rheotropismn.

Brit.

/ˌriːə(ʊ)ˈtrəʊpɪz(ə)m/, U.S.

/ˌriəˈtrɑˌpɪz(ə)m/

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: rheo- comb. form, tropism n.

Etymology: < rheo- comb. form + tropism n., after German Rheotropismus (B. Jönsson 1883, in Berichte der Deutschen Botanischen Gesellschaft 521).

Biology.

The orientation or movement of an organism in response to a current of water. Cf. rheotaxis n.
