Caltha dioneaefolia is a dwarf perennial herb, of the Buttercup Family (Ranunculaceae) with apparently seated pale yellow flowers with about seven stamens and two to three free carpels and leaves that are reminiscent of those of the Venus flytrap, but very small and with leaflike appendages on the leaf. It occurs in the southern Andes of Chile and Argentina, including on Tierra del Fuego and Hermite Island.
Description
Caltha dioneaefolia often grows in dense clusters over considerable areas, with thick
actinomorphic solitary flowers of about 1 cm across have five spreading, egg-shaped, yellow sepals, with about nine parallel veins on a short peduncle of about 1⁄2–1 cm, making it appear seated in the hart of the rosette of leaves. There are usually seven stamens. The two or three ovaries each contain two to five ovules. There are forty eight chromosomes (2n=48).[1][2][3][4]
Distribution and ecology
The species occurs in the Southern Andes. Bogs near the Strait of Magellan are densely coated by patches of C. dioneaefolia, Gaimardia and Astelia, that grow in between Sphagnum and other mosses.[5]
