NPC Pollen Classification System Explained by ahanab626 is a document available to read on EtoBox.
The NPC classification system for pollen and spores, proposed by G. Erdtman in 1969, categorizes them based on the Number, Position, and Characters of apertures. There are nine types based on the number of apertures, seven groups based on their position, and seven character types, each represented by a three-digit code. This system allows for precise identification and classification of pollen types using a combination of these attributes.
