Begonia xanthina, Hook, Bot. Mag. t. 4683. 



Although many different species of this valuable genus have 

 been discovered up to this time, we have had only those with white 

 or red flowers. B. cinnabarina with its orange red flowers was an 

 approach to what we now figure — the Begonia xanthina. But even 

 the yellow of this is shaded with the red which prevails in a 

 greater or less degree in the flowers or leaves, and stalks of all the 

 genus. 



This species, which flowered in July, 1852, in the collection of 

 Mr. Nuttall, at Rainhill, Lincolnshire, was received by bim in 1850, 

 from the Bootan Himalayas, having been sent thence hy his ne- 

 phew, Mr. Booth.
