and fruiting specimens of Roxburgh's trees in the H. B. C, collected before 

 the destructive cyclone of 1861, which shew that the Chittagong tree of 

 Roxburgh is H. Helferi, and that the Hindustani one is the same as Wight's 

 Herb. No. 569 and consequently JET. Amottiana, Hf. The fruits are 

 described and figured as much too ovate. If the ripe fruits and the 

 stigmas of the Burmese species should turn out to be different, Hooker's 

 name (S. Helferi) would have to be restored.
