A leafless shrub. Branches excessively compressed, 3/8″–5/8″ broad, thin, with numerous parallel grooves, minutely pubescent when young, hoary, or silky; notches alternate, distant. Leaves unknown. Flowers sparingly produced, solitary or 2–3-flowered fascicles, very large, with the pedicels fully 1″ long, pedicels slender, silky. Calyx large, 5-toothed, acute, pubescent; corolla sharply curved upward, petals acute; stamens diadelphous; ovary shortly stipitate, glabrous; style long, curved, stigma capitate. Pod unknown.

This fine species, in all respects the largest of the genus, is allied to C. nana, Hook. f., in the structure of the flowers, but entirely lacks the rigidity of that species. It will be interesting to learn if it resembles its ally in the turgid pod.
The branches are very thin for so large a plant, the notches are more distant than in any other species, and in the young state carry a single triangular scale, exactly as in C. nana, but in old branches the single scale is replaced by an aggregated mass of shorter scales, sometimes attaining the size of a small pea. The upper part of the vexillum forms a right angle
with its base; the alæ are almost equal to the vexillum in length, but rather narrow; the carina is sharply curved, both segments being coherent for their entire length. The flowers appear to be of a lurid red colour similar to those of C. nana.
I am indebted to the Venerable Archdeacon W. L. Williams for specimens of this and other rarities; it affords me especial pleasure to associate his name with so fine a plant as a mark of appreciation of the unobtrusive services he has for many years rendered to botanical science in this colony.
