Fourcadei geissorhiza is a plant from the family of the Iridaceae (Iridaceae).
description
They are 15 to 30 centimeters high, perennial, herbaceous plants . The brown, woody to paper-like tuber is almost spindle-shaped, has a diameter of 6 to 10 millimeters and has a multi-layered, concentric structure, but occasionally like a roof tile, probably as a result of displacements, as it disintegrates into pieces irregularly when it is touched from above or below. Pre-season tubers persist and collect below the youngest tuber.
The lower leaf is membranous and light to dark brown. The three to five mostly upright leaves are 3 to 6 (rarely 2) millimeters wide, cylindrical to approximately cylindrical due to the enlargement of the central rib and edge, therefore provided with four grooves. They are half as long to as long as the stems . The lowest two to four leaves are down-to-earth, the upper ones are attached to the stem, partially or completely divorced and the shortest.
The stem is upright, smooth, not branched or branched once or twice, on it is a partially divorced leaf and two to three completely divorced, dry bracts . The inflorescence is a single-flowered spike , the bracts are 16 to 30 (rarely from 12) millimeters long (the inner just as long or slightly shorter than the outer). The six-fold flowers are tray-shaped and pink to light purple.
The flower tube is 17 to 20 (rarely from 8) millimeters long and cylindrical, widening slightly towards the end, the bracts are 25 to 30 millimeters long, up to 11 millimeters wide and vice versa lanceolate. The stamens are 13 to 20 millimeters long and of the same construction, the anthers 10 to 12 millimeters long. The ovary is approximately 4 millimeters long, hanging the stylus is divided above the top of the dust bag, the individual branches are bent back.
Flowering time is from mid-January to early May.
