Marathwada region comprising seven districts (7005Õ–7805ÕN & 1705Õ–2005ÕE) forms a part of the vast Deccan Plateau of Maharashtra, India. The plant wealth of the Marathwada region is known through publications of several researchers (Naik 1966, 1967, 1969, 1970, 1979, 1998; Lakshminarasimhan 1996; Almeida 1998, 2001, 2003, 2009; Singh & Karthikeyan 2000, 2001). Cooke (1958 a,b,c reprint edition) in his ÔFlora of Bombay PresidencyÕ had not included Marathwada region, as it was then under Hyderabad State.
Ramling Wildlife Sanctuary and the adjoining region comprises hills and hillocks which support rich tropical dry deciduous and scrub vegetation. During our floristic explorations, thirteen taxa of flowering plants were recorded which are new to the Marathwada region.
