and was named R. intermedium by Carriere in 18G7. This name not be- 

 ing tenable because of the R. intermedium Tausch, 1838, Schneider 

 changed it to R. carricrei. R. carrierei is intermediate between its 

 parents. From R. glutinosum it draws the vigor, the size of the buds, the 

 raceme, the bractlets, the forms and the coloring of the flowers and the 

 small rounded glands; from R. nigrum, the form of the leaves, of the 

 anthers, and of the pistil, as well as the fruits ripening rather early."

40426. Ribes petkaei'm caucasicum (Bieberstein ) Jancz. 



Caucasian red currant. 

 " 7425." 



" Shrub 1 to 3 meters, with young shoots almost always pale, usually 

 glabrous, rarely dotted with glands or with glandular hairs. Buds a 

 little larger than in R. rubrum, colored with dark brown already at the 

 end of May, and easily distinguished at this time. Leaves usually 

 rounded, up to 15 cm. long and broad, 3 to 5 lobed, rarely trifid. with 

 lobes lengthened and subacute, or short and obtuse, with base trun- 

 cate, subcordate or very deeply cordate, smooth or roughly rugose, gla- 

 brous, or subpubescent, even dotted with glandular hairs or subsessile 

 glands, shiny or dull above, glabrous, subpubescent. or pubescent be- 

 neath. Flowers subcampanulate, whitish, salmon colored, or purple, 

 glabrous, or subpubescent. Fruit more or less compressed at the ends 

 like a bergamot pear, red or blackish purple crowned with a withered 

 flower with circular insertion. Flesh juicy, colored, more or less acid, 

 resembling a little the bilberry (Vaccinium vitis-idaea) in its taste. 

 Ripens in July. Germination slow, in six to eight months. Native of the 

 high mountains of Europe and North Africa (summit of the Atlas), and 

 almost all of Siberia, even as far as the River Indigirka, perhaps even to 

 the Okhotsk Sea. Inhabiting so great a space, R. petraeum presents 

 varieties which are distinguished by their habit, foliage, racemes, color 

 and form of flower, and coloring of the fruit. Among these is the variety 

 caucasicum. Shoots glabrous or subglabrous. Leaves rounded, up to 13 

 cm. bread and 12 cm. long, ordinarily 5 lobed. the lobes little developed, 

 subobtuse, with base very deeply cordate, smooth, subglabrous, or pubes- 

 cent. Racemes sometimes lengthened, even up to 10 cm. Flowers red- 

 dish. Receptacle furnished with five tubercles below the petals. Fruits 

 red or blackish purple. From the Caucasus." (E. Janczewski, Mono- 

 graphie des Groseilliers, p. 290.) 



40427. Ribes curvatum Small. Gooseberry- 



" 7428." 



"A low, deciduous, busby shrub, less than 3 feet high ; the shoots smooth, 

 purplish, armed with slender, simple or triple spines. Leaves roundish, 

 usually 1 inch or less in diameter. 3 to 5 lobed. toothed, slightly downy; 

 stalk slender, downy. Flowers produced singlj or in pairs (rarely more) 

 on pendent stalks, white; calyx bell shaped with linear, much reflexed 

 sepals one-fourth inch long; petals very short, white: ovary covered with 

 resinous glands; stamens one-fourth inch long, erect, both they and tin-

 Native of the southeastern United States, apparentlj hardy. 1 broughl 

 plants from the Arnold Arboretum to Kew in July, 1910, which, so far as 1 

 am aware, were the first introduced into this country. It is closely allied
