VL - 27 ER - TY - JOUR T1 - A new species and new combinations of Neotropical Cinnamomum JF - Novon Y1 - 2019 DO - 10.3417/2019346 A1 - van der Werff, Henk SP - 137 EP - 139 KW - Aiouea KW - Cinnamomum KW - Ecuador KW - Lauraceae KW - new species AB -

A new species of Cinnamomum Schaeff. from the Pacific coast of Ecuador is described and discussed. Cinnamomum latifolium van der Werff is distinctive for its broad triplinerved leaves with canaliculate petioles, densely pubescent young twigs, and 2-locular inner stamens. In addition, six species recently described in Aiouea Aubl. should, in this author’s opinion, be placed within Cinnamomum. The new combinations C.ampullaceum (Lorea-Hern.) van der Werff, C. hirsutum (Lorea-Hern.) van der Werff, C. paratriplinerve (Lorea-Hern.) van der Werff, C. pseudoglaziovii (Lorea-Hern.) van der Werff, C. rubrinervium (Lorea-Hern.) van derWerff, and C. uninervium (Lorea-Hern.) van der Werff are accordingly published. The author citation of the recently transferred C. baitelloanum van der Werff & P.L.R. Moraes to Aiouea is rejected.
