Indigofera angustifolia flowers

The rose to pink flowers of Indigofera angustifolia grow in elongated racemes from leaf axils. The calyx is hairy as the outer corolla surfaces; sepal tips are narrowly pointed, awl-shaped.

The banner or upper petal of the corolla may be either rounded or pointed as the one in picture; the pair of narrow wing petals flanking the keel have central outward bulges, their tips rounded.

Flowering happens from late winter to midsummer (Bond and Goldblatt, 1984; Privett and Lutzeyer, 2010; JSTOR; iSpot).
