Xylopia parvifolia (Wight) Hook. f. & Thoms. is reported for the first time for Eastern Ghats from Dindigul District.
During the recent botanical survey conducted along the hilly tracts of Dindigul District of Eastern Ghats, the authors have collected some interesting specimens of the family Annonaceae. After a critical study based on relevant literature, it has been identified and confirmed as Xylopia parvifolia (Wight) Hook. f. & Thoms.
In South India, the genus Xylopia L. is represented by only one species, Xylopia parvifolia; hitherto reported only from the Western Ghats of Tamil Nadu (Ramamurthy, 1983) and Kerala (Mitra, 1997). Though Madras Herbarium (MH) has collections from Alagar Hills of Eastern Ghats, this species has not been reported from Eastern Ghats in any of the previous publications (Kottaimuthu et al., 2008; Matthew, 1983; Pallithanam, 2001; Pullaiah, & Rao, 2002; Subramanyam & Henry, 1959). Hence, the present collection of this species is being reported here as a new record for Eastern Ghats. A brief description with a photograph is provided here to facilitate futue collection and easy identification of the taxa in the field.

Ecology: In Dindigul District, only very few individuals of Xylopia parvifolia is recorded from three hilly tracts viz., Alagar Hills, Karandamalai & Sirumalai. It is found in moist and shady localities near streamlets of moist deciduous forests. It is seen growing with trees like Alphonsea sclerocarpa Thwaites, Nothopegia beddomei Gamble, Artocarpus hirsutus Lam., Aphanamixis polystachya (Wall.) Parker and Lepisanthes senegalensis (Juss. ex Poir) Leenh.
