Oxalis corniculata L. (Oxalidaceae), an addition of an alien plant species to the flora of Ladakh, India

Oxalis corniculata L. is recorded for the first time from the Trans-Himalayan region of Ladakh. The plant species has a conspicuous stem, obcordate leaf blades, and umbellate inflorescence with yellow flowers and cylindrical or narrowly ovoid fruits. As the plant is known to spread rapidly, it may become an aggressive weed of agricultural crops in Ladakh in near future. The taxonomic description, photographs and distribution map of O. corniculata are provided to facilitate its field identification in the region.
