Hooper, 1938 Jan. 6, of Canothus Arctostaphyhus, arbutus, Aderostema, occasional Roschhus and thymbellaria. Some shaded canyons were found to be quite moist at this time of year; seepage from soggy ground supplied the necessary moisture for rather luxuriant growths of ferns and other mesophytic plants. On the north side of Mt. Hamilton (away from Santa Clara Valley) vegeta- tion is more abundant. More Coulter pines were noted and, as well, a short-needled pine with a dark green foliage and a profile much like that of Pinus radiata; these latter pines were few. On this same side of the mountains was found a more abundant growth of Adenoxema+ and Canothus ; however, most exposed slopes were still grass covered. Along Arroyo Bajo and San Antonio Creek were occasional junipers - found chiefly on north and sloped slopes. The country in here is more today; places (ie., habitats) where I would expect to find many Peromyscus trees, P. californicus, Reognathus californicus,
