Editorial Note
We have published this stub genus article as part of a wider reorganisation of Sorbus sensu lato articles. This work will enable a new revision of Sorbus sensu stricto to commence in 2023 and bring the nomenclature of this complex group of plants up to date in line with modern treatments. We will revise this genus in full when funding becomes available; if you would like to support TSO by sponsoring this genus please contact the editors.
TC, September 2023.
A monospecific genus native to China. Differentiated from related genera by the combination of: paired superposed ovules set in two carpels, the styles joined at the base; the oblate or sub-globose fruit which is generally wider than long, rarely globose, and small (5–8 mm in diameter); the fruit has few lenticels, or sometimes none, and ripens to red; calyx deciduous, leaving a nearly closed pit at the top of the fruit; leaves tomentose beneath, sometimes rufous-hairy on the main veins below, with craspedodromus venation. Compared to Alniaria, the flowers have smaller rather incurved petals, while the oblate fruit, the superposed ovules, seed with an angled margin, and the craspedodromus venation distinguish it from Alniaria. (Rushforth 2018).
