Introduction

The genus Cressa L. belonging to family Convolvulaceae comprises of 3 species in the world distributed in Americas, Africa, Asia and Australia (The Plant List, 2015). In India, it is represented by one species distributed in Andhra Pradesh, Bihar, Gujrat, Maharashtra, Rajasthan, Uttar Pradesh and West Bengal.

During a floristic survey of Ratlam district, Madhya Pradesh in November 2015, specimens of Cressa L. were collected from the wastelands of Kharsaud village. Cressa cretica L., which is hitherto unrecorded from Flora of Madhya Pradesh (Mudgal et al. 1997; Khanna et al. 2001; Jha, & Khanna, 2002; Kumar &Khanna, 1998; Khanna et al., 2009; Mujaffar, 2012; Mujaffar et al., 2013; Ray & Sainkhediya, 2014; Sahu et al., 2012; Sainkhediya & Ray, 2013; Sikarwar et al., 2010; Sinha & Shukla, 2007). The same has been reported here as a new record for the flora of Madhya Pradesh. A brief taxonomic description and other relevant details are provided in the present communication.
