So here's a little riddle: which species name can be found across Nepenthes, Drosera and Pinguicula? - it also happens to be three species that I have in my collection. Still don't get it? Well... Say for example, 'gigantea'. There's Drosera gigantea and Pinguicula gigantea, but to the best of my knowledge, there's no Nepenthes gigantea (varietal names - like N. rafflessiana var. gigantea don't count!). There's only a few names that occur like that. I can only think of two so if you find a common one across all families, you have a pretty good chance of taking the gemmae. Don't bother to look in my growlist... hasn't been updated in ages.
The first person to guess correctly will get 6 different types of drosera gemmae of my own chosing. You can't ask for specific species or crosses - it'll be something I have lots of.
