Among the diverse populations of the South American hackberry, Celtis tala f. obtusata stands out due to its distinctive foliar traits. This particular form is recognized by botanists for its blunt-tipped leaves, which differentiate it from the typical, more pointed foliage of the species. It forms an integral part of the native woodland ecosystems where it occurs, contributing significantly to the local biodiversity.
This taxon shares many general characteristics with the typical Celtis tala, growing as a deciduous shrub or small to medium-sized tree. The branches are often armed with stipular spines, providing protection against browsing herbivores. The leaves of Celtis tala f. obtusata are alternate and simple, but uniquely characterized by an obtuse or blunt apex. The fruit is a small, fleshy drupe that typically matures to a yellow or orange hue, containing a single hard pit.

Within its native range, this tree serves critical ecological functions rather than commercial purposes. The dense, spiny canopy provides excellent nesting sites and protective cover for various bird species. Furthermore, the fleshy drupes are a valuable food source for native avifauna and small mammals during the fruiting season.
The taxonomic designation as a 'forma' (f.) indicates that this plant occurs sporadically within populations of the typical species, representing a minor morphological variation rather than a distinct geographical race. The specific epithet obtusata is derived from Latin, directly referring to the blunted shape of its leaf tips.
