Abstract: Oxalis xishuiensis, a new species of Oxalidaceae from Danxia landforms of Xishui County, Guizhou, China, is described and illustrated. It is morphologically similar to O. wulingensis by the two lateral leaflets arranged at about 180° angle and oblong pink petals with lilac veins, but clearly differs from the latter by leaflets almost as long as wide, obliquely obcordate lateral leaflets, shorter peduncles, longer capsule (1.2–1.5 cm vs. 0.5–0.7 cm) and alveolate seeds.

Hybridization of Oxalis corniculata and O. dillenii in their non-native range https://phytokeys.pensoft.net/article/61031/ PhytoKeys 178: 17-30

DOI: 10.3897/phytokeys.178.61031

Authors: Quentin Groom, Sofie Meeus, Steven B. Janssens, Leen Leus, Ivan Hoste

Abstract: Many species have been introduced beyond their native ranges and many have become global weeds. Human mediated dispersal has removed the geographic isolation of these species, reversing millions of years of independent evolution. Examples are the Oxalis species in section Corniculatae where several species have become invasive. Here we characterize and formally describe a hybrid between O. dillenii and O. corniculata, which occurs spontaneously in Belgium and Japan. Oxalis corniculata is probably native to Japan, but both species are alien to Belgium and O. dillenii is native to North America. We formally name this hybrid as Oxalis × vanaelstii. Although this hybrid is sterile, it is nevertheless vigorous and perennial. Both parent species grow as weeds in gardens; therefore, it is likely to be more common than currently appreciated in countries where these species co-occur.

Typification of Oxalis bowiei W.T.Aiton ex G.Don (Oxalidaceae) https://phytokeys.pensoft.net/article/33280/ PhytoKeys 119: 23-30

DOI: 10.3897/phytokeys.119.33280

Authors: Quentin Groom

Abstract: Oxalis bowiei W.T.Aiton ex G.Don (Oxalidaceae) from South Africa was described in 1831, but has not been typified. Although no preserved material was mentioned in the original description, an illustration by Thomas Duncanson painted a few years earlier would have been available to W.T. Aiton at the time he described it and it matches his description. Therefore this illustration is designated as the lectotype for Oxalis bowiei.
