Hi everyone, I'm Luca Marasso from Edolo, in the italian alps, I'm 20 years old and I'm studying botany at university. I have a collection of 1234 specimens of various species of cacti expecially from mexico (100 different species of mammillaria and others like astrophytum and turbinicarpus) and I entered this forum because my interest in mammillaria grew a lot by seeing the posts by Maurillio in an italian forum in which I write since 2020. I'm glad to be there with all you
