vỏ lụa
Definition
- Noun:
- Tegmen (Botany): The inner, thin, membranous layer of a seed coat, specifically the delicate inner integument that surrounds the embryo. It is often contrasted with the outer, harder seed coat (testa).

Advanced Usage
- In botanical descriptions, "vỏ lụa" is a precise term for the tegmen.

Notes
- "Vỏ lụa" is a compound noun where "vỏ" means "shell/peel" and "lụa" means "silk," poetically describing the layer's thin, smooth quality. It is primarily used in scientific or detailed descriptive contexts rather than everyday conversation.
