"By the time the Beagle left the Galapagos, Darwin had amassed a spectacular collection of Galapagos plants. It is fortunate that he took such trouble. Most popular narratives of Darwin and the Galapagos concentrate on the far more celebrated finches or the giant tortoises. Yet when he finally published On the Origin of Species almost 25 years later, Darwin made no mention of these creatures. In his discussion of the Galapagos, he dwelt almost exclusively on the islands’ plants."
