Storage behaviour
intermediate
Temperature-sensitive. Ages faster; may last only five years at −20°C, so 5°C is recommended.
Whether a seed can be dried and frozen decides whether it can be banked at all — which is the first question a seed laboratory asks and one no identification tool usually answers.
Dormancy
No pre-treatment recorded.
Seeds of a similar size
An unknown seed of this size could be any of these. That is the practical value of a measured reference set: it says what a specimen might be confused with, and by how little.
