Gladiolus engysiphon G.J.Lewis is found in clay and granitic loam in renosterveld and grassland in the Langeberg Center (Swellendam to Mossel Bay). Growing from 35 to 50 cm high, it flowers March to April. The cream flowers with red median streaks are arranged in a 2 to 6 flowered spike. Photos taken by Rogan Roth in the southern Cape in April 2021. He first thought it was Gladiolus bilineatus which has a similar flower, distribution, and flowering time in the autumn. Both are pollinated by a species of long-proboscid fly. According to John Manning the lowest leaf in Gladiolus bilineatus always develops a short, sword-shaped blade, whereas the leaf blades in Gladiolus engysiphon are either absent entirely or needle-like. The arrangement of the leaves and the diameter of the stem is also different in the two species.
