On today’s show we learn about the Torrey Pine, a critically endangered evergreen conifer, native to the North American Pacific coast, with two populations in California, one near San Diego and one on Santa Rosa Island near Santa Barbara. Its scientific name is Pinus torreyana and it was first described in 1855.
