Montanoa josei  

A little known tree from an area of high endemism in northern Colombia, Montanoa josei is easily separated from other species of the genus. A number of the more prominent features are the irregular-margined pales that have a deep (2 mm) sinus, the grayish-green leaves and involucre, reddish pubescence on the peduncles and stems, and the long, thin achenes.
