and numerous other small-leaved, or thorny plants. Yet one of the lyciums, the “frutéa,” carries a huge load of the lichen, “orchilla”; and the ground about hour campsite is carpeted with an annual ice-plant, just now coming up - so wet that as we walk about it makes mud as it is ground into the soil! It is hard to define the place zonally. The cactus, and dense growths of arrowweed (pluchea) out along the “river” channel, the lyciums, etc., indicate Lower Sonoran; yet the “buck-eye”, artemisia californica (if it is that), Rhus, etc., might indicate Upper Sonoran. I have saved specimens of all the conspicuous bush plants, for identification. The birds are surely mixed: Cactus Woodpecker, Black-Tailed Gnatcatcher = Lower Sonoran; Calif. Thrasher, Spotted Towhee, Bewick Wren, Brown Towhee, etc. = Upper Sonoran. “San Diegan” applies close to the sub fauna; but a “San Quentin” phase of it might need to be recognized.
