Recurved, Retrorse, Reflexed/Refracted

I got out my terminology book (finally) which has images of all three terms. If I get time to find better images, or scan the book images which are good, I'll update them. At least this way I can find them again!

Recurved - curved backward like a bow.
Ex: The petals of this Lilium sp

Retrorse - directed or downward or backward
Ex: The hairs on the stem of this grass

Reflexed or Refracted - Bent backward or downward
Ex: The petals of this flower
