Rhododendron.  From A. Wœikoff, Novospassko, Russia.  Deciduous 
or semievergreen shrub up to 6 feet high with bright, rosy-purple

(August to September), tall shrub or flat-topped tree with large,
light-green, compound leaves with winged stalks; and creamy-white

Africa.  The karree boom of southwestern Transvaal and adjacent
Bechuanaland.  Valuable hardwood tree with odd-pinnate leaves;
for regions of limited rainfall, 10 to 15 inches in winter.  Fruits are

40717. RHUS POTANINI. Sumac. Collected by F. N. Meyer
in mountains near Kuanyintang, Shensi, Chuia. Tall shrub or
sometimes tree, 60 feet high. Foliage brilliant in fall.  A gall insect
produces large, inflated galls called "gall nuts," utilized extensively
for black dye, great quantities being exported from Hankow.

37621. RIBES ALPINUM. Mountain currant.  From R.
Irwin Lynch, curator. Botanic Garden, Cambridge, England. A
deciduous, unarmed shrub, 6 to 9 feet high, of dense, close habit.
Leaves broadly ovate, 3 to 5 lobed, shining on the under surface,
½ to 1½ inches long.  Currants red, not edible.  Although it has no
special beauty of flower or fruit, it makes a neat, pleasing hedge
shrub for cold regions, admirable for shady places.

RIBES NIGRUM. Black currant.  A collection of 16 difterent
varieties of this fruit, which ranks among the hardiest of all small
fruits for extreme northern localities.  In England black currant
jelly and jam appear to be more keenly appreciated than they are
in America.  These various imported varieties were furnished by
W. H. Fairfield, of the Canadian Government Experiment Station, at
Lethbridge, Alberta.
