Albuca juncifolia is a plant of the genus Albuca in the family of asparagaceae (Asparagaceae). The specific epithet juncifolia is derived from the name of the genus Juncus and the Latin word folius for 'leafy'.
description
Albuca juncifolia grows individually or forms small groups by dividing. Their depressed-spherical, partially above-ground bulbs have a length of up to 4.5 centimeters and are 3 centimeters wide. The succulent , brownish green onion scales are dry gray-white. The fleshy, white roots have a diameter of up to 3 millimeters. The two to five leaves are ascending or spread out. They are linearly narrowed, succulent and appear round, but have strongly curled edges. Your leaf blade is 5.5 to 20 inches long and 1 to 5 millimeters wide. The base is flat and runny, the tip of the leaf pointed.
The one to two racemose inflorescences reach a length of up to 28 centimeters. The lower half of the flower stem is sterile and measures 3 millimeters in diameter at its base. The lower, lanceolate, pointed bracts are 25 millimeters long and 7 millimeters wide. They get narrower further up. The initially white bracts soon turn brown. The upright, up to 25 millimeters long flowers are petiolate. The flower stalk is up to 7 inches long. The tepals are yellow and have a broad green central stripe. The outer tepals are erect, elongated, ribbon-shaped and hood-like at their tip. They are 25 millimeters long and 7 millimeters wide. The inner tepals are elliptical-egg-shaped, boat-shaped, hood-shaped at the tip, and cut out and trimmed. They have a length of 2 millimeters and are also 7 millimeters wide. The white, 1.2 to 1.4 centimeters long stamens are flat and have a diameter of 3 millimeters at their base. The inner stamens are constricted at their base. The elongated, movable anthers are 3 millimeters long and 1.2 millimeters wide. Outer stamens and anthers are smaller. The blunt triangular ovary is 6 to 7 millimeters long. The prismatic, yellowish stylus is slightly widened towards the tip and has a length of 7 centimeters. The three-lobed scars are yellow. The flowering period is late spring.
