Long spines

[PD.]

On a large Trich i obtained recently i noticed some very long spines in various spots the longest being 24mm. Is it common for T. pach to have some longer spines or is this another trich or hybrid?

[Gunter]

Some pachanoi like material like the Juuls Clone can do that.

I wonder what the parents of that plant are?

[PD.]

Thanks Archaea.

I have no idea about the background of the cactus, it came from a large collection. The people i got it from bought the house with all the cacti and have no idea where any of them were sourced. Judging from the size of some of the cacti it looks as though they have been there for some time.

I've not grown the Backeberg clone to maturity to know whether or not it displays longer spines, but my guess would be that it can under the right conditions.

Either way, that plant is as much a pachanoi as any I've seen. I'd be eager to see whether that one would produce viable seed if crossed with other pachanoi clones.

yeah, they do that quite frequently, after you have replanted a cutting.

i see it as a responce to having being cut.

it basicly means the cactus reverted back into a more juvenile form.

mature pedros hardly show there spines ever, but once rejuvinated will do so.

if you mistreat a pedro, say you just let a cutting sit for a long periode (or never repot a specimen in a tiny container) the tip will even show seedling spine formation again.
