Frary, S.C. (2023) Oenothera laciniata Hill (Onagraceae) Cutleaf Evening Primrose. Photographed in visible and ultraviolet light.

Collected 12 April 2023 in an open field near Richland-Chambers Lake, Eureka/Corsicana, Navarro County. Texas, USA. Voucher deposition: Botanical Research Institute of Texas Herbarium (BRIT), Fort Worth Botanic Garden, S. C. Frary [167].

Other Common Names:  Raimannia laciniata, Cut-leaved Evening Primrose

Comment: A tiny yellow flower which blooms at night and lasts for one day.  Pollinated by moths in the dark.  The yellow petals fade to white with time during the following daylight hours, then wilt to orange.   Onagraceae flowers have strong UV signatures, and this one is no exception.

All the evening primroses that I’ve seen are nice in UV. Good shot!

Their signatures are really interesting.. if the flower lasts the day, I'll shoot a stack to try to get it all in focus.  Had to work quickly last night as it was starting to close up.
