296 WILSON EXPEDITION TO CHINA 



INDIA. Kashmir : " Himal. Bor. Occ. Reg. temp. 4-6000 ped.," T. Thomson 

 (sub nom. M. tatarica L.; cf). Pondicherry : without precise locaHty, G. S. 

 Perrottet (No. 454; with fruits). 



I do not know where M. alba really comes from, but its native country seems to 

 be China. The only specimen from China which may represent the wild form is 

 Wilson's No. 3303. The young 9 flowers have sessile stigmas which are not at all 

 hairy on the inner surface, but are only covered with very minute papillae. The 

 perigone lobes are broadly obovate and glabrous, with the exception of a very fine 

 ciliation on the margins. The sepals of the d' flowers are ovate-oblong, almost 

 acute at the apex and minutely pubescent on the outer surface. In the other 

 specimens the stigmas are somewhat more distinctly papillose-hairy and always 

 sessile or subsessile. It is impossible to mention here all the forms of this species, 

 which has been cultivated for many centuries in the warmer and tropical parts of 

 the Old World. I have quoted above the most important synonyms which, in my 

 opinion, should be referred to M. alba sensu lato. 



Except in the cold northern parts and on the higher mountains this tree is 

 cultivated everywhere in China for its leaves, which are used for feeding the silk- 

 worm (Bombyx mori). It is also common by waysides as an escape, and it is 

 quite impossible to state where in China it is genuinely wild, although it is cer- 

 tainly indigenous somewhere in that country. It is also largely cultivated in Japan, 

 and there too it is naturahzed by waysides. This tree is too well known to need 

 any description, but I may state that the fruit when ripe is usually dark red or 

 black and only occasionally white, though often fruit of all three colors may be seen 

 on the same branch. The Chinese name for this tree is Sang-shu.
