Seed reference record
Melicope nealae
Rutaceae · Endemic
Close-up
One seed, filling the frame, focus-stacked. This is where surface texture, hilum position and sculpturing are legible — the characters that separate close relatives.
Pair
Two seeds, usually showing different faces. Many seeds are flattened on one side where they pressed against a neighbour, and a single view hides that.
Cluster
Several seeds together at lower magnification. Shows the range of size and colour within one collection, which a single specimen never does.

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
- Fire/GA3

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.
