Ipomoea barbatisepala, commonly known as canyon morning glory,[1] is a species of morning glory. It is native to the Southwestern United States, where it has been found in New Mexico and Arizona;[2] in these regions, its native range overlaps with the non-native range of the closely related Ipomoea hederacea.[3] It is also found in the west of Mexico.[4]
The leaves are glabrous and deeply lobed, alternating on the stem.[5] The flowers are blue or rarely white with a yellow center,[5][6] usually appearing on the plant from July to December.[2] The fruit is a capsule containing several dark seeds. The plant can be distinguished from the similar Ipomoea hederacea and Ipomoea cardiophylla by the leaf shape; while I. cardiophylla has heart-shaped leaves[7] and I. hederacea has three-pointed leaves,[8] I. barbatisepala has multi-lobed leaves.[5]

Se distribuye en el sur y suroeste de Estados Unidos, así como en el norte del territorio mexicano. Por su hábito ruderal se encuentra ocasionalmente más al sur en México en los estados de Sonora, Michoacán y Oaxaca. Se colectó hace más de 20 años en la región de la Depresión del Balsas, sin haberse registrado nuevamente.[2][1]
Es una especie de comportamiento ruderal, que en el estado de Michoacán se colectó aproximadamente a 300 m de altitud en zonas agrícolas y en las orillas de los caminos.[2]
No se encuentra bajo ningún estatus de protección.
