Be aware that there are many databases which list Knize numbers but omit many of Knize’s actual applications of those numbers.  Confusion is prevented by their recognition not their avoidance.


A great collection of collection numbers can be found at Ralph Martin website (the above list was assembled using data from there and from Ritter’s Kakteen in Sudamerika)
