"Walking Tree" of Costa Rica. Is it Makainki ?????
I was in the jungle of Tortuguero in north east Costa Rica,
and was shown some trees that they called Walking Trees. They stood up in the air on their roots and actually could move a little distance each year. I believe they said their name was something like "Makainki" but I cannot find that word. Can someone tell me the proper name for the Walking Tree in Costa Rica? |

Can someone tell me the proper name for the Walking Tree in Costa Rica? Didn't recall the name "walking tree", but lots of trees in CR and elsewhere do form stilt roots. Searching for "walking tree" finds a few sites with pictures but no scientific names: http://www.robjensen.com/month_featu...es/costa19.jpg http://www.chenry.com/PhotoAlbum/Cos...3/P0000160.JPG http://www.worldexperience.com/pv.ht...0&FileType=jpg might all be palms with large stilt roots. I recall _Iriartea_ species and Socratea species as both being like this. http://www.rachaelvanfleet.com/maste...ica/costa.html looks like an Socratea-type palm to me. http://llk.media.mit.edu/projects/eThinking/tree.html doesn't give a name. http://jajhs.kana.k12.wv.us/amazon/question.htm#ques1 asks your same question, but is just told that there are many trees with stilt roots. The "walking tree" in http://www.photo.net/cr/walking-tree-chantal.jpg isn't a palm, and I doubt it can "walk" http://www.trentu.ca/biology/TEWebPa...dplantlist.htm lists both Iriartea and Socratea species as "walking palm" http://www.strayreality.com/mystery1.htm briefly describes Costa Rica's "walking palms" [Socratea and Iriartea species] http://www.plantapalm.com/vpe/photos...exorrhizae.htm looks about right. http://hk.geocities.com/alhy731/trf/plants.htm http://bio.bd.psu.edu/biobd497g/Cost...tsandtrees.htm : "Walking Palm Socratea durissima" Okay, then. http://www.mobot.org/MOBOT/research/treat/geonom.html has this to say: "Iriartea deltoidea is a widespread and familiar canopy palm, characterized by its dense cone of blackish, spiny stilt-roots and pinnately compound lf.-blades with "fish-tail" shaped, praemorse lflts. disposed in various planes. These features distinguish it from all other Costa Rican palms except for the related and vegetatively very similar Socratea exorrhiza. Close at hand, adult specimens of Iriartea may be told from S. exorrhiza by their darker, more numerous, and more densely aggregated stilt roots [...]" [Wet forests, 0--800 m; entire Atl. slope, Pac. slope vic. Palmar Norte (Fila Retinto) to Pen. Osa. Fl. 1--5, 11--12]. "Socratea exorrhiza is a canopy or subcanopy palm, recognized by its tall, open cone of brownish, spiny stilt-roots and pinnately compound lf.-blades with broadly cuneate, praemorse, longitudinally splitting. lflts., with the segments disposed in various planes. These features distinguish it sharply from all other Costa Rican palms except for the very similar and sympatric (though perhaps more widespread) Iriartea deltoidea, which differs in having a denser cone of blackish stilt-roots [...] [Wet forests, 0--750 m; Atl. slope Cords. Central (to RNFS Barra del Colorado and PN Tortuguero) and Talamanca, Pac. slope V.de El General, Golfo Dulce region. Fl. 2--3. Extr. SE Nic. to Bol., Fr. Guiana, Braz.] So, both species may be near Tortuguero. The ones with larger, looser-spaced lighter-colored stilt roots http://www.rachaelvanfleet.com/maste...ica/costa.html would be the Socratea palms, the ones with denser, darker stilts like http://www.robjensen.com/month_featu...es/costa19.jpg should be the Iriartea palms. Hope this helps. cheers |

