Description
Pteroceltis tatarinowii is a deciduous tree that can attain heights of 20–30 m. The bark is grayish-brown and becomes fissured with age. Leaves are opposite, simple, broadly ovate to elliptic, measuring 8–15 cm in length, with serrated margins and a glossy dark green adaxial surface. The leaf venation is pinnate with prominent secondary veins. The species produces small, wind‑dispersed fruits that are samara‑like, each bearing a single seed. Flowers are inconspicuous, apetalous, and appear in early spring before leaf out; they are monoecious, with separate male and female flowers on the same individual.
Distribution and Habitat
The species is native to eastern and southern China, with confirmed occurrences in the provinces of Hubei, Hunan, Sichuan, Guizhou, and Guangxi. It also extends into northern Vietnam. P. tatarinowii typically grows in riparian zones, river valleys, and moist, limestone‑derived soils at elevations ranging from 200 to 1,200 m. The tree prefers well‑drained, humus‑rich substrates and is often found in mixed broad‑leaf forest communities.
Ecology
As a component of riparian forest ecosystems, P. tatarinowii contributes to bank stabilization and provides habitat for various avian and insect species. Its wind‑dispersed samara fruits facilitate colonization of disturbed sites along waterways. The species is relatively shade‑tolerant in its juvenile stage but requires increased light for optimal growth upon reaching maturity.
Uses
The wood of P. tatarinowii is lightweight, relatively soft, and has been traditionally used for making plywood, furniture, and paper pulp. In some regions, the bark and leaves have been employed in folk medicine, although scientific validation of pharmacological properties is limited.
Conservation Status
The International Union for Conservation of Nature (IUCN) has not assessed Pteroceltis tatarinowii as of the latest available data. However, habitat loss due to river regulation, agricultural expansion, and urban development has been reported to affect local populations. Conservation measures focus on protecting riparian habitats and establishing ex situ seed collections.
