R.K. Selander, 1954 23 6 mi. NNW San Fernando, 3000 ft., Chiapas, Mexico April 26 Rode out on horse to a good patch of rain-cloud forest vegetation 6mi. NNW of town. Ruben Diaz calls the place "El Sosa"; [illegible] it is similar to the forest near San Pedro Muniz. Many tree forms, epiphytes, and vines - all evergreen. Noted tall liquid amber trees + many other species of tree including amate. Collected Syngonium for Monroe Birdsey. This forest occurs at the top of a hill at the apex of a valley which runs into the San Fernando Valley thusly. El Sosa Trail to El Sosa San Fern. to Santa Reta T6 xutla Ruben Diaz's home Following the trail from Ruben Diaz's place we passed thru some fairly good - but small - stands of subdeciduous forest before reaching the more humid and completely evergreen forest. The valley floors and many slopes have been farmed to bananas, sugar cane, and corn, but there are some thick rows of trees + dense understory of bushes and vines - mixed evergreen & deciduous -
