Neltuma odorata honey mesquite

Western honey mesquite at Carnegie Institute. Sairus Patel, 12 Jan 2019

A small, often crookedly branched tree with finely divided foliage, slender paired thorns, and dense, cylindrical racemes of tiny yellow flowers, followed by flat pods. A wondrously gnarled specimen fairly writhes along the ground at the former Carnegie Institution grounds, behind the Keck Laboratories. A girthy specimen rises from a sunken bed midway along the south side of Huang Engineering Center; from South Service Road, you look down on it.
