interest. Only a partial examination of the specimens has been 

 made thus far, and a full report must be deferred, but an inter 

 esting species, apparently undescribed, is here presented to the 

 public. 



Ribes erythrocarpum Coville & Leiberg, sp. nov. 



Shrub 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-thirds the way to the base, the lobes coarsely crenate and the crena- 

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

 20-flowered, the bracts herbaceous, 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 spatulate, 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 short glandular 

 hairs, the flesh white or translucent, insipid. 



Type specimen in the United States National Herbarium, collected 

 August 12, 1896, at an altitude of about 1,675 meters, in the canyon of Pole 

 Bridge Creek, about 10 kilometers south of Crater Lake, Cascade Moun 

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



Th6 plant appears from the structure of its flowers to be most 

 nearly related to the Ribes laxiflorum of Pursh and the Ribes 

 hoivellii of Greene (R. acerifolium Howell), from both of which it 

 is at once distinguishable by its creeping habit 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 

 of 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 Tsuga pattoniana, to an alti 

 tude of at least 2,400 meters.
