Gustavia angustifolia is a small tree, native to South America, with large white flowers.

[2] G. angustifolia has an abaxial leaf surface that is covered in short, fine velvety hairs which is an uncommon trait among the genus Gustavia.

[2] Gustavia angustifolia is native to the dry deciduous forests of the coastal plain of Ecuador and Colombia.

[3] In addition the hairs also provide a barrier between the leaf and the air thereby reducing the amount of exposed surface.

[3] Deflecting sunlight and decreasing exposed surface area of the leaf are both adaptations for preventing water loss in the plant.
