Blochman, of Santa Maria, has recently obtained this plant on the Cuyama or Santa Maria River, "growing right on the river looking across into San Luis Obispo County." It has not yet been reported nearly so far north. SIERRA NEVADA PLANTS IN THE COAST RANGE. BY KATHARINE BRANDEGEE. The great valley of California is a basin or plain irregularly elliptical in shape and about five hundred miles in length by one hundred in breadth. It is rimmed all around with mountains, the only opening being that from which all the waters of the basin escape to the sea. The northern half of the valley, drained by the Sacramento and its tributaries, is called the Sacramento Valley; the southern half, drained by the river of that name, is called the Valley of the San Joaquin. The slope of the land is to the centre, where the two rivers meet and pour their mingled waters into the Bay of San Francisco. The rim of the valley is highest where the Sierra Nevada makes its eastern wall, even the Truckee Pass, where the Central Pacific Railroad crosses it, being over seven thousand feet in altitude. The southern wall, formed by the Tehachapi Range, is nearly four thousand feet in its lowest passes; the northern, formed by the Shasta Range is but little less, and the western, though lower, is double, with a long valley or series of valleys intervening, the inner, at least in the northern half, having many peaks of considerable altitude, Yolo Bolo being over eight thousand feet, Sanhedrim, Hull and Snow Mountain between six and seven thousand. Seeds transported by whatever agency must find suitable conditions or they will not thrive, and to this fact, of course, we owe the diversity of flora still existing. The broad hot valley of California offers no suitable home for the plants of the Sierra and they cannot cross it. The valley plants cannot endure the cold of the mountains, and if they flourish for a season even their seeds succumb to the winter frosts. It is perhaps from a consideration of the barrier interposed by this valley that the flora of the Sierra Nevada has been considered to be so different from that of the Coast Range that surprise is often expressed at the finding of additional species common to both. It is, however, easily understood that plants may follow the valley wall in any direction and for a distance limited only by comparative height and consequent degree of heat. The localities of plants should be observed and recorded at |
