la face interne des sepales." The name purpurea has however already been 

 used for another form. This variety is one of the parents of B. ottawensis 

 (see above). The young shoots, too, are often somewhat purplish.

 The origin of the yellow-variegated form seems to be unknown. Kirch- 

 ner says: "Eine Spielart mit grossen, rundlichen, gelbumsaumten Blat- 

 tern, die wir unter obigem Namen aus den Flottbecker Haumschulen 

 erhielten. Ob dies dieselbe Form ist, die Prof. Koch (Wochenschrift iv. 

 94) als B. marginata zu B. canadensis Prsh. zieht, vermogen wir nicht zu 

 sagen." B. vulgaris aurea Jager, Ziergeholze 127 (1865), refers to the 

 color of the flowers, and Jager probably had the doubtful B. aurea of 

 Tausch in mind. 



B. vulgaris f. Egbertii Schneider, c. n. — B. purpurea Egbertii Hort. ex 

 Gibbs in Jour. R. Hort. Soc. xxxiii. 348 (1908).— -I know this form only 

 from the following statement of Gibbs: "The purple leaves are faintly 

 striped or powdered with white." It may be only a subform of f. atro- 

 purpurea.

Schrader says as to the origin: "Hab. in Iberia." I have seen his type, 



and I know of no form from Iberia or western Asia that might be even 

 compared with it. According to the type and Schrader's own description 

 B. lucida is nothing but a form of B. vulgaris. There is no character point- 

 ing to any hybrid influence. Specimens from Kew, collected on May 11, 

 1880 and August 11, 1882 differ from typical B. vulgaris only by their 

 smaller fruits which measure scarcely up to 7 mm. in length. What I 

 know under the name of B. lucida in our gardens has purple shoots and 

 has nothing to do with Schrader's true form.
