Bluebonnet (plant)

Species often called bluebonnets include:On March 7, 1901, "Lupinus subcarnosus" became the only species of bluebonnet recognized as the state flower of Texas; however, "Lupinus texensis" emerged as the favorite of most Texans. So, in 1971, the Texas Legislature made any similar species of "Lupinus" that could be found in Texas the state flower.
Texas dollar
The Texas dollar, informally named the "Texas redback", was the paper money of the Republic of Texas. The Texas dollar was issued between January 1839 and September 1840 by Mirabeau B. Lamar to minimize national debt during his Presidency of the Republic of Texas. The name "redback" comes from the reddish color of the back of the bills. Inflation, due mainly to overprinting, devalued the notes substantially, making 15 redbacks equal to one United States dollar. This debt of over $10 million was an important factor for annexation into the United States.
