The plant varies in the size of its leaves. It occurs in Upper Egypt, the Canaries, as 

 well as in Arabia, Aden, Palestine, and Scinde. 



From a manuscript note attached to Salt's Abyssinian specimens, in the British Museum, 

 it appears that the flowers of this species expand in the daytime only, most Abutilons being 

 evening flowerers. It is curious that the same thing has been noticed by Stocks in Scinde, 

 who says of the present species, " Unlike the other Abutilons, this oue expands its flowers 

 in the middle of the day, like the Sidas."
