The existence is undoubtedly filled with all kinds of amazing flowering plant life species , from those that only appearonce in a blueish moon , to thosefossilized by time , and the more commonwell - enjoy species . Now scientists have line a new species that does something extremely special in the industrial plant worldly concern : it flowers underground .
On the tropical island of Borneo , a native industrial plant has been discovered flowering and fruiting under the grunge . Known by autochthonic people and valued for its yield , this new coinage , namedPinanga subterranea , is the first known species in the palm family to exclusively fruit and flower underground .
Despite the fact that the plant is well known to the local people because of its bright red fruit eaten as a delicacy in some parts of the island , the mintage has remained unnoticed by scientists – even though they have described over 300 other coinage of palm on the island .

Dr Paul Chai was the first to notice this species in 1997 in Sarawak , and 20 age later on in 2017 , Agusti Randi found fruits and remains of the plant , crushed by brute and cut into up by pigs , on the forest trading floor . Palm coinage number as many as 140 in the genusPinangaand Borneo is the center of their diversity , so classify this new species require careful study by Randi , who compared the new specimen to all the get laid Bornean coinage .
“ Without the tip - off from our Malaysian colleague Dr Paul Chai , we probably would have mistaken this exciting newfangled species for an unremarkable palm seedling and would have walked right past it . Instead , we have scientifically line an unbelievably rare caseful of geoflory , that is hugger-mugger unfolding , and the very first known example of its kind in the total palm family . It rightfully is a once - in - a - lifetime find , ” said Dr Benedikt Kuhnhäuser , Future Leader Fellow at Royal Botanic Gardens ( RBG ) Kew , in a affirmation sent to IFLScience .
The processes of plants fruit and bloom underground , eff as geocarpy and geoflory , respectively , have only been seen in 171 industrial plant metal money . One rough-cut example is thepeanut , which develops the yield under the soil after flowering above ground .

To have a flora mintage that both fruit and flush underground is exceedingly rarified and has only ever been seen before in the small orchidaceous plant genusRhizanthella . These adaptation seem counterproductive in terms of cum dispersal , and this has never been seen before in the palm house , specially since most other extremity of the genus are pollinated by bee and beetle species .
“ I have been study palms for 30 class and am amazed at how they continue to storm us . This unexpected discovery poses many more motion than it answers . What is pollinating the palm ? How does the pollinator find the flowers secret ? How did this phenomenon evolve and what on Earth will palm storm us with next ? ” said Dr William Baker , Senior Research Leader – Tree of Life at RBG Kew in a program line air to IFLScience .
One proffer is that the bearded pig bed ( Sus barbatus ) is responsible for dispersing the seeds throughout the rain forest , as observations have revealed that the pig comprehend up the fruits to consume and could therefore be dispersing the semen in their faeces .
The team conclude that there is still much to discover about these unique specie and suggest that this new - to - science discovery spotlight the motivation to more close collaborate with autochthonal people in the future .
The study is publish inPalms(the Journal of the International Palm Society ) , with an accessible newspaper publisher describing the mintage inPlants People Planet .
