Subspecies
No subspecies.

Recent molecular-genetic research suggests that the Galapagos group consisting of present genus and Certhidea, Platyspiza and Geospiza, known collectively as "Darwin's finches", is allied to the tanagers (Thraupidae), being closest to Coereba, Tiaris and several Caribbean genera.

Similar Species
Differs from Large Tree-Finch (Geospiza psittacula) mainly in substantially smaller and less parrot-like bill, and from Small Tree-Finch (Geospiza parvula) in larger bill.
