Stems (18-)30-50(-85) cm; base reddish, glabrous. Leaves: basal leaves 0-2 at anthesis; cauline leaves 3-7 at anthesis; petiole 1-8 cm. Leaf blade round to pentagonal, 1-4 × 1.5-6 cm, nearly glabrous; ultimate lobes 3-11, width 3-15 mm (basal), 1-10 mm (cauline). Inflorescences (8-)10-25(-47)-flowered, narrowly pyramidal; pedicel ± spreading, (0.5-)1.5-4(-6) cm, nearly glabrous; bracteoles 3-8(-18) mm from flowers, green, sometimes margins white, lanceolate to linear, 3-5(-8) mm, nearly glabrous. Flowers: sepals light to sky blue (becoming bluer upon drying), puberulent, lateral sepals reflexed, 11-16 × 5-7(-9) mm, spurs straight to gently upcurved, ascending 0-30° above horizontal, 10-15(-18) mm; lower petal blades elevated, ± exposing stamens, 5-8 mm, clefts 0.5-2.5 mm; hairs mostly centered on inner lobes near base of cleft, white. Fruits 8-21 mm, 2.2-3 times longer than wide, puberulent. Seeds: seed coat cells brick-shaped, cell margins undulate, surfaces roughened. 2n = 16.
Phenology: Flowering spring.
Habitat: Grassland, Atriplex scrub
Elevation: 30-600 m
Discussion
Of conservation concern.
Delphinium recurvatum has a very restricted distribution in the Central (especially San Joaquin) Valley. This species was probably much more common in the past; most of its habitat has been converted into irrigated croplands. Delphinium recurvatum grows in poorly drained, alkaline soils on valley floors.
Hybrids are known between Delphinium recurvatum and D. gypsophilum, D. hesperium, D. parryi, and D. variegatum. Delphinium recurvatum is most likely to be confused with D. gypsophilum or D. hesperium subsp. pallescens. Distinguishing features are found in discussions of those taxa.
