Selaginella fragillima

A spikemoss of the highlands of Minas Gerais in southeast Brazil, described by Silveira in 1898. The few records lie at 1144–1700 m, where summers are wet and winters dry, with cool nights. Its delicate growth suggests sheltered, moist spots among rocks or along streams in otherwise seasonally dry country.
