I originally wrote much of this file to help me understand many of the terms employed in Danser's Nepenthes monographs and Obermeyer's work on South African Drosera (both on the CP web site.) I have probably missed a few due to the sheer size of the works. If there any words you feel should be included or redefined (not necessarily from Danser or Obermeyer,) feel free to Email me at:
