The upright flowers are on bare or rarely long-haired, 1 to 4 millimeter long pedicels , which are clearly thickened under the flowers. The calyx tube is 0.1 to 0.3 millimeters long. The triangular-awl, long narrowed, bald or rarely long-haired calyx lobes have a length of 2 to 8 millimeters and are 1 to 1.5 millimeters wide. The pale to greenish yellow corolla tube is 8 to 1 millimeters long.
