distribution
Sedum morganianum se conoce de la región centro del estado de Veracruz, de dos cañadas
profundas que corren en dirección O-E, la barranca de Mayatla y la de Ixcacotitla,
pertenecientes al municipio de Tenampa. Crece sobre paredes verticales de arenisca
conglomerada del Cuaternario (Anónimo, 2002a) de muy difícil acceso, en exposición N y S,
en un reducido intervalo altitudinal que va de los 600 a los 700 m, por lo que se considera un
endemismo estrecho. La población es numerosa, se observan cientos de individuos en los
cantiles.
