Coast Range Distriet. 609 
In the beds of streams grow Eriogonum virgatum, Mentzelia laevicaulis, Chrysopsis ore- 
gona, Senecio.eurycephalus, Nicotiana attenuata, Verbascum virgatum, Mimulus pilosa, Trichostema 
laxum and Argemone munita (= A. hispida). 
Forest Formation. The benches along the edges of the valleys support a growth 
of trees among which may be mentioned Quercus Douglasii, Pseudotsuga Douglasii, Quereus 
lobata, Arbutus Menziesii, Fraxinus oregona, Quereus californica and Negundo californieum with 
thickets of Rosa californica and such lianes as Clematis ligustieifolia and Vitis californiea. 
b) Santa Lucia Area. 
This comprises the coast range country south of San Francisco Bay and 
as far south as Point Concepcion. It too is characterized by the presence 
ofthe redwood, but in isolated groves one in the Santa Cruz Mountains 
and a smaller one in the Santa Lucia Mountains. 
ı. Sea Coast Formations. 
Marine Algal Formation. Out from the shore in the deeper water ot 
Monterey Bay’) occurs an association of seaweeds of gigantic size. Here are 
found Macrocystis pyrifera, Iridaca laminarioides and Nereocystis Lütkeana 
(Macrocystis Association). The tidal pools immediately along shore are charac- 
terized by Cladophora scopaeformis, Ulva latissima, Halosaccion hydrophora 
and species of Gelidium, Prionitis and Nitophyllum (Cladophora Shelf). "The 
algal shelf uncovered with the retreat of the tides is characterized by the pre- 
sence of Fucus fastigiatus, F. Harveyanus F. evanescens, Codium tomentosum 
and Halidrys osmundacea (at low tide mark). 
Coastal Bluff Formation. In the absence of detailed information on the 
flora of this formation in general it may be said that three trees are characteristic 
of the coastal-bluffs. Cupressus macrocarpa (see the next page Fig. 29) 
occupies a strip about two miles long and two hundred yards wide from cy- 
press Point to the shores of Carmel Bay, with a small grove on Point Lobos’). 
Pinus insignis (= P. radiata) is also restricted in its distribution being confined, 
to the country immediately adjacent to the Bay of Monterey where it forms 
a narrow forest a few miles long, back of the grove of Cupressus macrocarpa. 
Pinus Torreyana is found only on the border of the high bluff and on the 
sides of the ravines extending from it to the sea, north and south of Del Mar 
in San Diego County, where it stretches along the coast for a distance of 
nearly eight miles, but nowhere penetrates inland more than a mile and a half. 
A single grove of this tree also grows on the east end of Santa Rosa Island, 
off the California coast °).
