Reconsideration of Alsophila odonelliana (Cyatheaceae), an Andean tree fern. Brittonia 57: 228–236. 2005.—Two Andean tree fern species formerly united are hereby distinguished: Alsophila incana from Colombia, Ecuador, and Peru, and Alsophila odonelliana from southern Bolivia and northern Argentina.
