ovary, and in the fruits and petals ; at the same time, it bears some affinity 

 to C. grandis in the shape of the leaves. Flowers of the present species 

 are smaller than those of the latter, but totally different in the shape of 

 the anthers. In the present Citrus, they are obtuse at the apex, while in 

 C. grandis they are apiculate. Calyx is glabrous in the former, but it is 

 hirsute in the latter. This is very probably a hybrid between C. Aurantium, 

 C. sinensis, C. nobilis and C. grandis.
