雙黃花堇菜名稱的由來有此一說:雙黃花是指一朵正常開花,和一朵閉鎖花。

The genus name Viola comes from the most common colour of this genus and the species epithet biflora means 2-flowered. Is there a mistake in nomenclature? Because most of violets have violet-coloured flowers, the genus name is accepted. But what about biflora, two-flowered? Yellow wood violet like quite many other members in this family produce two kinds of flowers: beautiful ‘basic’ flowers and more modest flowers that don’t open but self-fertilize. With the yellow wood violet there are quite often two such gleistogamous flowers down among leaves. That gives the reason for the epithet biflora.
