dextrorse
/deks'trɔ:s/
Definition
- Adjective:
- Spiraling upward from left to right: Describes a helical growth pattern, typically of a plant part like a stem or tendril, that twists or climbs in a clockwise direction when viewed from the point of attachment or from below. This is a specific botanical term.
Usage and Examples
- Adjective:
- The botanist identified the plant by its dextrorse tendrils.
- Unlike the morning glory, which is dextrorse, the hop vine is sinistrorse, spiraling to the left.
Advanced Usage
- Technical Botanical Context: The term is almost exclusively used in scientific descriptions of plant morphology to describe the direction of twining, climbing, or coiling.
- The distinction between dextrorse and sinistrorse growth is important for plant identification.
Variants and Related Words
- Dextrorse is the standard adjective form. A less common variant is dextrorsal.
- Dextrorotation (n): In chemistry and physics, this refers to the property of rotating plane-polarized light to the right (clockwise). While related in its "rightward" meaning, it is a different scientific term.
- Sinistrorse (adj): The direct antonym, meaning spiraling upward from right to left (counter-clockwise).
Synonyms
- Right-handed: In a general, non-scientific context, this can describe a spiral turning to the right. However, dextrorse is the precise technical term in botany.
