Anomocytic Stomata
Definition
A stomatal type where the guard cells are surrounded by ordinary epidermal cells with no defined subsidiary cells. Found in Erythroxylum and useful in epidermal peel preparations for leaf identification.
- Defining trait
- No differentiated subsidiary cells around guard cells
- Also called
- Ranunculaceous type
- Found in
- Erythroxylum (coca) and other plant families
- Used in
- Epidermal peel microscopy for leaf identification
Common questions
Why does stomatal type matter for identifying controlled plant material?+
When a seized sample is fragmented, dried or powdered and lacks obvious morphology, the epidermal cell and stomatal pattern surviving in a peel preparation can still place the material within its family or genus under a microscope.
What distinguishes anomocytic stomata from other stomatal classification types?+
Other types such as paracytic or diacytic stomata have one or more subsidiary cells with a distinct shape or orientation next to the guard cells, whereas anomocytic stomata are surrounded only by ordinary, undifferentiated epidermal cells.
