Usage examples of ivies.

Soon the picture was filled with little Ivies, all making cheers: bronze, brass, or worse.

I noted many kinds, those huge and hooded and furled on long sticks, enclosing the springs of their own alertness, or drowsy and pouched, nocturnal orchids, vines and ivies, showering ferns, palms in their rectitude, or those murky and velvet, or redolent of the limpness of old summers, or pale as lizards.
