Sophora chrysophylla, known as Māmane in Hawaiian, is a species of flowering plant in the pea and bean family, Fabaceae, that is endemic to Hawaii. It is highly polymorphic, growing as a shrub or tree, and able to reach a height of 15 m (49 ft) in tree form. Yellow flowers are produced in winter and spring.
S. chrysophylla has ridged golden brown branches. The tree has pinnately compound leaves with 6 to 10 pairs of leaflets. Each leaflet is 0.7 to 5 cm (0.28 to 1.97 in) long and 0.3 to 2.3 cm (0.12 to 0.91 in) wide. Leaves are smooth, or with gray or yellow hairs on the underside. The specific name is derived from the Greek words χρυσός (chrysós), meaning "gold," and φυλλον (phyllos), meaning "leaf." Flowers are found at the bases of leaves or the ends of branches in clusters - that is, they occur in axillary or terminal racemes. The corolla is yellow. The petal size ranges from 11.5 to 21 mm (0.45 to 0.83 in) long, and 8 to 20 mm (0.31 to 0.79 in) wide.
The tree blooms in winter and spring. The height of the flowering season is in mid-spring. Māmane wood is dense, hard and durable. Seedpods are persistent, and remain on the tree for most of the year. They are twisted, brown to brownish-gray, have four wings and are 2 to 16 cm (0.79 to 6.30 in) long and usually 1.5 cm (0.59 in) wide. Seedpods are tightly constricted around the yellow-orange or brown to grayish-black seeds, which are 6.35 mm (0.250 in) long. Untreated, the seeds have germination rates of less than 5%. The tree is perennial and highly polymorphic.
