Corolla glabrous, 1.4-3 cm long, yellow, with a rather widely funnel-shaped concolorous tube; petals cuneate, obliquely subtruncate at the apex, rarely purple-margined beneath. Filaments shortly glandular-pilose, the shorter 2.5-5 mm, the longer 4.5-7.5 mm long, with rather prominent obtuse teeth, the longest slightly recurved at the apex.
