Carmichælia gracilis, n.sp.
A climbing or twining shrub with very slender twiggy branches 5–6 feet long, climbing among bushes. Branches glabrous or very minutely pubescent, striated, terete, naked and simple below, much branched above and leafy; branchlets extremely slender. Leaves numerous for the genus, trifoliate, shortly stalked. Leaflets broadly obcordate, ¼–½ inch long; the terminal one always the largest, undulated on the margins, sometimes obscurely serrate or crenate, bright green above, whitish below. Veins very finely reticulated. Flowers ¼–½ inch long in 2–8-flowered, loose, lateral, erect racemes. Pedicels extremely slender, straight, ⅓ inch long, covered with minute glandular pubescence, each with a very short, narrow-linear ciliated bract at its base. Calyx densely minutely pubescent. Teeth acuminate, ciliated, the two lower the smallest. Corolla white and purple. Standard broadly orbicular, longer than the wings. Keel deeply incurved. Stamens and style as in the genus. Ovary slightly silky. Pod very coriaceous, nearly half an inch long with a broad replum, wrinkled valves, and a curved awl-shaped beak ⅕ inch long. Seeds dark brown, mottled with white.
Hab.—Site of the city of Christchurch, formerly common but now extinct. My specimens were collected sixteen years ago. It is a very pretty plant when fresh, easily distinguished from the other species of the genus by its slender twining habit, trifoliate leaves, pubescent calyx and small bracts.
