Except in the curiously wrinkled leaves and colour of 

 the corolla, Diervilla Middendorffiana resembles D.florida, 

 Sieb. & Zucc. (Weigela rosea,* Lindl. t. 4396), to which 

 species Mr. Hemsley (Journ. Linn. Soc. xxiii. 368) rightly, 

 I think, refers D. amabilis, Carr. (W. amabilis, Hort. t. 

 4893). D. Middendorffiana is the only Old World yellow- 

 flowered species, in which respect it resembles its 

 two New World congeners, D. trifula, Moench. (t. 1796, 

 I), kmnilis, Pers.), and D. sessilifolia, Buckle, both natives 

 of Eastern N. America. It is named after Alexander 

 Theodor von Middendorff, whose travels in Northern and 

 Eastern Siberia, in 1843-4, were published in St. Peters- 

 burg in 1847-56. According to Carriere it was intro- 

 duced into Europe in 1850, and found to be difficult of 



January 1st, 1903.
