Diagnosis: 1. Trees, without stipules, leaves simple, alternate, spiraled, rarely arising in small clusters along twigs, entire, oblanceolate with short swollen petioles (Amphitecna). 2. Trees, without stipules, leaves opposite, palmately compound (Godmania, Tabebuia). 3. Trees or shrubs, without stipules, leaves opposite, odd-pinnate, leaflets serrate (Tecoma).
Local distribution: Most diverse in the dry Pacific lowlands.
Diversity: Total: 12 genera, 16 species. Trees: 4 genera, 7 species.
Comments: Only Amphitecna commonly occurs in the cloud forest and rainforest on the upper Atlantic slope. The Tabebuia species and Tecoma often flower en mass, presenting a floral display visible far across the landscape.
