HYBRID RHODODENDRONS. 



247 



B. multicolor, var. Curtisii (crimson) x Princess Christian 

 (yellow) = No. 394 (scarlet). 



B. Lobbii (crimson) x B. Brooheanum, var. gracile (straw) 

 = Duchess of Edinburgh (scarlet-crimson). 



2. Beduction of Colours. — As instances of the colour of the 

 offspring being paler than that of the parents, Princess Alex- 

 andra (white) x Duchess of Edinburgh (scarlet-crimson) = 

 Pink Perfection and Princess Beatrice (cream and pink). 



Princess Eoyal (pink) x B. Lobbii (crimson) = Princess 

 Helena (pink). 



Princess Alexandra (white) x B. Teysmannii (golden yellow) 

 = No. 464 (primrose). 



B. Teysmannii (golden yellow) x Taylori (pink) = offspring 

 of different shades of primrose-yellow, as Portia, Juliet, and Purity, 

 in which the pink of the male parent is scarcely perceptible. 



3. Separation, with Elimination of one of the Colours. — 

 Instances occurred where yellow or red was more or less com- 

 pletely eliminated, especially when white characterised one or 

 other of the parents. 



The first hybrid raised was Princess Eoyal (fig 35), by crossing 

 B. jasminiflorum (white) with B. javanicum (orange). In the 

 offspring the yellow of the male parent disappears, while the 

 pink or rose-colour of the same parent is left. A sister hybrid, 

 Jasminiflorum carminatum, of the same parentage, resembles 

 Princess Eoyal in form, but approaches a crimson in colour 

 (fig. 36). A very similar result occurred in several of the 

 offspring of Princess Alexandra (white), crossed by B. 

 javanicum (orange). Most of them are more or less decidedly 

 pink, such as Queen of Eoses, Eose Perfection, &c. In 

 others the yellow is present, but with a tendency to dissocia- 

 tion from the red, as is implied, e.g., in the name " luteo- 

 roseum." In one case, however, Minerva, the corolla is a rich 

 yellow, the red of the orange having in this case disappeared, 

 the anthers alone being crimson. A similar result occurred in 

 crossing Princess Alexandra (white) with the scarlet-crimson 

 Duchess of Edinburgh, the offspring of which, Monarch, is a 

 yellow-orange, while Virgil is a pure yellow ; so that the white 

 of Princess Alexandra has nearly eliminated all the crimson from 

 the male parent. It is remarkable, however, that in a sister 

 offspring, Pink Perfection, the opposite and more usual result
