MORUS 



1428. Teas' Weeping Mulberry. 



fruits are an inch long, but they are oftener only half 

 that length, and one sometimes finds trees on which the 

 fruits are barely a quarter of an inch in length. Now 

 and then a tree bears fruit nearly or quite black. Birds, 



poultry and hogs are 

 fond of these Mulber- 

 ries. The trees are usu- 

 ally very thick-topped 

 and bushy growers, 

 but occasionally one is 

 seen which, when 

 young, has branches as 

 straight and trim as a 

 Northern Spy apple. 

 These half-wild trees 

 are seedlings, and this 

 accounts for their var- 

 -'"'" lability. 



Var . Tatarica, Loudon 

 (M. Tatdrica, Linn.). 

 RUSSIAN MULBERRY. 

 Figs. 1422-25, 1431. A 

 hardy type of Morus 

 alba which was intro- 

 duced into our western 



states during 1875-77 by the Russian Mennonites. It dif- 

 fers little from the type of Morus alba in botanical 

 characters. As commonly seen, it is a low-growing very 

 bushy-topped, small tree with small and much-lobed Ivs. 

 The fruit is usually very small and insipid, and varies 

 from creamy white to violet, deep red and almost black. 

 Var. nervbsa, Hort. Fig. 1429. Lvs. contracted and 

 jagged, and very strongly marked with many white 

 veins. It bears fruit a half-inch long. Among the 

 horticultural curiosities this tree should find a place, 

 although it is not grown by our nurserymen. Its orna- 

 mental value is considerable, especially when striking 

 effects are desired. Rare in America. A large specimen 

 stands in the grounds of the Department of Agriculture 

 at Washington. The history of the Nervosa Mulberry is 

 obscure. Delile described it in a French periodical as 

 long ago as 1826, and it is described in monographic 

 works. It is of horticultural origin. 



The following names, which one may find in horticultu- 

 ral literature, are referable to M. alba: cedrbna(?),colom- 

 bdssa,Constantinopolitdna,globdsa, intermedia, Itdlica, 

 laciniata (of some), lucida,membranacea,macrophyUa\ 

 Moretti, Romana, rosea, urticcefolia. 



BB. Style evident or even prominent. 

 Japdnica, Audib. (M. dlba, var. stylbsa, Bureau) 

 Lvs. usually large, dull, rather thin, long-pointed the 

 rounded teeth very large and deep, or the margin even 

 almost jagged, the leaves upon the young growth usually 

 deeply lobed. China, Korea, Japan. -This species has 

 been introduced lately. It is tender in the North when 

 young. The fruit is described as short-oblong and red. 



latifdlia, Poir., which Bureau refers here, is probably 

 M. Indica, Linn.). Fig. 1432 A. A strong-growing 

 small tree or giant shrub, with dull, roughish and very 

 large, long-pointed Ivs., which are seldom or never 

 prominently lobed, and which are often convex above, 

 bearing black, sweet fr. ; style evident. China, where 

 it is the chief silkworm Mulberry. Once much grown 

 in this country, but not now well known, particularly 

 not in the North.

 Morus alba, var. nervosa. 



AA. Lvs. dull green, mostly rough or pubescent. 

 B. Full-grown Ivs. more than 4 in. long.

nigra, Linn. BLACK MULBERRY. 



green, rather large, tapering into a , 



commonly very rough above, usually not lobed, the 

 base equal or very nearly so on both sides, the teeth 

 rather small and close, the branches brown: fr. large, 

 comparatively thick and fleshy, mostly dark-colored. 

 The black Mulberry is a native of Asia, probably of 

 Persia and adjacent regions. -This is the species which is 

 cultivated in the Old World for its fruit. In America 

 it is very little grown. It is not hardy, except in pro- 

 tected places, in New England and New York. The 

 Black Persian Mulberry of the South and of California 

 is probably of this species. 



rubra, Linn. NATIVE RED MUL- 

 BERRY. Fig. 1433. Lvs. usually 

 large, very various, those on the 

 young shoots deeply lobed with 

 very oblique and rounded sinsues, 

 in the base of which there are no 

 teeth, the upper surface rough and 

 the lower one soft or variously 

 pubescent, the teeth medium or 

 comparatively small and either 

 rounded or bluntish: fr. deep red, 

 or when fully ripe almost black, 

 variable in size, often very good, 

 nearly always having an agreeable 

 slight acidity. Mass, to Fla., Kans. 



and Tex., mostly in rich soils and bottom lands. S.S. 

 7:320. This native Mulberry has been tried for the 

 feeding of silkworms, but with indifferent success. At 

 least three of the named fruit-bearing Mulberries be- 

 long to it, and a yellow-leaved Mulberry, which is
