You can find tasiste palm “trees” either in grassland savannas (we have found a previous undocumented grassland savanna east of Nakum, Peten) or in tasistal ecosystems. In a grassland savanna there are clusters of tasiste trees perhaps every 5 to 20 meters (the rest of the space is grasses with perhaps some Jicara calabash trees or Nance fruit trees).
In a tasistal you can find half a million or more tasiste palms within an area of 300 meters wide by 3 to 5 kilometers long. Here the tasiste trees are literally solid (with only a few centimeters open space between dense clusters of these trees). Jicara and Nance are not as common here, but we have found jicara in each of the two tasistal areas so far (in the Petexbatun area, Sayaxche, Peten, Guatemala).
Since the savannas and tasistal areas are burned by local people almost every year, the tasiste trees tend to be only 2 to 4 or so meters high. So it is no surprise that botanists say “the palms measure up to 4 meters.” (Laderman 1997: 241). Standley and Steyermark estimate their height up to 8 meters for Guatemala (1958: 278).
Behind Hotel Ecologico Posada Caribe, Julian (owner of the hotel) showed us an area with tasiste palm. Since these are protected (not burned each year) they grow taller each year. I estimate there were lots of tasiste here over 9 meters tall and would be worth measuring them to see if any reached 12 meters in height (since if there are large trees around them, they have to grow tall to get sun). In a tasistal it is “solid tasiste” so not many other trees to shade them.
This Acoelorrhaphe wrightii was so tall I had to back away to try to get most of the palm in a single (iPhone Xs) photo. It’s the tree in the back middle of the photo, with the fronds high in the treetops area. Would be helpful to actually measure it since my estimate of “over 9 meters” is a visual calculation.
But either way, the FLAAR team has now documented a height taller than that for the prestigious Flora of Guatemala botanical monograph. Unexpectedly these respected botanists for Guatemala did not list one single solitary tasiste palm for Peten…they document Acoelorrhaphe wrightii only for Alta Verapaz and Izabal (1958: 277-278).
