Smallest Gladiola in the World

I read before in the internet and also saw some pictures that the Gladiola or Gladiolus that I have in the picture below is the smallest kind of gladiola in the world. I just forgot its exact name. I hope I can find it next time and share it here. I guess we are lucky to grow some in our garden. There hundreds of varieties of this kind of flower. We had some other kinds before but they did not grew back this year again. Probably they are rotten under the ground. here is a photo of this lovely flowers.
Gladiolus (from Latin, the diminutive of gladius, a sword) is a genus of perennial bulbous flowering plants in the iris family (Iridaceae). Sometimes called the sword lily, the most widely-used English common name for these plants is simply gladiolus (plural gladioli, gladioluses or sometimes gladiolas).

The genus is distributed in Mediterranean Europe, Asia, Tropical Africa and South Africa. However, the center of diversity of the genus is located in the Cape Floristic Region, where most species were discovered. As a matter of fact, 163 out of the 250 species of Gladiolus are from Southern africa. The genera Oenostachys, Homoglossum, Anomalesia and Acidanthera, traditionally considered independent entities, currently are included in Gladiolus.
