Glottiphyllum longum

Glottiphyllum longum can be distinguished from its relatives by the way that its flat, green, fleshy, tongue-shaped leaves are all born in two opposite rows (distichous), lying flat and mostly prostrate along the ground. The long leaves are distinctively strap-shaped, with rounded margins. Sometimes they are also mildly curved or upturned at the tips, but not hooked. The bladder cells at the leaf margins are oriented horizontally and not elongated. The fruits are born on long stalks. The seed capsules have 9 or more locules and persist on the stem for many years. The seeds are very small and smoothed on the sides. Some of the information in this description has been found at desert-tropicals.com, llifle.com and cactus-art.biz
