Cones are single-flowered, are located groups on 3 on very short legs, the average cone of each group is underdeveloped. Of scales linearly - awl-shaped, with one not clear vein, are gradually narrowed by Koloskovye in an awn together with which they are 20-25 mm of length; lower floral scales lantsetny, ostrosherokhovaty, with a little twisting rough awn of 20-30 mm of length.
