Vernation

[citation needed] The term vernation is borrowed from New Latin vernatio, the act of being verdant or flourishing (vernare).

At this stage it is called a crozier (after the shepherd's crook) or fiddlehead (after the scrollwork at the top of a violin).

In the case of many fronds, long hairs or scales provide additional protection to the growing tips before they are fully uncoiled.

[2] Circinate vernation is also typical of the carnivorous plant family Droseraceae,[3] for example see this photo of  Drosera filiformis.

It is also seen in the related genera Drosophyllum and Triphyophyllum, and in the much more distantly related Byblis; however in these three genera, the leaves are coiled outwards towards the abaxial surface of the leaf (reverse circinate vernation): this appears to be unique to these three plants among the angiosperms.

This fern is producing a new frond by circinate vernation.
This hosta leaf is produced by convolute vernation .
These cycad leaves are produced by involute vernation .
