Synonyms[2][3]

Leptocereus is a genus of cacti that are native to the Greater Antilles.[4] It has been placed in the tribe Leptocereeae[5] or in a broadly defined Echinocereeae.[6]

It is a very rare plant to encounter. The plants themselves are mostly sprawling shrubs, but can also form trees up to 30 feet or more in height. The stems are highly angled; with few large ribs which bear comfortably-spaced areoles that have spine clusters of about 10 spines or so. Some lose spine as they age. Often, the flowers are white or whitish-green and bear spines on raised areoles.[7]
