Gahnia vitiensis subsp. kauaiensis

Cyperaceae · Endemic

Gahnia vitiensis subsp. kauaiensis seed, Close-up

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.

Gahnia vitiensis subsp. kauaiensis seed, Pair

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.

Gahnia vitiensis subsp. kauaiensis seed, Cluster

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

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.
