Cactaceae in herbarium Hi, I'm currently putting together an herbarium for an exam at university and tries to exsiccate an Opuntia sp. emptying it, filling it with salt, putting it under the press for a week and finally passing it for 12h in 96° ethanol. What do you think of the result? Do you have any tips for the future? Originally by u/Silpha_carinata on Reddit: https://tinyurl.com/27k3zsle
