(Figm'es 2 and 3 are drawn from Swedish specimens.) R. Cymbalaria Ptirsh var. alpina Hook. Found with the flowers fully developed, and showing the same habit as farther south, with long stolons above ground. The species is well equipped for propagation and widening of its range of occurrence, even though the individuals are very small and the flowers always single. R. pygmaeus Wahlenb. Numerous specimens were collected with flowers and young fruit; in spite of the small size of the plant, the shoot above ground measuring seldom more than 2 cm. in height, the vertical rhizome extends to a depth of about cm. and bears numerous slender, ramified roots. R. lapponicus L. Like Anemone Richardsonii and R. Pallasii, this species has a horizontally creeping rhizome, and the ramification is monopodial until the first flower appears. A young rhizome (Fig. I: 1) from a specimen collected on the south coast of Coronation gulf thus shows part of the rhizome (R.) bearing two green leaves (L^ and L^), while the terminal part of same rhizome (St.) is terminated by a free bud; secondary roots, long and slender, are developed beneath the first leaf (L^)..
