Fields Pach

Well documented

Also written as Fields Garden Pachanoi, FGP

Fields Pach, also called Fields Garden or FGP, comes from the Field's Cactus and Succulent Garden, a historic Australian collection. Growers know it by its encased spines and wavy ribs, and compare it to Ogun and Anita rather than to the common it superficially resembles. Where it actually came from is contested: Ecuadorian aguacolla, T. riomizquensis and an old Fields label of brevispinus have all been proposed. As a parent it throws variable seedlings that often inherit a jagged sawtooth .Reported, but not confirmed.

what the record holds

No source in this library records a confirmed cross for Fields Pach, and no other entry here names it as a parent. What the record does hold is below.

That is the record, not an oversight: of the 749 names in this library, 693 have no recorded relation either. Most named clones were selected, cut and passed along without anyone writing down what they came out of. A parent goes in here when a source states it and never because a name looks like one — a wrong pedigree would travel further than a blank one, because pedigrees get copied.

If you know where it came from, tell us — a person reads everything before it appears.

Its own ancestry is debated rather than recorded. As a parent it is noted for throwing highly variable offspring and for passing on a jagged sawtooth rib.Too little stands behind this for us to confirm it.

The longer version

Its is disputed: some growers connect it to Ecuadorian aguacolla imports.Too little stands behind this for us to confirm it.

Others suggest historical ties to riomizquensis, or repeat lore tying it to the same original that PC came from.Reported, but not confirmed.

A further account has it labelled as bridgesii brevispinus within the Fields collection at one time.Reported, but not confirmed.

The collection itself is documented outside the community wiki. A specialist reference records that it was stocked from a 1935 South American collecting expedition, which Mr Field helped pay for by buying a share in it, and later from Friedrich Ritter's material. The garden afterwards passed to Robert Fields, and it no longer exists.Reported, but not confirmed.

Australia's national biodiversity index carries Trichocereus as an accepted genus, with no species concepts beneath it and no synonyms at all.Reported by one source, and not corroborated anywhere else.So an Australian clone has no herbarium or census record to be checked against, and an Australian origin recorded here will always rest on collections and growers rather than on an institution.Reported, but not confirmed.

Ribs
A wavy rib pattern is one of its two signature features.One source states this, and our house botanist has checked it. Undulating or wavy ribbing is a real and stable trait in some Trichocereus.
Spines
Encased spines are the other, and growers compare the combination to the clones Ogun and Anita.Too little stands behind this for us to confirm it.
Growth habit
Superficially PC-like to some eyes, but with more clearly defined pachanoi features.Too little stands behind this for us to confirm it.
Notes
As a breeding parent it gives hardy but highly variable seedlings and often passes on a jagged sawtooth rib.Too little stands behind this for us to confirm it.

What the sources say

At least four competing accounts of its lineage sit on the wiki page, none of them settled. Growers disagree over how close it really is to the PC clone, with experienced contributors pointing to clear morphological differences.Too little stands behind this for us to confirm it.
