Terminal weirdness

[trucha]

I want to also start a discussion on jointing and odd termination issues.

I'll start out with some extremes and deal with it more when I have time and a decent conection to upload a bunch more images

Cristation is the most extreme terminal weirdness I know of

The upper left is the pachanoi from Ecuador at the HBG

The right is a JuulXperuvianus from Sacred Succulents

The lower left is a photo by Evil Genius (who gave me permission to use this image) showing an unlabelled crest that MIGHT be a macrogonus crest. Note the occasional presence of tiny awlshaped solitary centrals and grey felting.

However this is pretty odd too.

This thing is a Harry Johnson collection he called aff. huanucoensis. That is about all that is known about it. I've not yet seen its flowers.

Normal tip is on the left but check out what is going on on the right. Pay particular attention to the constrictions, partial jointing, total jointing and odd scarring as well as that weird lack of effective areole separation that occurred at the apical meristem on the column on the left in the right hand image.

I will revisit this again with many more images taken of different plants. Some are posted here already.

Look also at the HBG macrogonus pictures I have posted under How to recognize a macrogonus for some more instances of jointing behavior and watch for constrictions, complete & partial jointing and that odd scarring.

Please add images of jointed cacti as this is going to get not just weird but interesting.

I have some ideas but far more questions than answers.

Dichotomous Bruce.

Re previous pages: I've cut up a McSausage that had terminated and there were no holes to be seen anywhere so it's not a factor in the termination.

That's awesome!

[Chiral]

sweet, I love morphing weird rib droppers and knobblers.

[Quill]

SB that is incredible. i would treasure that one

[Chiral]

Hopefully these two will do what yours has done SB.

about those trichs with holes

in them, looks a lot like under fed grafted crests.

often the insides of grafted trichs are hollow in the same manner, which is believed to be from under fertilizing. grafted crests grow so damn fast, they need the food, and are often hollow...which quite often leads to rot. i wonder how many "rot pockets" are actually started from hollow spots which become infected. i wonder if this is a similar thing? perhaps so much good light, warmth and water, but not enough nutrition?

here are some pics of a copiapoa crest doing this, note how it began to rot eventually.

before being cut, looks normal

after

here is a peyote growing from the vasc. core

[strangebrew]

The flesh of the sausage plant is spongy, particularly in the core but it's only noticable if you cut down lengthways through the middle. I haven't cut up enough different types to say if it's unique or not. It's possibly a characteristic of plants that tend to grow prostrate with age.

If you got a pocket near the skin surface I'm sure it could lead to rot.

Here's a weird loph that's been getting weirder....

Thanks for the info on the copiapoa crest Kada.

I lost a huge one just like that due to interior rot.

a fortotten cutting of the so called t.monstrose sp peru, which typically goes from regular to monstrose growth a few times each season

turned crest

[KanJe]

Kada, I feel your pain with that crest mate.

[san p]

heres some pics of my crested pachanoi with monstrose growth.have a few other pach crests that look like they might be putting out monstrose sections aswell, but only time will tell.

[DayLight]

t. pachanoi, american PC clone, this photo was taken just a few days ago

monstrose/cristate t. pachanoi (traded to me as t. peru but obviously not)

variegated lophophora williamsii just starting to show dichotomous growth(two headed, the meristem has split into two growing points)

cristate lophophora, maybe a diffusa

[san p]

nice crests!

apical pupping, as apposed to your one ace, I'm pretty sure this was the result of slicing to close to the meristem when making the graft. it took really well as the vascular bundle is at its thickest at the apex, looking more like a solid circle than a ring. the last pic is of the plant the graft came from.
