Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A taxonomic revision is presented of the three taxa of <italic>Monstera</italic> (Araceae) recognized for Bahia State, Brazil:– <italic>M. adansonii</italic> subsp. <italic>blanchetii</italic> (stat. nov.), <italic>M. adansonii</italic> subsp. <italic>klotzschiana</italic> (stat. nov.) and <italic>M. praetermissa</italic>; a fourth taxon, not so far recorded from the state, <italic>M. adansonii</italic> subsp. <italic>laniata</italic> (stat. nov.), is distinguished from subsp. <italic>blanchetii</italic>. The two highly variable subspecies of <italic>Monstera adansonii</italic> were further investigated by morphometric study of herbarium specimens. These two taxa were distinguished using principal coordinates analysis (classical multidimensional scaling) and linear discriminant analysis; the most important diagnostic characters are stigma length and width, stigmatophore length, style apex size and leaf perforation number. Discrimination on leaf characters alone was over 90% successful – subsp. <italic>blanchetii</italic> differs most significantly from subsp. <italic>klotzschiana</italic> in higher values for perforation number and leaf base angle. Descriptions, illustrations, geographical and conservation status information and a key to the taxa are provided. Two neotypes are proposed (<italic>M. maximilianii</italic> Engl., <italic>M. klotzschiana</italic> Schott) and discussions of the typifications are provided. (© 2013 WILEY‐VCH Verlag GmbH & Co.
