Coming to the extreme point, which runs out into a very narrow 
ridge, with precipitous sides, we find ourselves again in a situa- 
tion fully exposed to the winds, and also to clouds of fine spray 
driven up from the waves breaking on the rocks below, and again 
everything is excessively dwarfed. Achillea millefolium is a 
hand-breadth in height, while the dense growth of Pestuca ruhra 
is scarcely taller. Castilleia miniata, Statice armeria, Bpilohium 
franciscanum, Brig er on glaucus, Senecio bolanderi, and many 
others partake of the same character. 
The faces of the isolated crags, too steep, hard and exposed for 
the accumulation of sufficient soil to support ordinary vegetation, 
bear patches here and there of Sedum spathulifolium, and else- 
where are thickly starred with another and very remarkable 
Stonecrop, Dudleya farinosa. Many of the plants, especially 
those growing under the hardest conditions, appear quite destitute 
of the dense glaucus bloom to which the species owes its specific 
name. 
Along the south side of the promontory the conditions are 
somewhat less severe. On the extreme margin, almost over- 
hanging the precipitous descent to the sea, is a fine flourishing 
colony of M esembryanthemum acquilaterale, a strange plant, with 
fleshy leaves that are triangular in cross section, and handsome 
rose-colored flowers. Here too is an abundance of Crowberry 
(Bmpetrum nigrum) with long, prostrate, heath-like branches 
creeping over and almost smothering the low huckleberry bushes. 
Alpine Timothy (Phleum alpinum) and a small Mariposa Lily, 
Calochortus maweanus are not uncommon. 
Following the coast line a little farther to the east and south, 
we find the land sloping down a little, giving sufficient protection 
from the north wind to permit small Spruce and Pine trees to 
maintain themselves. As we recede from the coast line they 
grow taller and pass into the ordinary coast forest. The vegeta- 
tion accompanying them also assumes the usual character. 
While ecologically there is no more interesting place on the 
Oregon coast than Cape Blanco, it is scarcely less interesting 
from the standpoint of plant distribution. Thus Baeria macrantha, 
here found in remarkable abundance, is not known to occur else- 
where in the state. Lilium kelleyanum is extremely rare. Sanicula 
arctopoides is known from but one or two other Oregon localities. 
M esembryanthemum aequilaterale is a waif from the southward, 
not hitherto known from far north of San Francisco Bay. A 
Cirsium and an Agoseris, not yet determined specifically, are
