Open flowers (30-)37-52 (-60) cm in diameter (in flowers described as R. zollingeriana sizes of 20-25 cm reported).
Fruit with cupule 11 cm in diameter, 7-8 cm high, diameter in upper part 7.5 cm, ovarial part 1-2.5 cm high and 5-10 cm wide, side of column with about 40 grooves.
Ripe seeds 0.8-0.9 mm long, 0.4 mm thick, light-brown to dark-brown.

Lampong present, close to extinction present, now extinct? present
Malesia: S Sumatra (Lampong, now extinct?), C and E Java (close to extinction), possibly formerly also in Bali.
Ecology
Host species most commonly Tetrastigma leucostaphylum (Dennst.) Alston ex Mabb., but possibly also T glabratum (Blume) Planch.
Notes
A medium-sized Rafflesia, at first sight much like R. arnoldii but the lower side of the diaphragm often covered with ramenta. Warts on the perigone lobes are a mixture of larger and smaller ones, more or less as in R. keithii from Borneo. The flower tube is more or less covered with very short knob-like ramenta, not more than one mm long, in some forms partly missing.
A form from East Java, with smaller flowers and ramenta almost absent in the lower part of the flower tube, was described by Koorders as R. zollingeriana. Ervizal (1989) found there in 1989 still viable populations.
