Whist looking around the Abha area I came across a dry sandy wadi with a number of Indigofera spinosa. This species has a native range from Egypt to Tanzania as well as the Arabian Peninsula. Indigofera is a large genus of over 750 species of flowering plants belonging to the pea family Fabaceae. They are mostly shrubs, though some are small trees or herbaceous perennials or annuals. Most have pinnate leaves. Racemes of flowers grow in the leaf axils, in hues of red, but there are a few white- and yellow-flowered species. The fruit is a legume pod of varying size and shape.
