A small species, never exceeding four to five inches in height, very variable in habit. Chai-acteristic specimens
are covered with appressed or spmading süky hahs. Leaves all from the root, half an inch long or so, entire or lobed
or divided into three segments to the base in large sjiecimens, which then resemble R. hirtus. Scapes many, slender,
.erect, spreading laterally, and cnrring when in fruit. Flowers and fr u it as in R. hirtus. In the variety y, the
whole plant is very fleshy, with scattered spreading hairs and but few short scapes, the flowers being actually sunk
among the leaves. It appears a very different species, but I have many specimens showing how the common form
becoming stunted and less hairy passes into the var. y.—P late V. Fig. 1, flower; 2, petal; 3, stamen ; 4 and 5,

ilexuose, rooting at the joints, where leaves and short stems are given off. Petioles very slender. 2 -4 inches long.

IÍAB. N o rth e rn Island, Colenso.
I am not aware whence Mr. Colenso procured this curious little plant : it is by far the most slender New
Zealand species of the genus. Stems, of which generally but few are given off from the root, slender, thread-like,
prostrate. Leaves chiefly radical, always on petioles 1 -4 inches long, the blade i inch, broad, more or less hairy,
entire or three-lobed. Stem-leaves on very short stalks, smaU. Flowers very minute, yellow, solitary at the axils
of the leaves, the upper one appearing terminal, the branch being hardly produced beyond it. Sepals and petals
of equal length. Carpels flattened, rough on the sides with small tubercles. This plant is also a native of various
parts of Australia.
Obs. The Ranunculus pinguis aud subseaposus, of Lord Auckland’s Group and Campbell’s Island, may both be
expected to be found on the lofty mountains of the IMiddle Island. A twelftli New Zealand species has been discovered
by Mr. Colenso on the Rualiine Mountains, but the specimens are too imperfect for description. The erect stems
have long hairs ; leaves radical, on long petioles, much divided into branching linear segments.
