Gad is another ordinary common noun in Hebrew. It means 'good luck'. We all want as much of it as we can get. So it is not surprising that it became a proper noun, the name of some people, a tribe of Israel, and a god. The god Gad was not ordinarily identified with Baal.
There currently are five recognized species in the Series Hexagonae, as the Louisiana iris group within the Genus Iris is called. They are: I. brevicaulis, I. fulva, I. hexagona, I. giganticaerulea and I. nelsonii.
The Hexagonae series name is derived from the first Louisiana iris species to inhabit the series, Iris hexagona. The name Louisiana iris comes from the naturalist and artist John James Audubon. In the 1821, a Louisiana flag (Iris fulva) was painted by Joseph Mason, then Audubon added his pair of parula warblers.ris nelsonii, common name Abbeville Red or Super Fulva, was the most recently discovered and named Louisiana iris. In 1938, W. B. MacMillan discovered the plant species; in 1966 Randolph named the iris.
