in all respects, except in having three styles instead of 

 one, — a character, that, supposing Linnaeus to have made 

 no mistake, is of little importance in the order to v^hich 

 Thryallis belongs : this species also confirms the propriety 

 of deferring the genus to Malpighiaceae, rather than to 

 Tricoccae (Euphorbiaceae), as was done by Linnaeus. 



This new species was found near Rio Janeiro by the 

 late Mr. Forbes, who sent seeds of it to the Horticultural 

 Society, in 1823. Our drawing was made at the Chiswick 

 Garden, in October 1827. •
