however, a flower would have the interior of the tube or throat 

 of a more strongly tinged hue than the lobes, or vice versd. 



Thus, B. multicolor (lemon) x Lord Wolseley (red-orange) 

 = No. 403, which has light crimson lobes and a yellow tube. 



B. Teysmannii (golden yellow) x B. multicolor, var. Curtisii 

 (crimson), as well as the reciprocal hybrid, has a rose-coloured 

 throat with a yellow-orange limb. 



B. multicolor (lemon) x Aurora (yellow-orange) = No. 460. 

 This has a yellow tube with red-orange lobe. The reciprocal 

 cross is the same. Princess Frederica (yellow) x B. multicolor 

 (lemon) = No. 339, has a pink* throat and a yellow limb. 



The stigma and anthers are very often quite different from 

 the corolla, frequently retaining an ancestral colour, which is 

 lost or inconspicuous in the corolla. Thus e.g. Princess Frederica 

 has orange anthers, the corolla being yellow ; while in Queen of 

 the Yellows the anthers are crimson. 



6. Prepotency of Colours. — It not infrequently happens that 

 the colour of one parent will be almost or entirely prepotent 

 over that of the other, and be transmitted to the offspring. 



Lord Wolseley (red- orange) x B. Teysmannii (golden-yellow) 

 = Yellow Perfection. On the other hand, B. multicolor, var. 

 Curtisii (crimson) x B. Teysmannii (yellow-golden) = No. 474 

 (crimson). The former species very frequently transmits its 

 crimson colour unaffected by the other parent. 



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

 = Duchess of Edinburgh and Duchess of Connaught (bright 

 scarlet-crimson). 



Monarch (yellow-orange) x B. malayanum (cerise) = 

 Little Beauty (cerise). 



7. Bestoration of Colours. — In some cases a particular colour 

 is, so to say, in the blood, and, though eliminated more or less 

 entirely in one generation, may reappear in the next without any 

 fresh infusion ; or, if there be a trace of it, as e.g. in the anthers 

 alone, it appears capable of redevelopment till it becomes pro- 

 nounced in the next generation. Thus, Monarch (orange) is the 

 offspring of Princess Alexandra (white) x Duchess of Edinburgh 

 ( scarlet-crimson) ; but this latter is a hybrid resulting from cross- 

 ing B. Lobbii (crimson) with 12. Brookeanum, var. gracile (yellow). 



* The pink is traceable to the grandparent Princess Koyal.
