Merrillia is a genus with a single species, Merrillia caloxylon, a tropical forest tree of the citrus family that can reach 20 to 30 metres. It is a rare, large tree of Malaysia, Thailand and Sumatra, not a typical garden plant.
Merrillia is a monotypic genus of flowering plants in the citrus family, Rutaceae, containing the single species Merrillia caloxylon. Its English language common names include flowering merrillia, katinga, and Malay lemon. In Malaysia it is called ketenggah and kemuning gajah. The species is native to Malaysia, Thailand, and Sumatra in Indonesia.
This species is a member of the Rutaceae subfamily Aurantioideae, which includes the genus Citrus. It has been placed as the only genus and species in the subtribe Merrilliinae, which are known technically as the large-fruited remote citroid fruit trees. The genus is sunk into Murraya by some sources, but accepted in a 2021 classification of the Rutaceae.
The species has been noted for its wood, which is bright yellow with dark brown streaks. It is a hard wood used historically in Malaysia to make walking sticks and kris handles. It was also good for making furniture and boxes. The species was too rare to provide a supply of commercial timber.
