straight (ovule orientation)

Etymology
Etymology Information

'orthotropous' originates from New Latin, ultimately from Greek elements: 'orthos' meaning 'straight' and 'tropos' meaning 'turn' or 'direction'.

Historical Evolution

'orthotropous' was formed in Modern/New Latin (botanical coinage) from Greek roots 'orthos' + 'tropos' and then adopted into scientific English usage in the 19th century to describe ovule orientation.

Meaning Changes

Initially the roots literally conveyed 'straight-turn' or 'straight-direction'; in botanical usage this evolved to the specific sense 'straight (ovule orientation)' and is now a technical descriptive term.
