The identity of Dactyloctenium scindicum Boiss. has been a subject of perpetual errors over past decades in two broad regions of India viz. Indo-Gangetic plain (Haryana, Uttar Pradesh and Bihar state) and parts of Peninsular India (Maharashtra and Madhya Pradesh states). Despite its common occurrence in Northwest India (Rajasthan and Gujarat), the boundaries of delimitation of the species have remained vague in many floristic accounts. In the present study, we address and clarify a long trend of misidentifications in species of Dactyloctenium Willd. and discuss the correct identity and distribution of D. scindicum in India. Lectotypification of the name D. scindicum is done to establish the identity. A key is given to identify the species occurring in India. The range of morphological variation within the D. aegyptium (L.) Willd. complex and the correct identity and occurrence of D. australe Steud. in India is also discussed.
