). The land area is approximately 1000 ha and situated in the Kurunegala District, North Western Province (dry bioclimatic zone) of Sri Lanka. The mean annual rainfall varies between 1,000 and 1,500 mm, which is received mainly during the northeast monsoon (No-vember-February), but a lesser amount during the southwest monsoon (May-September). The mean annual temperature of the area is 29.2-30.5°C, and its elevational range is 120-550 m a.s.l. Based on our preliminary investigations (22 December 2019, 10 February 2020, and 16 August 2020),
