The large savanna found by Hellmuth on aerial photographs has turned out to be a veritable unexpectedly biodiverse area. We have now visited this savanna two times and Elena Siekavizza has a list of about 80% of the trees that grow in the multiple micro ecosystems within this savanna. The savanna is so large we need to return for one more note-taking day (keeping in mind it is a 6-hour round trip hike from the Nakum camp). But the awesome natural beauty, the presence every hundred meters of another micro ecosystem, and the fact that NONE of this specific savanna has been documented by botanists or ecologists (that we know of) previously, fuels our hiking there plus multiple kilometers going from plant to plant in each different ecosystem within the overall savanna.
Yes, a savanna is a grassland, but it does have trees, a few full size (Crescentia cujete and Acoelorrhaphe wrightii). However most other trees are stunted, either because of the permanent water in the bog under the savanna surface and/or because local hunters tend to set fire to the grass every year.

Ximenia americana is known as pepenance (pepe nance) This is because its red fruits (when they ripen and turn orange) remind you of (orange) nance fruits (stunted nance trees are a hallmark of savannas in Peten and adjacent Belize). But Ximenia americana is in the plant family Olaceae, so not a relative of nance from a botanical point of view.
Other local names in Peten include Saaxnic and tocote de monte (Lundell 1937: 120) plus abalche, jocote, and jocote montaña. Local names in Belize include sour plum, Wild plum, or wild lime (Balick, Nee, Atha 2000: 104), who list the fruit as edible. Lundell also says the fruits are edible (1937: 59).
Lundell lists Ximenia americana on pages 45, 59, 96, 118, 120, 135, 137 and 167 (so I am surprised that Schulze and Whitacre do not have it anywhere in their 1999 list of Trees of Tikal). Cook does not list it in her helpful coverage of ethnobotany of the Lacandon Maya of Chiapas.
But surely Ximenia americana will be found at Tikal, but in the meantime, if you are interested in plants of Mesoamerica, the Parque Nacional Yaxha Nakum Naranjo is a great place to visit.
