What is Mini African Violet?

These days I came to know about there is something called mini african violet and after doing a search this is what I found between the different classification of the african violet.
Standard African violets when mature, will exceed 8" in diameter. In practice, most grow to about 10-12". When grown for exhibition, they can exceed 18-24" across. We grow only those varieties that we deem superior to others in growth habit and bloom.

Miniature African violets When mature, miniatures grow to less than 6" in diameter, semiminis to less than 8". With proper culture, actual plant size can be much smaller in practice. Because these are small-growing plants and have small root systems, never use a pot bigger than 2 1/2" in diameter.

Trailing African violets Have a naturally crawling or spreading habit. They produce branches or "runners" which then often grow along the soil surface, rooting and branching as they grow. They can be grown either as ground-covers or as hanging plants. Though their leaf size will remain constant, the size of the plant is limited only by the grower. Care is identical to that of other violets.
Spreading plants that can be grown in baskets or as ground covers

Based on the above definition, now I know my plants is a Standard African violets that is easily available in the nursery.

Miniature and trailing African violet hybrids (All 'Rob's' varieties)are proven, show-quality plants that grow and bloom readily, even under less than ideal conditions. They are bred to shape nicely, bloom continually, and typically will have unusually colored and larger than average-size blooms. All do well under either artificial or natural light.

Here is a samples of the Rob's varieties that I found on the web - Mini African Violets:
