The maximum and the minimum: two new species of Tovomita Aubl. (Clusiaceae) from the Guiana Shield with an unusual number of stamens
Résumé
Two new species of Tovomita Aubl. (Clusiaceae) from the Guiana Shield are described and illustrated. Tovomita maxima Molino & J.Engel, sp. nov., known from French Guiana, Guyana and Brazil, stands out by its large size (up to 30 m high), large leaves with eucamptodromous venation, calyptrate bracteoles and an unusual variation in the number of stamens (74-145). Tovomita saulensis J.Engel & Molino, sp. nov., probably endemic to central French Guiana, is an understory tree with small leaves with brochidodromous venation and flowers with few stamens (9-15). Illustrations, descriptions, photographs in vivo, a preliminary conservation status, distribution map and comments on the morphology of related species are provided.
