saccate

Lip barely saccate below, tapering and its sides involute above; anther ovate, long-pointed, borne on the base of the very short column, which is continued above the stigma into a conspicuous tapering awl-shaped gland-bearing beak.

Lower lobe mostly saccate, more or less remote from the stem.

Subdichotomously branching; leaves dark olive-green, subimbricate, obliquely ovate, acute, entire or subrepand; lower lobe saccate, rather remote from the stem, not spurred as in the European form; underleaves roundish, serrate or entire; involucral leaves bifid, serrate; perianth triangular-obpyriform.

Antheridia solitary in the saccate bases of leaves, crowded in short spikes.

Spur none; the broadly gibbous somewhat saccate base wholly free from the ovary; flowers large for the genus, purple, unspotted, more expanding.
