Though differing a little from A. de CandoUe's excellent 

 description in the smaller size of the petals of the mule 

 flower, and in the somewhat larger capsules, I cannot 

 doubt this being Raddi's Begonia angularis, which is said 

 (A.DC. I.e.) to have been introduced into English gardens 

 in 1845 from San Gabriel, in the Sierra d'Estrclla of 

 Brazil. There are specimens of it in the Kew Herbanum 

 from the Organ Mountains, collected by Barchell, and 

 from Rio (probably the Organ Mountains) by Glaziou. 

 Martius gives the Province of Rio de Janeiro and Mmas 

 Geraes ; and A. de Candolle in the Prodomus cites Schott 

 as its discoverer in 1822, at San Joao Marques. 



B. angularis is a magnificent species, of shrubby habit. 

 The plant from which the figure is derived is eight feet
