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.
