Secondary venation adaxially impressed, abaxially flush with the lamina to somewhat impressed (dry), conspicuous and apparently broad (ca. 1 mm) owing to pigment in the bordering lamina, forming mor-or-less well-defined interprimary collective veins at least in the outer part of the blade; posterior lobes 1/3-2/5 the length of the anterior, the inner sides very narrowly oblanceolate; posterior costae naked in the sinus for 4 mm to 1 cm, basally diverging at ca. 90-100° then somewhat to abruptly back-turned
