Doubtful Species 
(31) G. opaca King, lx. 160. 
Tree 30 to 40 ft. tall, 4 to 6 in. through. Leaves thin coriaceous, 
lanceolate rather long cuspidate, base cuneate; nerves quite invisible, 
4 in. long, 1*25 in. wide; petioles -25 in. long. Flowers female, 
solitary terminal. Petals oblong *25 in. long. Pistil cylindric 
narrowed at top. Stigma obscurely lobed. Fruit bright red 
top-shaped, nearly 2 in. long, 1-25 in. through. Hab. Perak. A 
rare mangosteen tree. Dense jungle near top of Gunong Malacca, 
3500 to 4000 ft. altitude (Kunstler 7232). 
The flower resembles that of G. anomala Planch, but the foliage is totally 
different. King's description of G. opaca appears to belong partly to this 
plant, but two out of three specimens so labelled by King are G, Hombroniana : 
Male flowers not known.
