The leaves are 15 to 30 × 4 to 7 mm in size, they are two-veined, linear, have a serrated edge, are opposite and are reduced towards the top on the stem. They are as long as or longer than the internodes .
The flowers are perched and overlapping like roof tiles in a very dense, spike-shaped inflorescence that is shorter than the vegetative shoot. The flowers are each accompanied by two bracts , these are 8 to 18 × 4 mm long, linear, stiff haired on the edges and the central rib and enclose the calyx .
The calyx is ten-ribbed and 5 to 8 mm long. The calyx tube is 3 to 5 mm long and covered with five unequal calyx lobes. These are lanceolate, 2 to 3 mm long and thus shorter than the calyx tube.
