|winter rain climate
Gladiolus arcuatus Klatt grows in the dry western part of the winter rainfall area of South Africa. In Namaqualand this species grows among low shrubs in granite derived gravel and in fine grained silt in areas to the south. It has flowers that are dull grey purple, brownish or dark purple, with the lower three tepals yellow in the lower two thirds with the distal third dark purple fading to light grey purple. The dorsal tepal is largest, horizontal and arching forward. Flowers are very fragrant and probably pollinated by long tongued bees. The first photo below could be this species. It was seen in early September 2006 in Namaqualand in the right habitat. The second photo taken earlier that year was taken at Rod and Rachel Saunders' property at Brackenfell. They often sprinkle seed about. I think it also could be this species. Photos 1-2 taken by Mary Sue Ittner. Photo #3 taken by Rod Saunders.
