This plant is common in the semiarid parts of Bahia, where it is known as palmadora or palmatoria. Johnston and Tryon describe it briefly without giving it a name in their Report of the Prickly-Pear Travelling Commission, 104. 1914.

Figure 250 represents joints of the type plant; figure 251 is from a photograph of the wild plant from which the above was taken.


Erect species, mostly tall, with terete, continuous, unjointed, usually densely spiny trunks, the ultimate branches spreading; or divaricate, flat, ^ ^ , ,

usually elongated, spiny or sometimes unarmed; flowers small, yellow, orange or red, or changing from yellow to red; fruit fleshy. We recognize seven species, all natives of the West Indies. The series represents the genus Consolea of Lemaire.
