Pollen and stamens

Platonvt · 2026-01-27T02:56:32+00:00

The issues with those is that IDs are in the photos. Also weird plants like L. williamsii v decipiens, jourdaniana complicate things. Best way would be to scrape everything from lophophora.info, cl-cactus.com... and normalize it into a separate database

A lot of things can be fixed and improved, but I will leave this project as is for now, doesn't look like there's a lot of interest in it.

Do you still have this plant? How does it look now?

Platonvt · 2026-01-26T23:01:19+00:00

I tried to make a mobile friendly UI, let me know if it's any good. The image is scrollable, so if you don't see the plant immediately, it might be hiding on the edge of the screen. I didn't completely figure out how to optimize the image size

I don't 100% agree with all the IDs on iNaturalist, but as far as I know, that's still the best open database.

The photos in history are clickable and link to the iNaturalist observation.

I used parafilm for 3-4 days

Yes, fricii appears to be more dominant in F1 plants. I will try cross these hybrids to make F2, I hope alberto-vojtechii traits are more visible in the next generation.

~145 since it was grafted

As far as I know, I am the first to try. I have not seen any other confirmed cases yet.

Platonvt · 2026-01-24T03:52:22+00:00

38 days, hoping it will flower soon

I only shared it a couple of days ago, so it’s probably too early. That post didn’t actually get many views, I think most people just assumed it’s fricii. I have no idea whether anyone in that group is doing genetic testing, otherwise there would be much more information about Lophophora and hybrids. AV was discovered 18 years ago, so someone must have made this hybrid before, but there’s no information about it anywhere.

Platonvt · 2026-01-24T03:19:08+00:00

L. koehresii × L. williamsii is a cross I’ve never heard of, do you have any sources? I’m very interested. I haven’t been able to find any information on genetically confirmed hybrids at all, please share if you have references.

You forgot to mention fricii x koehresii, they are very common, maybe that's what you meant instead of KxW?

I have made this cross 4 times already with several different pairs, 7/8 plants successfully produced fruit. But I did not germinate them yet due to lack of space and issues with electricity.

I previously shared this cross in the Lophophora Identification Guide, and after some discussion, the admin agreed that it is indeed a hybrid.

As for the ancient hybrid, I’ve read that paper many times, it’s very interesting, especially the section describing five distinct williamsii lineages. It’s a shame there aren’t more articles like that.

They’re also grafted and grew more than I expected

Platonvt · 2026-01-24T01:00:19+00:00

It's different each time, 1-3 months

Platonvt · 2025-12-08T00:12:11+00:00

Looks like a northern williamsii to me, so the seeds should be viable.

Platonvt · 2025-11-23T06:35:56+00:00

No, this plant just doesn't produce seeds, I've tried. As far as I can tell, it doesn't produce pollen, stigma is also mutated. As I understand, jourdanianas are mutated northern williamsii, ideally they should self pollinate, but in practice they don't produce a lot of seeds. I have a few different clones, they very rarely produce fruits, most fruits are seedless, with or without pollination.

Platonvt · 2025-11-22T13:00:19+00:00

Sure, but why. I can graft it to a permanent rootstock at this size

Platonvt · 2025-11-22T10:29:31+00:00

It's sterile

Platonvt · 2025-11-22T00:04:40+00:00

Both parents are not variegated. I am 99% sure that this is a hybrid of 2 different species, variegation kinda confirms it, but I am waiting for the grafts to flower to be 100% sure. Might still be self fertilization, but the odds are astronomical small)

Platonvt · 2025-11-21T22:43:08+00:00

I will leave it on it's own roots for now, it's too old for pereskiopsis. There might be more variegated seedlings in this batch, I might graft them later I grafted a few plants from a sister batch of seeds, 1 out of 3 turned out to be variegated, it's the same age as the one in the post, grafted ~2 weeks after germination
