R.K Selander, 1954 58a "La Puerta" [=El Puerto], Veracruz May 28 The stands of oaks where nelsonii occurs are very limited in extent in this area, existing only at the top of the ridge which forms the summit. 200 feet below the store at the summit the vegetation is shrubby and unsuited for wrens. Below this the shrubby oak a cither temperate vegetation blends into the typical lower Sonoran cortex - mezquite - yucca forest of the Tehuacanon Valley. Much of the area along the ridge at the summit is being cleared for cultivation and in several more years all of the remaining good, dense stands of large oaks may be destroyed. As it is now I could find wrens only along rather steep slopes which haven't as yet been cleared. Lask said that collecting was much better than 10 years ago when he took specimens of Cyanolixea nana near the camp spot. I could not judge how far north and south this "cloud forest" extended but just over the summit west of camp the steep slope is covered with dry low vegetation unsuited for wrens. The front of large oaks is certain, well isolated both east and west. We left at 12:00 and drove to Mexico City. The town of Rio Frio is located in a grassy valley ringed with slopes of pine forest. After leaving the town the road climbs perhaps another 1000 feet
