Coast Range. District. 605 
A distinetive flora characterizes these plains composed of Quercus (Pasania) densiflora, Pinus 
muricata, P. contorta, Cupressus Goveniana, Castanopsis chrysophylla, Gaultheria shallon, Vacei- 
nium a Rhododendron californieum, Myrica californica, Ledum glandulosum, Arctostaphylos 
nummular nd such woody and herbaceous species as Polygala ealeraiet elianthemum 
scoparium, rain tenax, Hypericum concinnum, Gentiana Menziesii, G. oregona, Lilium 
maritimum, Panicum unciphyllum (= P. dichotomum), Agrostis Pringlei and Lotus euere 
og Formen: Perhaps owing to the impervious nature of the soil, sphagnum, or pea 
bogs have formed in the low hollows on the plains. Here grow Ledum glandulosum (the pre- 
vailing Be Blechnum spicant, Gaultheria shallon, Myrica californica, Veratrum fimbriatum, 
vıole sarmentosa (= V. sempervirens), Trientalis Bere kanlearneen californicum, Hosackia 
gracilis (= Bo formosissimus), Cornus canadensis, Hypericum ae loides, en tiana Menziesii, 
Drosera rotundifolia, Campanula linnaeifolia, Eulen aleutica, C. Bolanderi, C. crassiglumis, 
species of Agrostis, Juncus, Carex. The bog mosses are three species of een; S. cymbi- 
folium, S. mendocinum and S. subsecundum var. longifolium. 
Davy says with reference to the bluff flora.. “An analysis of the flora as 
above listed shows that its most characteristic feature does not consist so 
much in the presence of endemic species as in the commingling of the 
adjacent redwood and coast floras, with the addition of species commonly 
found in thin soils at comparatively high altitude, and of certain peculiarly 
boreal species, rarely if ever found at other points in the Coast ranges, and 
when met with elsewhere in the State, usually occurring at very much higher 
altitudes. The phenomenal feature is, therefore, the occurrence of several 
species belonging to high altitudes and latitudes, along a narrow coast mesa 
not more than 200 feet above sea level, and between the thirty-ninth and 
fortieth degree of north latitude”. 
he Kan to make this clearer, may be classified as follows: Plants of dry ri idges in 
the redwood strip are Cupressus Goveniana, Quercus densiflora, Polygala californica, Castanopsis 
chryso oh, Sireplistien m tenax, Gaultheria shallon, Vaccinium ovatum, Hypericum concinnum, 
Helianthemum scoparium, Rhododendron californieum, Myrica californica, Arctostaphylos nummu- 
laria and Pie species. 
The plants of moist, shady spots in the redwood strip are Viola sarmentosa and 
Trientalis ern

2. Redwood Formations. 
South of theChetco River a continuous strip of redwood (Seguoia semper- 
virens) begins increasing in width in the river valleys and lowlands from ı0 miles 
wide, in Del Norte County to ı8 to 2o miles, ending in Mendocino County. 
Scattered forests of the species are growing in sheltered spots, as far south
