LXXXI. SALVADOEACEyE. 123 



^- Gihson,Coo/ce'.—'DisTRiB. India (W. Peninsula) ; Ceylon, Tropical and South Africa 

 and Madagascar. 



Dobera Boxhurghii, Planch, in Ann. So. Nat. ser. 3, v. 10, p. 191. There is a small 

 scrap of a flowering branch of this in Herb. Kew., on which is a ticket " Bombay, 

 Caj)t. Gehunie," and this seems to be the only specimen obtained from India. Capt. 

 Geburne was an ardent horticulturist in Bombay itself, and used to introduce plants 

 from various places into his garden. No other botanist has found the plant in 

 Bombay, and the inference of its existence there from the solitary specimen referred 

 to seems hardly justifiable. The ticket on the specimen in question is not in Capt. 

 Geburne's but apparently in Planchon's handwriting.
