Blades vertically attached, to 4 cm long, somewhat leathery or crisp when dried ( Fig.4D View FIG ); blade shape highly variable but mostly lanceolate to oblanceolate in vegetative branches ( Fig. 4C, D, G View FIG ), those in reproductive branches oblanceolate to obovate; apex often attenuate or acute, sometimes round or obtuse ( Fig. 4 View FIG E-G); base usually asymmetrically cuneate; margin serrate to biserrate, sometimes erose or repand; some blades in terminal portion of the axes with duplicated apices perpendicular to the surface, some appearing turbinarioid ( Fig. 4 View FIG C’; Fig. 4G View FIG : arrowhead); midrib thin, apparent from to 2/3 of the blade length, sometimes percurrent; cryptostomata embedded and randomly scattered on the surface of the blade; petiole short to 3 mm long, flattened or cylindrical, with occasional spine-like protrusions. Vesicles smooth, globose, to 5.4 mm in diameter, sometimes ribbed to mucronated or phyllocystic with few cryptostomata; stalks short, to 3 mm long ( Fig. 4D, F View FIG ).
