This is the first in-depth coverage of the plants on islands in the Gulf of California found in between the coasts of Baja California and Sonora. The work is the culmination of decades of study by botanist Richard Felger and recent investigations by Benjamin Wilder, in collaboration with Sr. Humberto Romero-Morales, one of the most knowledgeable Seris concerning the region's flora. Their collective effort weaves together careful and accurate botanical science with the rich cultural and stunning physical setting of this island realm. The researchers surveyed, collected, and studied thousands of plants-seen here in meticulous illustrations and stunning colour photographs- providing the most precise species accounts of the islands ever made.
