The leaves are in clusters and are linear-lanceolate, slightly bent back, narrowly tapered at the base and pointed towards the front. They are 11 to 26 mm long and 2 to 5.5 mm wide.
The flower stalks have a length of 0.5 to 3.5 mm, they are directed upwards. The calyx is bell-shaped and woolly hairy, it has a length of 9 to 14 mm and a diameter of 3 to 5 mm. The calyx consists of a 3 to 7 mm long calyx tube, the non-fused parts of the sepals form pointed, almost upright lobes that can be 4 to 7 mm long and 1.8 to 3.5 mm wide at the base. The crown is funnel-shaped and colored blue, 17 to 23 mm long, its diameter is 12 to 20 mm. The coronet is unclearly lobed, the petals are marked with notch-like spikes. The inside of the short corolla tube is hairy. The stamens are unequal in length, the longer ones measuring 11 to 14 mm, the shorter 1 to 11 mm. The stylus is 7 to 8.5 mm long.
