Dr. Zweifel 1953 Journal En route, to Adjuntas camp to Mazatlan. July 11 frequently deposit parts of themselves on it. For much of the way, heavy rain fell and clouds enveloped the road, making it necessary to drive with the lights on. 16 miles by road past La Ciudad (in Sinaloa?) I found a small Crataegus lapidus under a rock by the roadside. This is at the foot of a cliff in pine-oak forest, elevation 7600' Camp was made at an elevation of 6700' just past the "town" of Revolcaderos. Logging has opened up the pine-oak forest so that the individual trees stand about 40' apart. Bromeliads are abundant, and there is a lush undergrowth of grass, ferns, and many other plants. Agaves are abundant on rocky outcrops. At least two kinds of pine are present here, one being the peculiar "weeping pine". July 12 Continued on to Mazatlan. A stop 33.6 road miles past La Ciudad, 6400', yielded Bana sp?, Scleronymus (ganon?) and an Anolis. Logged pine-oak-madrone. A DOR Crataegus lapidus was found just a mile down the road, and another three miles down. Neither was in condition to be saved. At 50 road miles past La Ciudad we stopped at a stream and collected several Bana. A Scleronymus, possibly S. bulleri, was also seen here. The Bana may represent a new species related to B. sierramadreensis
