Description

''Aloe kedongensis'' branches from the base to form thick clumps of stems, each up to 4 meters long, and either erect or sprawling on the ground. The slender leaves (60 cm long, 3.5 cm wide) are recurved and without any markings (though the leaves of very young plants often have occasional white blotches on them). The 50 cm tall inflorescence sometimes has a branch or two, with cylindrical racemes. The tubular flowers are red, 3–4 cm long, and born on 2–3 cm pedicels. The tips of the flower lobes curve outwards.
