Nova Grenada, Truando (Schott XII, 1857, AZelastomaceae 
nO. 2). 
This species may readily be recognized by its discolored leaves. 
Its systematical place is next to 7. sudscabrula and sefosa on ac- 
count of the free bracts and the puberulous stems and petioles. 
It differs however from both by the much narrower leaves, and the 
flowers larger than in 7. sudscadruda and smaller than in 7. sefosa.
