The green and soft-haired leaves, which are variable in shape, hairiness and type of peripheral teeth, are inverted lanceolate to oblong, flattened and are 2.3 to 6.5 × 1.5 to 3.2 centimeters in size. The upper third of the leaf is covered with 3 to 8 reddish teeth.

The inflorescence is up to 16 centimeters high and consists of 1 to 3 dichasias . The reddish inflorescence stalk has a diameter of 4 millimeters at the base. The flower stalk becomes 7 to 8 millimeters long. The green sepals are 6 × 5 millimeters and the orange-red corolla 12 to 16 millimeters in size. The flower tube is 15 × 9 millimeters in size. The bent-back corolla lobes are 10 millimeters long. The three stamens protrude up to 5 millimeters. The yellow anthers are flattened and 1.5 millimeters in size. The oblong nectar flakes are green and 1 × 2 millimeters in size.
