Gladiolus quadrangulus (D.Delaroche) Barnard (syn. Ixia linearis, G. linearis, G. biflorus) is found in the southwestern Cape in sandy soil in seasonally wet, poorly drained and sometimes brackish habitat. Goldblatt & Manning report that it has been eliminated from most of its original range, and that "its long-term survival in the wild is unlikely." Fortunately, it is relatively easy to grow in cultivation, where it can be treated like a typical winter-growing Glad. It has pale pink, mauve or white flowers. The tepals have darker veins. It blooms late winter into spring. The shape of the flowers is reminiscent of an Ixia, and unlike most Gladiolus it does not produce nectar. Goldblatt & Manning speculate that it is adapted to pollination by pollen-eating insects. First photo by Alan Horstmann. Second photo by Michael Mace of a plant whose name tag was lost, but which is almost certainly G. quadrangulus. The final photo was taken by Rachel Saunders who photographed it in the wild.
