Samaipaticereus herrerae is a species of cactus native to Peru formerly considered a geographical variant of Samaipaticereus corroanus . [1]
Samaipaticereus herrerae is a heavily treelike cactus growing up to 4 meters tall. The pale green stems have 4 to 7 ribs, erect to arched, arcuate, and unsegmented. 5 to 17 orange to grey spines arise from brownish areoles 2-3mm in diameter.
The infundibuliform nocturnal flowers (5 cm long) only arise from subapical areoles. The flowers have white petals. Fruits are ovoid, 3 cm in length, and indistinctly ribbed. Seeds are larger than that of Samaipaticereus corroanus . [2]
Samaipaticereus herrerae was formerly considered a geographical form of Samaipaticereus corroanus. It was circumscribed due to subtle morphological differences of the two populations. [2]
