Two new species of endemic Ecuadorean Amaryllidaceae (Asparagales, Amaryllidaceae, Amarylloideae, Eucharideae).

ABSTRACT: New species of the genera Stenomesson and Eucharis (Amaryllidaceae) are described from Ecuador. Stenomessonecuadorense is the second species of the genus reported from that country, and the only endemic one. It is related to Stenomessonminiatum and Stenomessoncampanulatum, both from Peru, with which it shares orange flower color and the fusion of the staminal corona to the perianth tube. It differs from Stenomessonminiatum by the non-urceolate perianth, from Stenomessoncampanulatum by its shorter stamens and longer perianth, and from both by its lower montane, cloud forest habitat. Eucharisruthiana, found in the vicinity of Zamora, is related to Eucharismoorei 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 Eucharissubg.Heterocharis.
