Ulmus mexicana, the Mexican elm, is a large tree
Description
Ulmus mexicana is one of the tallest elm species, occasionally reaching a height of 84 m (276 ft), and a
Uses
Although much of its natural range is threatened by deforestation, the tree is singularly unpopular in the timber trade on account of its deeply fluted trunk, and thus not considered endangered. The timber is hard and heavy (Gs 0.55), but difficult to dry, and can warp badly. Moreover, its high silica content (0.35) damages tools. The wood is used for tools, furniture, and floors, whilst the foliage is commonly used as fodder for cattle. The tree is occasionally planted for shade or ornamentation.[2]
Etymology
In Costa Rica the Mexican elm is known as Tirrá; the neighbourhood (district) of Tirrases in Curridabat, San José, takes its name from the tree.
