ENUMERATION OF THE SPECIES 99 



which it resembles in habit." This interesting Azaleodendron was raised by a 

 nurseryman at Norbiton, Surrey, named W. Smith, and exhibited before the Horti- 

 cultural Society of London in the spring of 1842. It is not now in cultivation in 

 this Arboretum, not being sufficiently hardy to withstand the winter's cold. A 

 specimen in this herbarium under the name of Rhododendron " Victoria regina " 

 and from an exhibition held by the Massachusetts Horticultural Society on April 

 19, 1889, evidently belongs here, but whether the name it was exhibited under has 

 any standing I do not know. 



Another hybrid between a broad-leaf evergreen Rhododendron 

 and R. molle G. Don is: 



X Rhododendron "broughtonii aureum" Hort. apud W. Watson, 

 Rhodod. and Azaleas 93 (1911). Osborne in Gard. Chron. ser. 3, 

 LI. 53. fig. 29 (1912). Bean, Trees and Shrubs Brit. I si. II. 345, 

 fig. (1914). 



Osborne in his account of this plant says it " obtains its name from the village 

 of Broughton in Peebleshire, where it was raised by crossing a yellow Azalea and 

 a seedling evergreen Rhododendron." Both Osborne and Bean regard this as the 

 best of its class. It has been in cultivation in this Arboretum since 1910 but does 

 not thrive. More recently M. G. Vander Meulen has raised hybrids between R. 

 molle and the evergreen Rhododendrons " Prince Camille de Rohan " and " Leo- 

 pard " which he names " Edouard AndrS," "Director Rodigas" and "Dr. 

 Masters." Mr. White of Sunningdale has raised similar hybrids. Millais (Rhodod. 

 214 [1917]) says that they retain their leaves in winter, and are quite hardy and 

 very floriferous.
