scop MA9

I received this as a scop FR991 labeled as MA9 quietly also known as the Yellow Prince 

Team Wachuma provides a great write up with some history of this plant here and its involvement as the father of King Tubby (MA9 x TJG)

This is one of those FR991 scops that has been around the US for decades, prior to the recent exponential growth of diversity  

likely known under other names, lately the NMCR cordobensis in particular looks quite similar and may well be the same cactus plant
