Discussion. Selaginella lechleri is known from Colombia and Peru ( Alston et al. 1981 ). Additionally, Smith (1995) cited it in Costa Rica, Panama, Venezuela, and Bo livia , while Cremers et al. (2007) and Mostacero (2008) also cited it in Venezuela, and Tropicos (2015a) registered it from Ecuador. I believe that specimens from Costa Rica and Panama are most likely Selaginella anceps (C. Presl) C. Presl, while those from Venezuela are best referred to another species. Selaginella lechleri is documented here to occur in the states of Acre and Amazonas, Brazil. It is characterized by its erect habit, lateral leaves with the basiscopic bases geniculate and usually glabrous, with the acroscopic margins short-ciliate along proximal ⅓ or dentate, otherwise sparsely denticulate to entire or serrate distally, and acuminate median leaves.
