GC-MS Characterization of Ethanolic Extract from Croton wagneri Müll. Arg.

José González, Julio Pérez, Max Monan, Osvaldo Rodríguez
An ethanolic extract at 50% obtained by maceration process was characterized by GC-MS using a Shimadzu QP2010 spectrometer and the Silylation agent was N,O-bis (trimethylsilyl) trifluoroacetamide (BSTFA). The compounds were analyzed using GC/MS NIST21 and NIST107 libraries and having into account the results obtained after phytochemical screening and comparing the results with NISTDEMO Software. After 78 minutes of running 859 chemical components were identifie

Corrections in Recently Described Species of Ferns and Lycophytes from the Neotropics

Alexander Francisco Rojas-Alvarado
In recent papers on ferns and allied plants, several new species names were published invalidly or illegitimately, because they had been used previously or because their type specimens were designated ambiguously. The International Code of Nomenclature for algae, fungi, and plants (Shenzhen version) was revised to remedy these situations and to apply correct names for the new taxa. Finally, new names are proposed or the correct ty

Three New Species and New Records of Dennstaedtia Bernh. from Mesoamerica

Alexander Francisco Rojas-Alvarado, Federico Villalobos-Brenes
Navarrete & Ollgaard [1] indicated the presence of a “C” group within Dennstaedtia Bernh. that contains D. obtusifolia (Willd.) T. Moore, which is the type material of the genus Patania C. Presl and indicated that it could require taxonomic recognition. They also discussed the situation generated by other authors including D. cornuta (Kaulf.) Mett. and D. obtusifolia as synonyms for D. dissecta (Sw.) T. Moore a
