PLATE CXXXIX 



The Chhangura (literally, six fingers) or primitive (?) pulpless citron. 



a gives an idea, as I think, of this most interesting and primitive attempt of nature at evolving 

 a citrus fruit. The carpels, although distinct, are united at their base, and free at 

 their extremities. This digitate citron consisted of two whorls, an outer one of 13 

 carpels, and an inner one of 7 or more carpels. In section, more than ten are visible. 



b is a section across the solid part, and c across the part which is just above the union of the 

 carpels. It should be observed that the inner whorl of rind carpels at A is that 

 which at a later period, according to my view, developed into the citrus pulp ; the oil- 

 cells of the rind of the inner whorl becoming the juice-vesicles of the pulp. (Viiie 

 Chapter on " Morphology. ") The hollow space at A was filled up with some withered 

 carpels. 



d, e, and / are the leaves of this citrus, and g its spine. The leaves have a lemon scent.
