Large-flowered Hibiscus, Cotton Rose, or Wild Althaea. 
Hibiscus grandiflorus, Mich. FI. Amer. vol. ii. p. 46. Pursch, FI. Amer., p, 
455. — Monadelpiiia polyandria, Linn. — Malvaceae, Juss. 
This beautiful species of Hibiscus, which does not precisely agree with any 
that I have seen described, although it is probably the above, is characterized 
by its ovato-cordate, obtusely and irregularly serrated, acute, venous tough 
leaves, and its large rose-coloured flowers, which are deep red at the base, 
and streaked with the same colour. The corolla is about five inches in 
diameter, the anthers yellow. The stem and leaves are smooth. It grows 
in salt marshes, and by the edges of pools.
