THORNFOREST/SCRUB OF THE
NORTHWEST
Thorn forest occurs in several places in Mexico, not just in
the Yucatan. Along the Pacific coast of southern and central Mexico as far south as
Acapulco there's a lot, and pockets of it appear in Tamaulipas and Veracruz. Wherever it
appears in Mexico, members of the Bean Family, the Leguminoseae, are foremost among
the woody plants, and these trees and bushes usually bear spines and/or thorns.
The main Bean-Family genera are Acacias, Caesalpinia, Cassia and Mimosa.

Bean Family members are such common, remarkable trees that we have a
special page here.
THE CACAO OR CHOCOLATE FAMILY, the Sterculiaceae
Bay Cedar, called Pixoy in Maya, is Guazuma
ulmifolia. With its simple leaves with serrated margins the tree looks more like a
stunted elm than a cedar. I guess the name cedar derives from the fruits, which look
vaguely like the green, roundish cones of junipers, which in some places are called
cedars. You can see three green, spiky fruits on the branch at the right. By mid
dry-season, around January, this tree gradually loses its leaves, exposing slender
branches adorned with heavy crops of those spherical, greenish, bumpy fruits about the
size of cherries. The fruit's flesh isn't bad tasting but there are so many seeds that
it's hardly worth a human eating them. Animals, particularly livestock, just love them. In
many places it is the most abundant "weed tree." Cut or burn a field, let it
grow back, and the main tree appearing among the weeds will usually be this one.
THE FIG FAMILY, the Moraceae
Strangler Figs are such common, remarkable trees that we have a
special page here.
THE SOAPBERRY FAMILY, the Sapindaceae
Huaya is this tree's Maya name, and I can't find an
English name for it. It's Talisia olivaeformis. Its once-compound, somewhat
leathery leaves look like the leaves of North American ash trees, except that the leaves
arise singly at a twig node, not in twos, as among ashes. The tree grows naturally from
Mexico to Colombia, but is often planted in Central America for its edible fruit. The
fruit is yellow or brown, about an inch in diameter and a little longer than that, with a
large stone and thin, orange-colored, juicy pulp. Naturally wildlife loves the fruit, as
do certain people.
