Subspecies
No subspecies.
Recent molecular-genetic research suggests that the Galapagos group consisting of present genus and Certhidea, Platyspiza and Camarhynchus, known collectively as "Darwin's finches", is allied to the tanagers (Thraupidae), being closest to Coereba, Tiaris and several Caribbean genera. Present species hybridizes rarely with Espanola Cactus-finch (Geospiza conirostris) on Genovesa; on Santa Cruz, large-scale hybridization with Medium Ground-finch (Geospiza fortis) thought to have occurred.
