87 Tonalá to Arriaga April 14 are just leaving out. Bonifacio collected two humilis in patches of totopoxta + understory in grassy savannah - not too good habitat apparently. Took photos 1-5 of Color Roll # 17 from the car - one showing hills where I collected plants. At 10.9 the river crosses the road where we parked the car last week and cooked our chachalacas - were heard here than . At 11.9 is the dry river where we collected humilis last week and where I was lost. This river looks big-tree riparia growth but has a wide sandy flood plain area where there are dense thickets of deciduous & evergreen trees and bushes . At 14.3 we stopped at another dry stream and found humilis abundant in dense stands of bushes, trees & deciduous vines along the sandy borders back from the stream bed. Guamuchil & ocotea were common, along with bushy totopoxta and several other dry small trees similar to those back from stream in the Study Area # 1. A pair of humilis found every 40 yds. or so. Nest high in BHA. Photos 6-10 Color Roll # 17 show this habitat.. I collected several of the dominant plants. The tree which is so common SE Tonalá is common here also. Drove into Arriaga and stayed at a hotel where we skinned our specimens.
