Redvein Abutilon, the Chinese Lantern Flower
These were growing seemingly wild around our lodge, San Isidro, in Ecuador. Supposedly they do not occur naturally there being from Brazil and Argentina, but they weren't growing in any kind of tended beds and we even saw some along the forest trails. Still, very cool little flowers that indeed look just like tiny Chinese Lanterns.
"Abutilon pictum", syn. "Abutilon striatum", is a species of flowering plant in the family Malvaceae. It is native to southern Brazil, Argentina, Paraguay and Uruguay. The plant has become naturalised in Central America, and is used in horticulture.
