5-7-plinerved, midrib impressed above and prominently raised beneath, lateral
nerves impressed above but plane distally, raised and prominent beneath,

and marginally, sometimes marginally fimbriate; pedicel 4-14 mm long,
densely short-pilose, often fimbriate; bracteoles oblong, linear
or subulate, 2-4.5(-5) x ca. 1 mm, densely pubescent or only marginally
ciliate, marginally glandular-fimbriate, these rarely fusing distally.
