Further notes on a rare species of selaginella (pteridophyta - Selaginellaceae) from the cerrados of eastern bolivia

Abstract

Study of additional collections of Selaginella chiquitana M.Kessler, A.R.Sm. & M.Lehnert shows it to be conspecific with S. arroyoana M.Kessler & A.R.Sm. The apparent relationships of Selaginella arroyoana, its ecology and conservation status are discussed more fully. Scanning electron micrographs of spores and a map of its distribution are provided. © 2010 Trustees of the Royal Botanic Garden Edinburgh.
