The. variety resembles 

 Citrus Tanhan iu tlowers 

 and leaves ; but the flowers 

 are smallcr, pctals narrow- 

 er, leaves obtuser in the 

 present variety, than those 

 in- the latter. There is 

 no distiiict articuhxtion 

 betweeu the ovary and 

 style in the former, while 

 such is very distiuct in the latter. Leaves of the variety are quite smooth 

 on the upper surface, but those of O. Ihnlcan liave very minute elevated 

 dispersed dots. The flowers of the var. poonensis resemble those of another 

 variety Pon/.;/ ; but the calyx-lobes of the former are obtuser than those of the 

 latter. There are some poiuts which may suggest the present orange to l)e a 

 hybrid between C nohilis and C. grandis. They are tlie anthers and ovary 

 Avliich resemble much those of C. grandis. But, this is, I think, a mere acci- 

 dental feature, all uther cliaracters of the present orange are essentially of those 

 of C. nobilis. In one form, the colour of the shin is like that of Xo. 151 — 

 No. 126, and that of the pulp is No. 131 ; while in another, tho colour of 

 the skin and pulp is likc that of No. 126 in Klin. et Val. Code des CouL 

 This tree, Avhen quite ohl, attains a lieiglit of 5 m. 14 cm., the liranches spread- 

 ing over 4i| m. iu width.
