Barrios D., González-Torres L. R., Arias S., Majure L. C., Phylogeny and taxonomy of the Antillean endemic genus Leptocereus (Cactaceae) inferred from chloroplast markers and morphological evidence, Plant Systematics and Evolution, 2020, 306:63, doi: 10.1007/s00606-020-01693-5
Analysis of five plastid DNA markers and 39 morphological characters supporting inclusion of Dendrocereus in Leptocereus. Distinguishes a Cuban lineage, former Dendrocereus, and Hispaniolan and Puerto Rican taxa. Describes species morphology and variation, with limited resolution within the Cuban lineage. Historical species concepts were compared with current POWO.
