Definition of "contorted"

We called at some more places with farcical names, where the merry dance of death and trade goes on in a still and earthy atmosphere as of an overheated catacomb; all along the formless coast bordered by dangerous surf, as if Nature herself had tried to ward off intruders; in and out of rivers, streams of death in life, whose banks were rotting into mud, whose waters, thickened into slime, invaded the contorted mangroves, that seemed to writhe at us in the extremity of an impotent despair.
