Grows in abundance on the sandy, sometimes overflowed, bank: 
of the tite opposite St. Louis, with other hybrid forms, 
and with V. stricta, V. urticefolia,and V. bracteosa. V. pani 
lata is very rare seek perhaps destroyed by the growing bush 
which now cover the formerly grassy spots. Nevertheless, | 
narrow leaves, deeper colored flowers, and persistent style, pro) 
sufficiently that V. paniculata is one of its parents. Flowers 
July and August.
