Beaucarnea gracilis is a species of flowering plant in the Asparagaceae family. It is native to Puebla, and northern parts of Oaxaca, in Mexico, where it is endemic to the Tehuacán Valley matorral.[4][5] It grows primarily in the seasonally dry tropical biome.

It is an arborescent species, and plants can form large trees over time.[5][6] It has a stem that is basally enormously swollen and circular in cross-section, with modest branching, growing up to 12m tall.[7]

The specific name gracilis means thin, presumably referring to the leaves which, as in Beaucarnea recurvata, are long and thin (30-60cm long and 4-7mm wide), but in this species they are erect, very glaucous and with margins minutely but sharply roughened.[7]

As with many species of Beaucarnea, Beaucarnea gracilis has been placed in different genera, including Nolina (as Nolina gracilis),[8] and Dasylirion (as Dasylirion gracile);[9] but modern research supports Beaucarnea existing as a genus, with Beaucarnea gracilis accepted as a species of Beaucarnea.[10]
