1. C. Enysii, T. Kirk in Trans. N.Z.I, xvi. (1883) 379, t. 30. Forming 

 dense patches lin.— 3in. above the surface of the soil. Root and lower branches 

 stout; secondary branches lin. long; branchlets fastigiate, iin.— fin. long, 

 -^va.—^-gm. broad, compressed, glabrous. Leaves only found on veiy young 

 plants, small, orbicular, emargiuate, shortly petiolate. Flowers solitary or in 

 3-5-flowered fascicles or racemes, red or pink. Pedicels slender. Calyx cam- 

 panulate ; teeth short, acute. Standard rather narrow, retiexed ; wings equalling 

 the keel. Ovules 2— 5. Pod y3_ijj ]ong j pedicels erect or recurved, shorter than 

 the pod, ovate-orbicular,, with a short recurved beak, at first turgid, compressed 

 when mature, 1- rarely 2-3-seeded. Seeds reniform, black. Replum incom- 

 plete. In dehiscence one valve becomes partially separated from the replum, 

 remaining attached near the apex, and both valves become contorted in such a 

 manner as to give the pod a curious deltoid appearance.
