Abstract

New species of the genera Stenomesson and Eucharis (Amaryllidaceae) are described from Ecuador. Stenomesson ecuadorense is the second species of the genus reported from that country, and the only endemic one. It is related to S. miniatum and S. campanulatum, both from Peru, with which it shares orange flower color and the fusion of the staminal corona to the perianth tube. It differs from S. miniatum by the non-urceolate perianth, from S. campanulatum by its shorter stamens and longer perianth, and from both by its lower montane, cloud forest habitat. Eucharis ruthiana, found in the vicinity of Zamora, is related to E. moorei from which it differs by the narrower leaves and tepals; short, deeply cleft staminal corona; the long teeth on either side of the free filaments; the narrowly subulate, incurved free filaments; and the shorter style. The green mature fruit and campanulate floral morphology place it in Eucharis subg. Heterocharis.
