Yes! This is what I consider true cardenasii and what reminds me of the bat wings! The berries are similar in size to eximium and habit is similar also.
The calyx on CAP1530 resembles cardenasii also. Purple and short teeth.
The 1530 is probably my favorite flower...well maybe just because I'm looking at it now.
But honestly,whatever it is,you will not find many if any chile flowers more beautiful. The white trim around the corolla is so unique.
As far as cardenasii,ulupica,large ulupica,etc... I have seen a lot of ulupica that I feel are interspecific hybrids....rocopicas or whatever you want to call them. All are very promiscuous for wilds. The one rocopica I have going this year is a dead ringer for what I have seen labeled "large ulupica" in some european groups. It is crazy because my berries are smaller than the fruit that the seeds are from.
Claudio has been growing this specific hybrid for 6 or 7 seasons and has seen variations in fruit size,corolla color,markings and shape. Even from isolated seed and cloned individuals. That doesn't rule out cross pollination in some instances because I'm sure it happens a lot,but it is interesting that it happened with pure seed.
What makes my head spin even more is I am watching the blossoms change on my plant as the season goes on. The flowers originally were dark violet with some nice colors inside,and they were opened up quite a bit. Now they are almost turning blue,no interior markings and are campanulate. Barely can see the anthers.
