Flowers present in January-February, and April. Fruits ripe in June, but can be found in 
April-May. Montane forests, between (100) 700 - 1200 m, constitute the habitat of this 
species.Geografic distribution goes from central Costa Rica to western Panama. 
C. brenesii is not too far morphologically from C. triplinerve, but the relatively long
