Pandanus dubius
species of plant in the family Pandanaceae
Pandanus dubius, commonly known as bakong or knob-fruited screwpine, is a species of Pandanus (screwpine) native to Island Southeast Asia, New Guinea, and the Western Pacific islands (Melanesia and Micronesia), and possibly also to the Andaman and Nicobar Islands.
Taxonomy
Pandanus dubius was first described by the German botanist Kurt Polycarp Joachim Sprengel in 1826. It is classified in the subgenus Rykia, section Hombronia.
Description
Bakong grows to about 3 to 10 m (9.8 to 32.8 ft) high with numerous thick prop roots and aerial roots. The leaves are lanceolate in shape with shallow serrations along the edges. The leaves are around 2 m (6.6 ft) long and 11 to 16 cm (4.3 to 6.3 in) wide, and dark green in color. Bakong are dioecious, having separate male and female plants. The fruits are globular in shape and are around 20 to 30 cm (7.9 to 11.8 in) in diameter.
Habitat
Bakong typically grows on beaches, rocky areas, and limestone outcrops in coastal ecosystems.
Uses
Like other species of pandanus, the leaves of bakong are commonly harvested for weaving mats and other handicrafts in the Philippines, Halmahera, the Bismarck Archipelago, and the Solomon Islands.
This brief starts where responsible research should: with the source description of “Pandanus dubius” as species of plant in the family Pandanaceae. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant in the family Pandanaceae. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Dec 23, 2025. The linked authority identifier is Q15577973. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1826.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
