Ribes erythiocarpum Coville & Leiberg, sp. iiov. 



Shnilj trailing upon the ground, devoid of prickles, the stems rooting 

 and giving rise to ascending branches commonly 10 to 20 cm. in height, 

 the herbage and inflorescence clothed with short glandular hairs; leaves 

 angulate-orbicular in outline, rugose, commonly 2 to 3.5 cm. in diameter, 

 on petioles nearly as long, 3 to 5-lobed, the sinuses extending one-half or 

 two-tliirds tlie way to the base, tlie lobes coarsely crenate and the crena- 

 tures unevenly but finely dentate-serrate; racemes erect, commonly 10 to 

 20-flowered, tlie bracts lierbaceous, lanceolate to obovate, commonly 2 to 

 4 mm. long, persistent ; flowers erect, contiguous, when expanded 6 to 8 

 mm. in diameter, on pedicels equaling the bracts ; ovary beset with short 

 glandular hairs ; calyx not produced into a tube, the spreading lobes 

 oblong, obtuse or broadly acute, yellow, minutely dotted with red, there- 

 fore appearing salmon-colored, sparingly and minutely pubescent without, 

 glabrous within ; petals broadly sixxtulate, glabrous, one-third to one-half 

 the length of the calyx lobes and similar in color; filaments glabrous; 

 style glabrous, 2-parted ; fruiting racemes erect or sometimes declined by 

 the weight of the berries ; fruit on erect pedicels, scarlet, subpyriform to 

 spherical, commonly 8 to 10 mm. in length, provided with sliort glandular 

 hairs, th(i flesh white or translucent, insipid. 



Type sjiecimen in the United States National Herbarium, collected 

 August 12, 1S9(), at an altitude of about 1,675 meters, in the canyon of Pole 

 Bridge Creek, about 10 kilometers south of Crater Lake, Cascade INIoun- 

 tains, Oregon, by Frederick V. Coville and John B. Leiberg. 



The plant appears from the structure of its flowers to he most 

 nearly related to the Ribes hixiflorum of Pursh and the Ribes 

 howellii of Greene {R. acerifoHum Howell), from hoth of which it 

 is at once distinguishahle hy its creeping hahit and its glandular 

 pubescence, in the latter of these characters and in its general 

 appearance closely resembling Pursh's Ribes viscosissimum. Its 

 herbage, however, possesses the rank odor of Ribes prostratum 

 and R. hudsonianum, quite distinct from the citronella-like smell 

 o^ viscosissimum. That species, too, has blue fruit and an elon- 

 gated calyx tube. Ribes erythrocarpum grows in abundance 

 about Crater Lake, in the forests of Tsugd pattoniawi, to an alti- 

 tude of at least 2,400 meters.
