Ulmus szechuanica

Ulmus szechuanica is a small to medium-sized tree that grows in South-Central and Southeast China. The species was formally published in 1947 by Fang, who designated three syntypes for the name. These include W. P. Fang 19667 (mature leaves), W. P. Fang 13289 (fruiting), and S. S. Chien 5861 (flowering). According to the International Code of Nomenclature for algae, fungi, and plants (Turland et al. 2018), these are considered syntypes under Article 9.6. Although duplicate specimens at the SZ herbarium are reported to be more complete, no lectotype has been designated due to lack of examination of these materials. The species is commonly known as the Szechuan or red-fruited elm.
