Acta Botanica Brasilica 28(3): 404-407. 2014. doi: 10.1590/0102-33062014abb3389 Typification of some species names in Elaphoglossum section Polytrichia (Dryopteridaceae) from Brazil Fernando Bittencourt Matos1,3 Received: 16 October, 2013. Accepted: 18 March, 2014 ABSTRACT The fern genus Elaphoglossum has received a great deal of attention in Brazil over the last two centuries. Nevertheless, many of the early names remain inadequately typified. In this paper, the nomenclature of some Brazilian species of Elaphoglossum sect. Polytrichia is discussed under the rules and recommendations of the International Code of No- menclature for algae, fungi, and plants. Lectotypes are designated for the following names: Acrostichum amplissimum Fée; A. apodum Kaulf. var. sprucei Baker; A. glaziovii Fée; A. lindbergii Mett. ex Kuhn; A. prestonii Baker; Elaphoglossum spannagelii Rosenst.; and Elaphoglossum ulei H. Christ. Most of these types were collected in Brazil during the 19th century and are now preserved in several European herbaria.

It is realized nowadays that such an assemblage results in a paraphyletic group containing species now placed in This study was largely based on the examination of distinct families (see Smith et al. 2006).
