Hura polyandra tree in Guatemala
This remarkable tree grows from Mexico through Guatemala and southward. We searched for this tree because we are always looking for trees with conical spines, since the Classic Maya considered trees with conical spines or bark with crocodile-like roughness as sacred.
Although it turned out that the Hura tree with abundant conical spines was not H. polyandra, the tree was definitely worth studying due to its explosive seed pod. We have a separate PDF on the pods, which we have been studying in detail.
The flowers come in a male size and shape and a female size and shape. These flowers are quite remarkable shape for a tree this size (Hura can grow to considerable size). So there is a lot about this tree which encourages me to continue to study it, and to do detailed photography to assist botanists and students who are not able to wander around Mesoamerica looking for trees.
Here is an introductory bibliography on Hura polyandra and its relatives.

We have a basic information about Hura polyandra trees on our Mayan ethnobotany web site.
First posted April 2014 after finding many more Hura polyandra trees along another river, this time in the dry Zacapa area of Guatemala.