See picture at http://boonedocks.net/pa/pa.php?p:339:s:15 To quote from that site, "This tree is known as the 'walking tree' because it can move. If the tree needs to move, it just grows roots on that side and lets other roots die. Eventually the tree is relocated." That would cause the tree to fall over, whice is indeed moving. That tends to be all at once and not a little bit each year though. Right. It doesn't make sense. The whole 'walking' idea seems pretty implausible, especially looking at the symmetrical shape of the cones of stilt roots on these palms. Even if the new roots were strongly contractile [unlikely], they're not forming just on one side, and the older roots aren't letting go as new ones form. If the old roots were dying or being uprooted, and young roots were contractile, any one-sided new root formation ought to pull the tree over, and not move it along horizontally while staying upright. I suspect it's just a myth based on the 'leglike' appearance of the stilt roots. [How would anyone ever know if a wild rainforest palm had moved a few inches or centimeters over a period of years? Any contrary information? cheers |

"This tree is known as the 'walking tree' because it can move. If the tree

It is up on these weird stilt roots, something like a mangrove. You can easily imagine it growing one root at a time in the direction of more food or water, and one root at a time dying off on the other side.

It has been shown time and again that truth is stranger than fiction, so who knows? PvR |

All those pictures show plants on hillsides so they would tend to move downhill. I don't know enough about stilt roots of palms to say anything sensible. It has been shown time and again that truth is stranger than fiction, so who knows? How can the palm move anywhere if the older stilt roots still remain anchored in the ground and don't actually disintegrate [the photos seem to clearly show that they don't]? They're "woody", strong and tough, not at all stretchy. To "walk" the tree might be expeced to pick up its feet. And even if all the older roots did die away as described above [again,not shown in any of the photos] how would the formation of new stilt roots cause the tree to move directionally, if they don't forcibly contract after penetrating the ground? They would just continue to prop it in its original place. Maybe a tree something like this could move along while standing erect if the stilt roots on the "moving toward" side are highly contractile and exerting powerful tensile forces that are being neatly balanced by similar pulls by most of the other stilt roots, while those roots on the "moving away from" side gradually yield and let go, all of them continually being lost and replaced by later-formed roots. But then, the whole stilt root systems of the tree wouldn't look much like the ones in in the photos. These look like sturdy permanent props, not a system of short-lived taught cables that could be pulling the tree along "hand over hand". And again, the early-formed stilt roots still appear to be firmly rooted; they evidently aren't being uprooted and dragged along the ground... I'll bet these palms really don't even budge [apart from during earthquakes and landslides]. For a weird plant that really does make tracks, a favorite example is the "creeping devil" cactus from Baja California [Stenocereus eruca or Machaerocereus eruca]. The large prostrate rooting stems have a typical cactus growing tip at one end and continually die away at the basal end, so the thing looks like a big spiny caterpillar as it roots its way along ["eruca" means "caterpillar"]: http://www.desert-tropicals.com/Plan...eus_eruca.html http://cactiguide.com/graphics/s_eruca_b_600.jpg http://www.hortpix.com/pc4100.htm http://cactiguide.com/Stenocereus.htm cheers |

Still I can envision a palm on a hillside being dragged gradually downhill and being either propped up or being pulled upright by roots (likely only one or the other mechanism, not both). But this is pure conjecture. Even at best it won't be a large scale phenomenon (either in distance covered or number of plants involved). PvR |

PvR When I returned from the last Amazon trip I asked about walking palms on our Palm list. The locals had told me anecdotes about the stilt palms (Socratea and Iriartea species) moving into brighter light, growing the new roots preferentially. I got no scientific answers from the list as to the validity of the stories. One poster from Thailand verified that a Socratea (imported from new world) growing in his extensive palm garden had moved many feet over the years. After reading a bunch of anecdotes posted on the list of palm enthusiasts, I decided it still may be a myth. No one cited any journal reports. Rick |

After asking that, I looked myself. There is one article available on stilt roots in tropical palms. Further searching revealed that the best-known species of the tropical stilt rooted palms are A HREF="http://www.pacsoa.org.au/palms/Iriartea/deltoidea.html" Iriartea deltoidea/A. and A HREF="http://www.pacsoa.org.au/palms/Socratea/exorrhiza.html"PACSOA - Socratea exorrhiza/A There is no mention anywhere of any of these trees "walking", so the whole thing may be a myth, like the deadliness of the Upas tree.
