Year: 2026

Type: article

Abstract: This paper describes a new species of the genus Euonymus from Guizhou Province in southwestern China, Euonymus maotaiensis . The new species is morphologically similar to E. chloranthoides but can be distinguished by several key characteristics: broadly lanceolate leaves (as opposed to elliptic to oblong-elliptic), longer petioles (5–12 mm vs. 1–2 mm), longer peduncles (4–9 cm vs. 1–2 cm), 4- or 5-merous flowers (vs. strictly 5-merous), suborbicular petals with the upper half completely recurved abaxially (vs. planar petals), and indehiscent, 4–5 shallowly sulcate capsules (vs. 5-lobed capsules dehiscent to near the midpoint). These morphological differences are further supported by molecular phylogenetic analyses.
