Geum sunhangii D.G.Zhang, T.Deng, Z.Y.Lv & Z.M.Li
Geum sunhangii is a species in the Rosaceae family, native to South-Central China. It was described in 2020 and is named after botanist Hang Sun. The species is distinguished by its lyrate-pinnate radical leaves, nodding yellow flowers, and unique style morphology. It is most similar to G. aleppicum but differs in leaf shape, flower orientation, and style structure.
Description
Geum sunhangii has fascicled roots and erect stems 20–60 cm tall. Radical leaves are lyrate-pinnate with 2–4 pairs of leaflets, the terminal leaflet reniform, lobed, and irregularly serrate. Cauline leaves are ovate, herbaceous, and either entire or 3-lobed. Flowers are yellow, actinomorphic, and nodding, with imbricate petals and a corymb inflorescence. The style is curved at an obtuse or right angle at the joint, located at about 2/3 of the style apex. The infructescence is ovoid or ellipsoid, with hirtellous achenes. It differs from G. aleppicum by its entire or 3-lobed cauline leaves, reniform terminal leaflet, and distinct style morphology.
