Index Seminum meaning in Latin "seed index", is a catalog of seeds of wild or cultivated plants offered free of charge or in exchange of seeds of equivalent value by botanical gardens or arboretums. It is published annually or biennially by these institutions, traditionally in A5 format (148 × 210 mm).
The male catkins are patterned green and brown, 5–10 centimetres (2.0–3.9 in) long when shedding pollen; the female catkins are green, 2–6 centimetres (0.79–2.36 in) long at pollination, maturing in early summer to bear 10–20 (50–80) capsules each containing numerous tiny seeds embedded in downy fluff. The fluff assists wind ...
Bigtooth aspens produce seeds from wind-pollinated flower clusters, known as catkins. The tree is dioecious, meaning that male and female flowers are on separate trees, which flower from mid-April to mid-May depending on the climate zone. The seed, a two-valved capsule, is distributed widely by the wind. Seed production begins around 10 years old.

The seeds of the poplar tree are easily dispersed by the wind, due to the fine hairs surrounding them. The flowers are mostly dioecious (rarely monoecious) and appear in early spring before the leaves. They are borne in long, drooping, sessile or pedunculate catkins produced from buds formed in the axils of the leaves from the previous year ...
The only known natural example of King's Lomatia (Lomatia tasmanica) found growing in the wild is a clonal colony in Tasmania estimated to be 43,600 years old. [1]A group of 47,000 Quaking Aspen (Populus tremuloides) trees (nicknamed "Pando") in the Wasatch Mountains, Utah, United States, has been shown to be a single clone connected by the root system.
