TAMAYO'S BLACKBERRY BUSH, NORTHERN ECUADOR. ■„... 
(Rubus adenotrichos Schlecht., S. P. I. No. 54279.) 
This species is the largest grower of all those which have been introduced from the Andean 
region. It is also notable for its productivity. The fruits are in terminal clusters some- 
times 2 feet long, each cluster containing as many as several hundred berries. The latter 
are much like the cultivated blackberries of the North in size, color, and flavor. Since the 
species grows in Ecuador at elevations of 10,000 to 12,000 feet, it may prove sufficiently 
hardy for cultivation in the Pacific Northwest, California, and the extreme South. (Photo-
