Note
|
Dodonaea viscosa can be distinguished by its long, narrow, viscid, simple leaves. In Panama the phenology of the species is not well known. It has been col- lected in flower and fruit throughout the year elsewhere in Central America. Most collections have been made in the dry season from December to April.

|
Distribution
|
The species is widely distributed in the tropics of the world. It is more com- mon elsewhere in Central and South America, especially in the dry regions of the Andes. In Panama it is known only from the western highlands and from near the Caribbean coast. Elsewhere in Central America it is reportedly common on arid serpentine soils.
