Fornica, Fraxinus oregona with occasional trees of Ouercus lobata and ©. chryso- 
lepıs. 
The eastern and western sides of Red Mountain are peculiar in the presence 
of groves of Cupressus Macnabiana. The underbrush consists of Corylus 
rostrata var. californıca, Calycanthus occidentalis, Rhus diversiloba, Rhamnus 
californıca, Rosa gymnocarpa, Gaultheria Shallon, Vaccinium ovatum, V. parvi- 
folium, Rubus vitifolius and in certain places Ceanothus integerrimus, C. incanus 
and C. velutınus. At Red Mountain grow Zilium pardalinum, Aguilegia trun- 
cata, Epipactis gigantea and a fern Pellaea densa. 
Chaparral Formation. This formation consists of athicket of low trees 
and shrubs. It is bushland or scrub, It coincides with dry stony ground 
and is composed of such shrubs as Adenostoma fasciculatum, Ceanothus cuneatus, 
Ouercus dumosa, Cercocarpus sp., Garrya Fremonti, Eriodictyon glutinosum 
(= E. calıfornicum). 
The grasses usually found in such localities are Melia californica, M. Har- 
Fordiü, Elymus multisetus, E. planifolius, E. glaucus, Bromus carınatus and oc- 
casionally Festuca ovina'). 
The chaparral formation covers millions of acres of the high slopes on 
the north sides of the mountains of the Coast Range and rolling hills. Here, 
as near Ukiah”), the slopes facing south are grassy with scattering trees of 
Ouercus Douglasii and Aesculus californica with many herbs in the spring. 
The composition of the chaparral on the higher mountain slopes as about Lake Clear?) in 
the heart of the Coast Range is similar to that already described. Species of Adenostoma, Cerco- 
carpus, Ceanothus and Arctostaphylos abound, There are besides clumps of Garrya Fremonti, 
scattered individuals of Ceanothus divergens, sg Be var. bullata and occasionally 
Rhamnus ilicifolia. Here too are Dicentra chrysantha, Linum californicum, L. EpEIgnlinnm, Galium 
Andrewsii, Hypericum coneinnum, Eriogonum dasyanthemum and Gnaphalium californicum. The 
ottle-stone, or obsidian nen Chorizanthe Clevelandi, Oxytheca hir, Seutellaria Bolanderi 
and Quereus Wislizeni. Opens in the chaparral are bright with Hypericum anagalloides, Silene 
californica, Eriogonum vimineum, Clarkia rhomboidea, Mentzelia Wh, Eriophyllum caespi- 
tosum, Gomphocarpus cordifolius, Phacelia ramosissima, Emmenanthe penduliflora, Antirrhinum 
virga, Pentstemon azureus, Mimulus Bolanderi and Verbena prostrata. 
4. Mountain Summit Formations. 
Several mountains are sufficiently high to show a flora somewhat like that 
of the Sierra Nevada Mountains in appearance. Such are the San Hedrin 
Mountains, Mount Hull, Snow Mountain (8,048 feet = 2453 m), Mount St. John, 
Mayacamas Mountains and Mount St. Helena (4,343 feet = 1324 m). 
Forest Formation. The trees of Snow Mountain‘) and the elevation to 
which they reach are as follows: Adies concolor (4,000—6,000 feet = 1220 
— 1830), A. nobilis (6,000 feet = 1525 m), Pinus sabiniana (3,800 feet), Pinus
