PLATE I 



o and 5 are the Aurantium acidum, copied from Rumphius's Flora Amboyn. (Table 33, Vol. II.) 



Miquel considers this Aurantium acidum of Rumphius identical with Citrus vulgaris of 

 Eisso. In my opinion it is a Seville orange. 



c and d are the bitter orange of Hagkala, Ceylon. The surface was of a deep orange, foveolate 

 and polished. The colour was vivid, approaching lobster red. It had a flattened 

 mammilla round the apex, where there was a souppon of roughness. 



The pulp was orange, and the juice abundant ; sour, and slightly bitter. The oil-glands 

 of the rind small, centre solid ; seeds white, when cut. 



I consider this a Seville orange. The leaves were like those of other Se"villes, lanceolate 

 with winged petiole, and distinctly aromatic.
