Gen info
- Gardenias are members of the madder or Rubiaceae family. The genus is names for an 18th-century Ameriican physician and naturalist, Alexander Garden.
- Gardenia comprises abut 120 species and occurs in Africa, tropical and subtropical Asia, northern Australia and Islands of the Pacific. About 10 species occur in the Malesian region (Malaysia, Indonesia, New Guinea, Philippines, and Bruneii). The status of G. pesudopsidium is unclear. (2)
-   Incertae sedis  (enigmatic taxa): Gardenia pseudopsidium (Blanco) Fern.-Vill. is considered a doubtful name, to which some authors have referred the endemic G. barnesii Merr. (1)

Flowers are fragrant, white, but turning yellow, 7 to 10 centimeters long, and 5 to 8 centimeters wide. Calyx-tube is obscurely ridged, and the upper half linearly segmented, green and smooth. Corolla-tube is 5 to 6 centimeters long. Fruit is green, hard, ovoid or somewhat rounded, 5 to 7 centimeters long, obscurely ridged longitudinally, and terminated by the calyx crown. Seeds are many and embedded in pulp.
