78 MADRONO [Vol. 1, 



been reported from the North Coast Ranges, but thus far only on 

 the basis of mistaken determination. 



In the lower part of Mill Creek Canon, San Bernardino Mts., I 

 measured in 1913 an individual 22 feet high with its short trunk 1 

 foot 1 inch in diameter. In September, 1920, I measured the large 

 individual which stands on the trail up the ridge backbone from 

 Donner Canon to Cold Spring below the saddle of Mt. Diablo. 

 It is 18 feet high, 24 feet broad across the crown, the trunk 21 inches 

 in diameter at 4 inches above the ground. This is a remarkable 

 tree.

2. A. viscida Parry. This species forms a broad band in the 

 Sierra Nevada foothills from Shasta Co. to Tulare Co., but with 

 a break in the band between the Stanislaus and Kings rivers, 

 which is occupied by the closely allied A. mariposa Dudley. This 

 interruption in the distribution can now only be stated broadly and 

 its exact limits and the nature of it will eventually be more definitely 

 defined. This species is however the most characteristic and wide- 

 spread member of the genus in the Sierra foothills and is now re- 

 ported from the inner North Coast Ranges. Its deep-red small 

 berries are either viscid or not viscid in a given locality and indeed 

 viscid and non-viscid berries may sometimes be found on a single 

 shrub. It forms extensive exclusive or nearly exclusive colonies, the 

 individuals of which are often densely massed.
