Duration: Annual Nativity: Native Lifeform: Forb/Herb General: Annual herb, 15-120 cm tall, from a slender taproot; stems erect, slender to robust, glabrous below the inflorescence. Leaves: Alternate and pinnately compound, 2-10 cm long, with 21-35 leaflets per leaf (leaves on smaller branchlets may have fewer leaflets); leaflets 3-12 mm long, oblong-to obovate, glabrous; lower leaf surface gland-dotted and lighter green than upper surface. Flowers: White to blue or pink-purple, in cylindric spikes, 2-8 cm long and about 1 cm wide, at branch tips; flowers about 5 mm long, with pea-flower morphology (papilionaceous), with a wide upper petal called the banner, two smaller lateral petals called the wings, and a boat-shaped lower petal called the keel which contains the style and stamens. Petals milky white to bluish-purple, almost blue, or rose-pink; sepals 5, abundantly silky-pilose, united at the base into a tube 3 mm long, this topped with 5 narrow teeth about 3 mm long. Fruits: Pod hairy near the top, small, and contained within the persistent hairy calyx; containing 1 or 2 seeds. Ecology: Found on roadsides, farm fields, along irrigation ditches, and other disturbed habitats, from 4,000-7,500 ft (1219-2286 m); flowers July-September. Distribution: WI to ND, south to TX, NM, AZ, and MEX; also in S. Amer. Notes: Look for this slender annual Dalea along roadsides. It is distinguished from other annual Dalea spp by this combination of traits: pinnately compound leaves with 6-20 pairs of leaflets; leaflets with rounded to truncate tips (not mucronate-tipped, or coming to a distnct, abrupt point); and flowers with hairy calyx tubes. The flower color is generally whitish with a tinge of blue or purple. Ethnobotany: Unknown Etymology: Dalea is named for Samuel Dale (1659-1739) an English physician and botanist; leporina means spotted, probably alluding to the gland-dotted leaves.

From Flora of Indiana (1940) by Charles C. Deam

On September 11, 1924, Mrs. Harry Bucklin of Brazil sent me a specimen which was collected at her summer home located in section 24 about 6 miles northeast of Brazil, Clay County. She wrote: "Frequent along the roadside and in an adjoining fallow field." I found the colony still persisting in 1934. No doubt introduced in seed of some kind since the farm is located on a little used road and not near a railroad.
