New species of the genera Stenomesson and Eucharis (Amaryllidaceae) are described from Ecuador. Ste-nomesson 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 fl ower color and the fusion of the staminal corona to the perianth tube. It diff ers 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 diff ers by the narrower leaves and tepals; short, deeply cleft staminal corona; the long teeth on either side of the free fi laments; the narrowly subulate, incurved free fi laments; and the shorter style. Th e green mature fruit and campanulate fl oral morphology place it in Eucharis subg. Heterocharis.
