P. subterranea distribution [2]

Pinanga subterranea is a species of tree in the Arecaceae, or palm tree, family native to Borneo. [2] [3] It is widespread in the west of the island, where local communities use it for food. [4]

Botany

The species in found in lowland forest valleys 650 metres above sea level and on slopes near streams. It grows well in chalky, red or sandy clay soils. [2]

Ecology

Pollination

P. subterranea has a highly unusual reproductive strategy. Its subterranean flowers are pollinated beneath the surface. The seeds are dispersed by wild boars, which dig into the ground to reach the fruit. [5] Plants that can flower and bear fruit underground at the same time are rare, with only P. subterranea and orchid genus Rhizanthella can do both of these . [4]

<span class="mw-page-title-main">Arecaceae</span> Family of food and ornamental plants

The Arecaceae is a family of perennial, flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem, except for the Hyphaene genus, who has branched palms. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts.

<i>Lodoicea</i> Genus of plant, Coco de Mer

Lodoicea, commonly known as the sea coconut, coco de mer, or double coconut, is a monotypic genus in the palm family. The sole species, Lodoicea maldivica, is endemic to the islands of Praslin and Curieuse in the Seychelles. It has the largest seed in the plant kingdom. It was also formerly found on the small islets of St Pierre, Chauve-Souris, and Ile Ronde, all located near Praslin, but had become extinct there for a time until recently reintroduced.

The Asian palm civet, also called common palm civet, toddy cat and musang, is a viverrid native to South and Southeast Asia. Since 2008, it is IUCN Red Listed as Least Concern as it accommodates to a broad range of habitats. It is widely distributed with large populations that in 2008 were thought unlikely to be declining. In Indonesia, it is threatened by poaching and illegal wildlife trade; buyers use it for the increasing production of kopi luwak.

Trachycarpeae is a tribe of palms in subfamily Coryphoideae of the plant family Arecaceae. It has the widest distribution of any tribe in Coryphoideae and is found on all continents, though the greatest concentration of species is in Southeast Asia. Trachycarpeae includes palms from both tropical and subtropical zones; the northernmost naturally-occurring palm is a member of this tribe. Several genera can be found in cultivation in temperate areas, for example species of Trachycarpus, Chamaerops, Rhapidophyllum and Washingtonia.

The International Palm Society (IPS), formerly the Palm Society, is a horticultural society dedicated to the study of palms, their culture, conservation, and natural history. It was founded in 1956, and has an international membership. It is a nonprofit 501(c)(3) organization. The IPS is known for its publications, grants supporting research, conservation, and education, its conservation initiatives, biennial meetings held in palm-rich localities, and its online interactive forum, PalmTalk.
