Morphology
Although poorly documented, the morphological traits of Celtis excelsa resemble the typical architecture of the genus Celtis. This taxon develops bark that is often smooth or adorned with characteristic corky protuberances. The deciduous foliage consists of alternate leaves, asymmetrical at the base, with a particularly prominent network of veins.
Floral structures generally remain inconspicuous, apetalous, and adapted to wind pollination. Fruiting results in the formation of small spherical drupes containing a hard, rough endocarp that effectively protects the seed.
