PLATE CXL. 



Represents another Chhdngurd. 



a had also two whorls; the inner consisted of 9 carpels, and the outer of 11 carpels. In the 

 same way that a flower can become double, by an additional whorl of petals, so I think 

 a fruit can double itself, by an additional whorl of carpels. 



b is a section across the base. At A there appear to be oil-cells or rudimentary carpels. 



c is a section close to the base of the fingers. At B there appears to be a ring of oil-cells, or 

 a rudimentary inner rind. 



d was an unripe, but still more interesting specimen of a Chhangurd. It appears to indicate a later 

 period than a in the morphological history of the citrus. Its digits are still ununited, 

 but closed upon themselves, like the fingers of a closed fist, preparatory to complete 

 union and formation of the modern closed rind of the fruit. 



e is a longitudinal section of d, showing no indication of an inner whorl. This specimen appeared 

 to be a single fruit.
