The Gladiolus book has a key for the former Homoglossums. I spoke to Dee Snijman at one of the IBSA Symposiums thanking her for the keys and she seemed amazed. "Do you use the keys she said?" I thought to myself that I try, but not always with confidence. Not including Namaqualand makes it a bit dicey, but here we go. This muddies the waters a bit. The upper lateral tepals are about as long to slightly longer than the dorsal: leaf blades oblong to oval in cross section, the margins and midribs thickened; corm tunics hard and more or less woody in texture, decaying into vertical segments from below (G. watsonius, G. teretifolius ) The upper lateral tepals somewhat shorter to less than half as long as the dorsal; leaf blades x-shaped in cross section, the margins and the edges of the midribs thickened; corm tunics cartilaginous to fairly soft in texture, decaying with age into fine vertical fibers (Quite a few including G. quadrangularis, G. priorii) So the corms could be helpful too. I think the upper tepals in your photos look about as long as the dorsal. Between the two: Upper and lower lateral tepals lanceolate, more than twice as long as wide; blade of the lowermost leaf linear (oblong in cross section, (1.5-)3-5 mm at the widest = G. watsonius Upper and lower lateral tepals ovate, as much as twice as long as wide; blade of the lowermost leaf oval in cross section, 1-2 mm at the widest = G. teretifolius I hope this helps.
