Fugacious (in American)

2. (Botany) falling soon after blooming, as some flowers

One of these plants was called Liriosphodelus phoeniceus and Lobel states that the names "Hemerocalis" and "Ephemerum" were commonly applied to this particular plant because of the fact that the fugacious flowers last for scarcely a day. Of the flower behavior of the other type mentioned under the name Liriosphodeluslit tens liliflorus, the Lemon Daylily of today, Lobel makes no mention.

In this way Masdevallia, Sobralia, and other fugacious flowers may be used for decorative purposes for two evenings at least, but in the absence of immersion they would wither in a very short time. O'Brien, James

Couple of more entries on Google.
