PostSubject: Inter-generic hybrids   Mon Jun 16, 2008 8:57 pm

Rather than continue on about inter-generic hybrids in the post below, i was quite interested in intergeneric hybrids a while back and would like to share. here are some i found with some net browsing:
i would like to point out although intergeneric hybrids involving seemingly unrelated plants are highly unlikely it is possible in some isolated instances. And as already pointed out Trichocereus x Echinopsis are not inter-generic hybrids as Trichocereus are now incorporated within Echinopsis. so any crosses of these are just intra-generic (i.e. within a genus)

the most famous must be the 'ferobergia' - Leuchtenbergia principis x Ferocactus sp.. Turns out the two are actually closely related:

http://www.cactus-art.biz/schede/FEROBERGIA/Ferobergia/Ferobergia/Ferobergia.htm
i have also seen pics of Leuchtenbergia x Thelocactus as well.

here is a supposed cross between a Toumeya papyracantha and an Echinocereus knippelianus:
if it is then its very remarkable, although it is not proven and does resemble, if anything, a monstrose mammillaria:
http://www.cactus-art.biz/schede/TOUMEYA/Toumeya_papyracantha_hybrid/Toumeya_x_knippelianus/Toumeya_papyracantha_x_Echinocereus_knippelianus.htm

lophophora x ariocarpus, 'Ariophora':
http://www.panarottocactus.net/phpBB2/viewtopic.php?t=69

some neat stuff here, including a Pilosocereus palmeri x Disocactus speciosus:
http://www.lapshin.org/cultivar/N36/rowley-e.htm
^^
this is about as far apart as i can find, so its possible to cross a diurnal flowering jungle epiphyte: http://betula.br.fgov.be/RESEARCH/COLLECTIONS/LIVING/LIVCOL/img_medium/6005000030303_19392203_m.jpg
with a nocturnal-flowering columnar:
http://www.kaktuszgyujtok.hu/wgdb_images/sajat_kepek_kep_514.jpg
very interesting.
there is also lophophora x turbinicarpus but this can be expected as the two are quite closely related.

i think its also worth noting that a chimera is not an intergeneric hybrid, rather, it is 'A plant that contains a mixture of tissues from two or more genetically different cells or tissues in the same part of a plant. it is the resultant of a graft where the stock and scion combine the genes of both parents and produce an offset exhibiting features of both parents.' eg.
+Ortegopuntia cv Percy:

Interesting thread lewis. I really like the look of that Ferobergia.

I have come across those Ariophora pics before, there are many who believe it to be a hoax or some such. I am undecided. Looks pretty good though.

I believe there is a lot of work to be done with these inter-generic hybrids. Though some of them just look damn ugly, it's still a very interesting subject.

Thanks for posting this.

Some good reading. I'm sus on that ariophora looks like a dehydrated lopho to me, especially considering the natural variance of the species.


Leuchtenbergia principis is an interesting one. Has also been crossed with Astrophytum I believe.

Do you know which species/s of Astro HN? Very interesting I look foward to doing some hydrid work with this Genus in the future.

asterias seems to be a versatile one for use in hybridisation.

also Harrisia jusbertii, the commonly used excellent grafting stock is regarded as being an inter-generic hybrid of Harrisia pomanensis and Echinopsis eyresii, or possible chimaera between the forementioned.

What I find interesting is the flowers of Digi, asterias and Leuch principis are extremely simmilar. I wonder if Leuch principis would cross with digi ?

well they both have the long tubercle thing going on. it really is worth a shot. i've heard of unsuccessful attempts. i think the resemblance may be just superficial, although Digitostigma caput-medusae is still quite new.

Graft the digi and take the pollen when it flowers. I reckon that would make for an amazing hybrid. Look foward to hearing about any results from these inter-generic hybrids. Like wise I will post any info that comes to me from my experiences though might be a few years off yet. Oh well I see this place lasting a while anyway.

yep. graft at germination, push it hard to flowering size and pollinate with Leuchtenbergia. could work.

Inter-generic hybrids are a really unexplored area. there are hundreds of potential ones awaiting the pollination brush. lets get to work next spring!
okay i'll admit my previous attempts to cross Gymnocalycium quehlianum and Coryphantha elephantidens v. sulcolanata (my avatar) didn't work but hey its worth a shot! Laughing

Well in the meantime i guess we have to keep this place going! Smile

During spring I managed to cross a Chamaecereus (Echinopsis) sylvestrii with a Lobivia minuta, I put the seed in and had one germinate. It'll be a few years before it flowers, hopefully I can keep it alive that long.

In my collection I have a Lobivia Echinopsis cross, bought as Lobiviopsis sp.
At work we had several Echinopsis x Trichos, which are great looking plants. I think they where T. scop x E. secular.

Looking back on this post, I realise that these plants are very closely related, some even considered to be within the same genus now.

^ Echinopsis got greedy and has now engulfed Trichocereus, Chamaecereus and Lobivia,
I wouldn't mind seeing the result of this chamaecereus silvestrii and lobivia minuta hybridisation prier, could be interesting. [img]https://illiweb.com/fa/i/smiles/icon_smile.gif[/img]

Hey Lewis,

That "Astrobergia" looks awesome. Are you sure that plant is the result of a Principis and Astro cross ? Looks like it could be a mutation much like the "Lotusland" ?

yes, it is a Leuchtenbergia x Astrophytum. its Chinese.
i don't know what astro species though, could even be A.ornatum?

The spines look very much Ornatum. How do you know its a cross ? Does it say it on the site ? I can't find it anywhere.

Shocked

Is this a confirmed inter-generic hybrid? Certainly looks the part.

Very interesting indeed!!! Thanks for posting.

Trig the bloke (Paul) who posted this is the real deal. One of the best hybriders in the world, I think he even has a few species named after him. As you said they certainly look the real deal.

yeah, it seems some of the best cacti in the world are in Italy.
Astrophytum asterias has also been crossed with Thelocactus setispinus with interesting results. it has remarkably astrophytum-like flowers.

on the topic of inter-generic crosses, here is a Ferobergia x Echinocactus grusonii!!:

http://thegardenforums.org/viewtopic.php?t=17564

so leuchtenbergia x ferocactus, then resultant 'ferobergia' x E.grusonii. Incredible!
