Veins evident on both sides, veinlets 6-8 pairs per segment, basal acroscopic veinlet reaching bottom of sinus, basiscopic one reaching margin above sinus. Laminae somewhat leathery, deep green when dry; rachises and veins all with setae and short hairs abaxially, adaxial sides of costae subglabrous with dense appressed setae along grooves, elsewhere glabrous.
