Storage behaviour
orthodox
Desiccation-tolerant. Can be dried below 12% moisture and stored at freezing temperatures.
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.
