Youngia
''Youngia'' is a genus of Asian plants in the dandelion tribe within the sunflower family. There are several weed species in the genus including the endangered ''Youngia nilgiriensis'' from Sispara in southern India, and ''Youngia japonica'', which is also known as Japanese Hawkweed.〔(Flora of China Vol. 20-21 Page 252 黄鹌菜属 huang an cai shu ''Youngia'' Cassini )〕 ''Youngia'' was first described in 1831 by H. Cassini,〔(Cassini, Alexandre Henri Gabriel de. 1831. Annales des Sciences Naturelles (Paris) 23: 88-90 ) descriptions and commentary in French〕 and the genus was later united with ''Crepis''.〔Bentham & Hooker, Genera Plantarum 2 (1873): 514〕 Taxonomic and cytogenetic studies by E. B. Babcock and G. Ledyard Stebbins led to the reclassification of the genus in the 1930s.〔Babcock, E.B. and Stebbins, G.L. 1937. ''The genus Youngia''.
