while it is less stout than that of R. sinclairii, from which it is further 
distinguished by its singular habit. 
Occasionally the leaves are reduced to three linear segments. 
Ranunculus enysü. 
Glabrous in all its parts. Leaves all radical, on long slender petioles, 
9'-6" long, 3—5-foliate, leaflets on slender pedicels, tripartite or nearly 
simple, segments cuneate, trilobate, toothed, teeth acute, margins thickened. 
Scapes 8-5, naked, simple, 1-flowered, 5’-12” long, or rarely with a solitary 
branch springing from the axil of a reduced leaf. Flower 3” in diameter, 
sepals 5, broadly ovate acute. Petals 5-10, broadly obovate. Achenes small, 
in dense globose heads, glabrous, ovate, with a short slender curved beak ; 
testa minutely reticulate. 
Hab.—South Island; Trelissick, Canterbury, 2-3000 feet—J. D. Enys. 
Very different in appearance from any other New Zealand species, 
although in some respects it approaches the typical form of R. lappaceus, 
Sm., the styles, however, are never recurved, and the carpels are not 
keeled, as in that species; the heads are more truly globose, and, with the 
glabrous highly-divided leaves, afford subordinate distinctive characters of 
some importance. The rounded carpels distinguish it from R. plebeius, Br., 
and the minute curved styles from R. geraniifolius, Hook. f. 
Lecummosa. 
Carmichelia williamsi. 
A leafless shrub. Branches excessively compressed, $'-$" 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, pubes- 
cent; 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
