In biology, a lemma refers specifically to a part of grass florets. It is one of two bracts that protects the floret of grasses (lemma in A Dictionary of Biology).
The Lemma Explained
Here's a more detailed look at the lemma:
-
What it is: The lemma is a modified leaf, or bract, in grasses.
-
Its Function: It serves a protective role, shielding the delicate flower parts during development.
-
Location: The lemma sits beneath another bract called the palea.
-
Relationship with Palea: The lemma surrounds the palea, which is the second, smaller bract. Both contribute to enclosing the flower within.
| Feature | Description |
|---|---|
| Type | Bract (modified leaf) |
| Location | Base of the floret, beneath the palea |
| Function | Protection of the flower parts |
| Found in | Grasses (family Poaceae) |
| Relation to Palea | Larger bract that surrounds the palea |
Example
Imagine a grass seed head. Each small, individual unit that will eventually become a seed is called a floret. The lemma is one of the leaf-like structures wrapping around that potential seed, providing a shield from the elements.
