description

The plants of the genus Dracophilus grow compact and become somewhat lawn-shaped with age. A branch bears six to eight thick, triangular-shaped leaves . Their keel and edges are rounded or toothed, their epidermis is smooth.

White to purple flowers stand above bracts . They have five sepals . The stamens initially form an upright cone, which later develops into a cylinder. The brown or orange-colored nectarium is designed as a ring.

The eight (rarely to 14) fächrigen to ten capsule fruits are flat at the top and a funnel shape at the base. Their compartments cover about two thirds of the capsule. They have wide, rectangular valve wings and no closure bodies. The swelling bars run almost parallel. The papillary, short pear-shaped seeds are brown and 0.6 to 0.8 millimeters long and 0.5 to 0.6 millimeters wide.
