Abstract:
... Correcting taxonomic misidentifications is crucial to ensuring the conservation and use of wild relatives in crop breeding programmes. Macrotyloma sar-garhwalensis R.D.Gaur & L.R.Dangwal, described as a new species from Uttarakhand (India) in 1997, is one such case of mistaken identity. Critical study of its protologue, type specimen, and field-grown plants indicated that this species was conspeci ...
