This form I received as B. serotina from the Botanic Garden at Copen- 

 hagen in flowering and fruiting specimens collected in June and October 

 of 1916 (no. 4814/27). The type had been raised from seeds of B. serotina 

 J. Lange in memory of whom I name it. Quite identical with the 

 type is another form from the same garden collected at the same time and 

 raised from seeds of B. Guimpelii (no. 4814/21). Both show the influence 

 of B. vulgaris in their large leaves, the color of the branchlets and in their 



strong spines.

thorns, the distinctly brown-red young twigs, and the shorter inflorescence; 

 from var. oblanceolata they may be distinguished by their wider, much less 

 dentate or almost entire leaves and by the color of the twigs. In its habit, 



var 



resembles more B. chinensis. A specimen from Kew, collected October, 

 1916 (no. 14, received under no. 59-03 from Berlin as B. Guimpeli) seems 

 to belong to var. Langeana or typical laxif.ora. A synonym of it may 

 be B. sulcata Koch et Bouche (in Ind. Sem. Hort. Berol. 1854, App. Gen. 

 Spec. nov. p. 12), so far as can be judged from the description only. 



To understand clearly this hybrid and other critical forms found in 

 gardens one should be well acquainted with the true B. chinensis of which 

 I will add the following description and remarks.
