cecio-polygamous and is often met with entirely sterile, while other adjacent areas are 

 immensely fruitful. It occurs abundantly in many localities, and affords large quanti- 

 ties of excellent fruit equal in value to our E. villosus. 



Riibus leucodennis, Dougl. This is very similar to our R. occidetitalis ; on dry hills 

 in the mountains; fruit somewhat larger and with smaller, less reticulate seeds than our 

 species, and very probably might l)y cultivation be made to surpass the improved black 

 cap raspberry of the eastern states. 



Rubus spectabilis, Pursh. This is the "Salmon-berry" of the inhabitants. Grows 

 on the l)anks of streams, generally in the hilly districts. The fruit is not produced 

 plentifully, Imt is rather largo and juicy, pleasant tasted and sought after to some extent 

 by the inhabitants. When fully ripe it is paie red and transparent. Sometimes it at- 

 tains 10 to 12 feet high, with stems two inches in diameter. 



Rubun JValkcmus, Mociuo. On hill-sides in open coniferous woods, forming vast 

 thickets, common and unimportant. 



Pyrm rivularis, Dougl. This is the Oregon Crab-Apple, with fruit in clusters no 

 larger than that of Viburmunpramfolum, which it resembles in shape, and when ripe, 

 in September, pale yellow. Not known to be of any economic use. The tree attains 15 

 to 20 feet and 2 to 4 inches in diameter, and abounds along streams rather sparingly. 



Pyriis sambueifolm, Cham. & Schlecht. Occurs rarely in the high Cascades. A 

 low bush. 



Oratmgus rimdnris, Xutt. A low, spreading, bushy-headed tree or shrub, spiny, 

 with smooth shining leaves. The fruit is abundant and black when mature, in August 

 and September. It abounds along streams and in lowlands, and is so abundant in places 

 as to be a serious impediment to the clearing of the best agricultural lands. 



Cratmgus Dou/jlasii, Lindl. A much rarer, larger tree; in the valleys; with larger, 

 incised, doubly serra|e, or sometimes lobed, leaves and strong spines 



Amelanchier alnifolia, Nutt. This is the Oregon representative of the eastern 

 "Service Berry"; not attaining to tree porportions so far as observed, fruiting abund- 

 antly on low bushes. The truit when ripe, in Augu.st, on the Cascades, is black and 

 highly prized by the mountain residents, ))eing very sweet and pleasant to the taste. 



Bibes MenziesiU Pursh. In the Cascade Mountains, rare. A low, spreading, bushy 



species, 3 feet high, remarkable for its large, densely prickly fruit, not available for any 



economic use. 



Ribes divancatum, Dougl. This is the Oregon representative of the eastern R. 



rotundifolium, much resembling it in mode of growth, in leaf and fruit, and affords the 



inhabitants a limited supply for tarts, etc. 



Ribes Keiomm, Doug). Wet Alpine woods; a low, spreading bush; fruit prickly and 

 of no value. 



Ribes sanguineum, Pursh. In the valleys and low hills ; a shrub 3 to 6 feet high, 

 highly ornamental in flower, bearing a profusion of large purple spikes in early spring. 

 The fruit is slightly prickly, rather small, and not used as an edible fruit by the 

 inhabitants. 



Ribes b rarteos II m, Dovigl. A remarkable species on the banks of shady streams in 

 the lower mountains, with immensely large leaves and fruiting racemes sometimes afoot 

 in length. Grows 6 to 8 feet high, with stems an inch in diameter. The peculiar currant 

 odor is exhaled heavily from the plant and its presence can be detected by this alone 

 several yards away. Fruit not edible. 



Ribes iiirreiu/i, Pursh. Sandy shores ot the Columbia at the Dalles. 



Ribes visr.osissiuiii, Pursh. Dry rocky hills of the Coiqmbia at the Dalles. Grows 

 in clumps, 4 to feet high. 



Pldladelphiis Lewisii, Pursh. A shrub of straggling growth, in open coniferous 

 woods, 6 to 8 feet high, somewhat ornamental in flower.
