pirindë

noun. flower that opened and shut quickly with any change of light

A word in Definitive Linguistic Notes (DLN) from 1959 for a “flower that opened and shut quickly with any change of light” based on √PIRI “blink” and with variant forms pirinde and pirne (PE17/146). These flower names were part of an attempt by Tolkien to come up with a new etymology for S. alfirin after he decided that √LA was not a negative element, so that alfirin could no longer mean “immortelle”.
