Abstract
Collections made in Zamboanga Peninsula in 2021 were identified as Sulettaria longituba, a species occurring in nearby Borneo, as well as Peninsular Malaysia and Sumatra. Sulettaria is therefore reported here as a new generic record for the Philippines, increasing the number of ginger genera in its flora to 18. Previously, the genus was known to occur in Sundaland crossing Wallace's line to Sulawesi and is found as far east as the island of Seram. The most closely related genus is Geocharis, which differs from Sulettaria by having staminodes, a bilobed labellum and ridged fruits. A detailed description of Sulettaria longituba based on the recent collections in Zamboanga is provided here. In addition, information is provided on etymology, ecology, distribution, local name and use, as well as a colour plate and detailed line drawings of the reproductive parts.
