From Kakster. One of two clones I received from him. "Seeds originally collected by the Nazi cactlogist Friedrich Ritter who explored remote and dangerous areas of South America, living with impoverished Indians and writing taxonomic descriptions of cacti. As a young man, he fled Mexico to avoid paying pickax-wielding workers when his family's silver mine ran out of silver. He returned to his Fatherland to enlist in the army during World War II. After the war, he wrote books on cactus and philosophy preaching ""the uselessness of sympathy"". He died in the Canary Islands."
