form, with brown, irregular, thornless branches, rounded leaves 

 10-15 mm. in diameter, and small flowers with refiexed calyx - 

 lobes. The leaves correspond much better to the name rotundi- 

 folium than do those of the more common form referred to this 

 species. The plant seems to approach B. curvata. 



Western Massachusetts and New York, southward to North 

 Carolina along the Alleghanies. 



This appears to be unknown in cultivation, owing, no doubt, 

 to the small size of its fruit. 



17. R. LEPTANTHUM, Gray. (Fig. 89.) 



Sturdy, much branched, rigid shrub, 1-4 feet (3-12 decimeters) 

 high, with grayish bark, and no prickles, thorns long, slender, 

 single or triple, like the bark in color; leaves roundish, very 

 small, 3^-% inch (6-15 mm.) in diameter, 3 5-cleft, the lobes 

 crenately toothed or incised, finely pubescent above and beneath; 

 peduncles very short, 1-2-flowered; flower small, yellow or 

 yellowish, calyx pubescent, outside tube cylindrical, long and 

 narrow, equaling the lobes in length; petals lu'oad, half the length 

 of the calyx lobes ; stamens just equaling the petals in length ; 

 anthers oval-oblong; style undivided, glabrous; exceeding the 

 stamens; ovary glabrous; berry smooth. 



Found in the Rocky Mountains of Colorado and New Mexico 

 and mountains westward. 



Judging only from the description* and a single specimen, 

 there appears to be little reason for separating R. quercetorum, 

 Greene, from this species. The form so described is found in 

 California, and is said to have fragrant flowers, with yellow fruit. 



18. R. COGNATUM, Greene. t 



Described as follows : " Shrub evidently large and the branches 

 not rigid; younger branches stifily and densely setose-hispid, 

 the 1-3 subaxillary spines short, not very stout; leaves, and 

 especially the long and slender petioles, villous-pubescent; flowers 

 3-5, at the ends of long and slender pendulous peduncles; 

 calyx salver form, the long cylindrical tube villous-pubescent, 

 twice the length of the oblong segments, the whole apparently 

 flesh -color; petals spatulate-obovate, truncate or refuse, not 

 equaling the calyx segments; bracts of the raceme rounded or 

 subreniform, glandular-ciliate ; ovaries glabrous. 



"River banks at Pendleton, Oregon, May 17, 1896, Thomas 

 Howell. B. leptanthum is the nearest relative of this."
