HYBRIDS 191 



Paxton observed this hybrid in the nursery of Chandler & Sons, Vauxhall, and 

 states that it was "raised accidentally from seed of a variety of R. catawbiense 

 twenty-five or thirty years ago." He describes it as "a very compact dwarf shrub, 

 decidedly evergreen with small and dense foliage and numerous clusters of pretty 

 pale pinkish lilac blossoms in which there is a variety of delicate tints approaching 

 to white in the center. It has quite the habit of a Rhododendron and looks like a 

 small close-growing, pale-flowered variety of R. ponticum" Herbert had appar- 

 ently this hybrid in mind when he says (Amaryll. 360) : "The fragrance of the Aza- 

 leas has been communicated to the Rhododendrons both by the Mitcham crosses 

 and that of Mr. Chandler." To the Mitcham crosses, however, I have found no 

 other references. 



Here may belong: 



Rhododendron elegantissimum Davies apud R. D. in Gard. Chron. ser. 2, XII. 

 200 (1879). 



"Early White Azalea" x R. Hendersonii R. D., I. c. 



This is said to have white flowers tipped with deep lilac and of agreeable fra- 

 grance. I assume that under Early White Azalea an early flowering form of R. vis- 

 cosum is understood, as the flowers are very fragrant and R. Hendersonii, a name 

 for which I can find no other reference except Millais, Rhodod. 38, and which is 

 possibly one of the R. catawbiense hybrids. 



Rhododendron roseum odoratum Davies apud R. D. in Gard. Chron. ser. 2, XII. 

 200 (1879). Vilmorin& Bois, Frut. Vilmor. 175 (1904). 



"Early White Azalea" x R. Brayanum R. D., I. c. 



This is described as similar to the preceding, but with rose-colored flowers. 

 Rhododendron Brayanum is mentioned by Millais, Rhodod. 35. 



Rhododendron ? calendulaceum x ? catawbiense. 



Rhododendron ponticum var. azaleoides Torloniana Morren in Ann. Soc. Agric. 



Bot. Gand, I. 21, t. 4 (1845). 

 ? Rhododendron Tolerianum hort. apud Zabel in Beissner, Schelle & Zabel, 



Handb. Laubholz-Ben. 379 (1903), name only. 



Nothing is said of the origin or parentage of this hybrid form. The flowers 

 much resemble in size, shape and color the plant figured by Guimpel as R. azaleoides 

 mentioned below, but the upper lobe shows a large orange blotch while GuimpePfl 

 figure does not show the slightest trace of orange or yellow; this and the shape 

 of the corolla seem to indicate the influence of R. calendulaceum. 



I am not aware that this plant is at present in cultivation, though it is certainly 

 one of the handsomest of this group of hybrids. 



Rhododendron azaleoides Guimpel, Otto & Hayne, Abb. Fremd. Holzgew. 15, 

 t. 15 (1825), not Dumont de Courset. 



Osmothamnus fragrans De Candolle, Prodr. VII. 715 (1839). 



Osmothamnus pallidus De Candolle, I. c. (1839). 



Rhododendron fragrans Maximowicz in Mem. Acad. Sci. St.-Petersb. XVI. 



No. 9, 16 (1870). 



Rhododendron pallidum Diimmer in Gard. Chron. ser. 3, LIII. 264 (April 26, 

 1913), not R. pallidum W. Watson in Gard. Chron. I. c. 230 (April 12, 1913). 

 Diimmer seems to consider Azalea pallida Turcz. as specifically distinct, but 

 even if we unite it with Azalea fragrans the combination R. pallidum cannot be 

 used in place of R. fragrans, as it is antedated by W. Watson's name which, though 

 insufficiently described, should stand as the name of the hybrid for which he in- 

 tended it. (See also C. P. Raffil's remarks in Gard. Chron. I. c. 332.)
