NOTES

Bazzania recurva is a very characteristic species with its densely imbricate, triangularly suborbicular, entire leaves, finely and evenly denticulate at margin and slightly recurved, somewhat cucullate at apex. Underleaves densely imbricate, strongly concave in centre with reflexed margin, more or less auriculate at base, in situ U shaped, flattened semicircular-reniform, wider than long. Distributed in tropical Southeast Asia ( Kitagawa 1979), also known from Vietnam ( Jovet-Ast & Tixier 1958) and nearest in Thailand ( Lai et al. 2008) and in Malaysia Chuah-Petiot (2011).
