There were only 1712, 1713, 1714, 1715, 1716, 1717 and 1718. They were collected (legally) by YuccaDo Nursery many many years ago. The people at YuccaDo knew they were Pings but not what kind so they just tagged them with numeric codes. Someone at YuccaDo knew someone at ABG and sent ABG a few of each and then the ABG crew passed them on to me for assistance identification. The only obvious one, when it flowered, was 1714 though I had a pretty good idea even before it flowered because cyclosecta has a very distinct rosette. The others I ID'd as bet I could, 1713 and 1717 were either esseriana or jauvamensis. To this day I have never met anyone who can tell those two species apart so that was the best I could do. 1715, I proposed was a natural hybrid of 1714 and 1717. This was later supported when a cyclosecta x esseriana hybrid was man-made and it looked near identical. 1712, 1716 and 1718 are probably variants of moranensis.
