ROSA BLANDA, Ait.— Common everywhere along streams in the foothills. Dr. Smith; Median. Porter; Brandegee; Coulter.

ROSA ARKANSANA, Porter (n. sp.) Stem stout, erect, leafy, l° high, glabrous and glaucous, armed with weak, deciduous, bristly prickles; leaflets 9-11, ovate and oblong-ovate, 1' or more in length, acute or obtuse, glabrous, sharply serrate; midrib and long stipules somewhat prickly and minutely glandular; flowers numerous, terminal, corymbed, on peduncles about 1' long; fruit globose, smooth, glancous; calyx-segments ovate, reflexed in fruit, with terminal and sometimes lateral appendages, more or less glandular and tomentose pubescent on the margins; petals broadly obcordate or emarginate, longer than the calyx segments, rose-color; flowers 2' in diameter.— This rose may possibly be an extreme form of R. blanda, but it differs in so many points that I have ventured to describe it as new.— Banks of the Arkansas near Cañon City, Brandegee. Raton Mountains, Dr. Bell. Texas, Wright.

ROSA FRAXINIFOLIA. Bork. Resembles R. blanda. Flowers large, 3' in diameter; fruit larger, 6' to 8' in diameter; 2° to 3° high, growing solitary on dry ridges.— In the mountains, Hon. John Scott.

Note: ° = foot, ' = inch

CybeRose note: I seriously doubt that the hips of this R. fraxinifolia could be 6 to 8 inches in diameter.
