PLATE COLIX. 



These figures are taken from the monograph on the Citrus of Eieso and Poiteau. 



a and b are there called " Bigaradier bicolor." It was yellow, with green stripes, when unripe, and 

 yellow with orange stripes, when ripe. 



c and d are called "Bigaradier bizarrerie." The smooth parts were of an orange colour, and the 

 warty parts of a yellow colour. They appeared a mixture of an orange and a citron 

 in one fruit. 



A seedling is also mentioned, which, on the same tree, had both white flowers and others 

 tinged purple. Mention is also made of similar mixtures between the apple and the pear. 



NOTE. The whole subject of the hybridization of the different varieties, or species, of 

 citrus requires to be carefully gone over by direct experiment, not only to determine certain 

 purely scientific points, but to see whether new and useful varieties might be obtained by 

 crossing. 



N.B. These are like the so-called Trifacial oranges of other writers
