PLATE CXVIII. 



a and b is a ripe true Mandarin, plucked from a tree in the Peradeniya Botanic Garden, 

 Ceylon. Dr. Trimen told me that in 1847 H.H. Ibrahim Pasha, of Egypt, sent 

 a collection of orange plants to Peradeniya, and that probably these Mandarins 

 were descendants of some of them. The rind and leaves of the true Mandarin 

 have an aroma distinct from all other orange trees that I have seen, although it 

 is allied to that of the Keonla of India. The exterior of this orange was smooth 

 and shiny ; oil-cells distinct, as shown at A. It was not perfectly ripe, and the 

 colour was orange-yellow (December) ; skin thin, and loosely adherent to the pulp ; the 

 latter being orange-yellow, with large cells, as shown in one of the carpels ; seeds 

 green, when cut. The rind had an aroma distinctly that of a true Mandarin ; juice 

 abundant, and of a very pleasant flavour. The oil-cells of the rind project like 

 little balloons into the scanty, and white loose areolar tissue. 



c is a rain leaf, and d and e spring leaves, both with a sui generis aroma. 



f and g is a ripe Mandarin orange from the Etawah Jail Garden, introduced from Lucknow. 

 Exterior bright orange, foveolate and chagrined, especially round the apex. The 

 typical shape is slightly pyriform ; some are more globose. Pulp orange ; seeds green, 

 when cut; centre hollow. In this and the Lucknow climate and soil the pulp is 

 dryish, h is a rain leaf; i, j, and k are spring leaves; I its spines. Often it is 

 spineless.
