Having or being shaped like two forks; split or divided into two branches.
From Latin 'bifurcus' directly, with the suffix '-ous' (full of, having the quality of). This is a more formal or archaic alternative to the more common 'bifurcated'.
While 'bifurcated' is much more common today, 'bifurcous' is the more direct descendant from Latin and sounds delightfully old-fashioned—the kind of word a Victorian naturalist might use.
