite outer perianth parts with filaments (1)1.8--3.8(4) mm, anthers (1)1.7--3.1(4) mm, appendages 0; 3 stamens opposite inner perianth lobes with filaments (0.5)1--3(3.7) mm, anthers (2.4)2.9--5(6.2) mm, appendages (3)4--8(9) mm, erect, curved outward at tip, white; ovary (2)2.9--5.3(6.1) mm, style (2.5)3.2--8.5(9.5) mm.
Note: Morphologically and geographically distinct population groups indicate that additional subspecies warrant recognition; relationship between morphology and ploidy level needs study.
Dipterostemon capitatus subsp. lacuna-vernalis (L.W. Lenz) R.E. Preston
NATIVE
Habit: Cormlets 0 to few. Inflorescence: scape 6--20(23) cm; pedicels < 4.5 mm, bracts 6--13 mm; flowers 1--3.

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.
