Mirta Arriaga, Roberto Gómez Cadret, María Montero


The herbarium of the Argentinian Museum of Natural Sciences (BA Herbarium) was the first official herbarium in this country. It was initiated in 1853 and at present holds 150,000 herbarium samples from different points of Argentina. From them about 100,000 correspond to vascular plants and 800 represent nomenclatural type specimens. The present contribution is the second part of the "BA Herbarium type specimens catalog" and presents information on 112 type specimens of the family Poaceae. The specimens are alphabetically ordered, and species name, author, original citation and date, type classification, and all label data are transcribed. Under observations, ecological data or additional notes written by the author of the description are given. Under notes, some considerations of our own, or the current synonymy are given. Type specimens are kept in special metal cabinets, separated from the general herbarium and documented with a copy of the original diagnosis and illustration. A database was developed with the program ACCESS 2000
