Distribution – Moluccas, Indonesia

Habitat and Ecology - Epiphyte in the montane forest on Mt. Makina and Mt. Toga. Altitude 200-1200 m. Flowering in January and May in the wild.

Notes - 1. Flowers yellowish white with small black patch on the tip of the lip

3. The epithet amboinensis refers to the location where the specimen was found.

4. Specimens observed: L 0061316 (TYPE G. seramica); L 0043490 (TYPE G. buruensis); L 0324473 ; L0324471

5. L 0324473 (Moluccas) is similar to the type description but with a slightly different shaped lip (acuminate instead of ovate),  L 0324471 (Bismarck Islands) has a longer spathe, floral bract, ovary and spur and the apex of the lip is much more thickened and ornamented with  brown glandular cells.
