8B3CFA62CC73FFA333DBF76A0223F8B4.taxon	distribution	Distribution and ecology and conservation status: — Psydrax cudalorensis was found growing in sacred groves of Cuddalore and Pudukkottai districts of Tamil Nadu, India. The forest type of these groves corresponds to Tropical Dry evergreen forest of 8 A and 7 C 1 described by Champion & Seth (1968). P. cudalorensis is associated with Garcinia spicata Hooker f. (1875: 486), Pterospermum suberifolium (L.) Willdenow (1800: 728), Lepisanthes tetraphylla Radlkofer (1878: 276), Syzygium cumini (L.) Skeels (1912: 25), Mallotus philippensis (Lam.) Müller Argoviensis (1865: 196) and Argyreia cymosa Sweet (1826: 289). The authors observed more than fifty mature individuals at this locality although the exact population size and its distribution range needs to be explored further.
