Chan Chan

Partially documented

Also written as KK339

Chan Chan is a Karel Knize collection number, KK339, rather than a selected , and the community wiki classes it as from a locality it gives as Chan Chan, Ecuador. The important caveat is built into the numbering: Knize's codes generally marked a collection area or an order lot, not a single plant, so seedlings under this number differ from one another. Some seed sold as KK339 is reported to have grown into something else entirely.Reported, but not confirmed.

what the record holds

No source in this library records a cross for Chan Chan. Nobody names a mother or a father for it, and no other entry here names it as a parent.

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.

The longer version

Species, as our sources record it: classified as Trichocereus pachanoi under the collection number KK339.Reported, but not confirmed.

The material was collected and distributed by the Czech collector Karel Knize under the number KK339.

Knize's numbers generally marked a collection area or a seed lot rather than one specimen, so plants raised under this number vary a lot.Reported, but not confirmed.

Some seed sold under the number is reported to have produced plants that do not match the pachanoi description at all.Reported, but not confirmed.

Both the community wiki and the specialist reference place the collection in Ecuador, and both have Karel Knize distributing it under the KK prefix.Reported, but not confirmed.The country is theirs rather than ours: it is one of the details this library's sources do not all agree on, so it is reported as what they say and not asserted here.Reported by one source, and not corroborated anywhere else.

The number refers to an area Knize mapped rather than to a single plant, so anything labelled KK339 comes from that population.

One contributor explains that plants under this number are all pachanoi because pachanoi was the only Trichocereus in the mapped area.Too little stands behind this for us to confirm it.

The wiki page separates it from Ritter's FR567, which covers T. knuthianus from Peru.Too little stands behind this for us to confirm it.

Where the name comes from

Notes
The wiki page records no count, spine measurement or colour, noting only the general association with Ecuadorian pachanoi forms.Too little stands behind this for us to confirm it.Plants show the usual Ecuadorian pachanoi look: green to faintly blue skin, short spines, and clear notches above the .One source states this, and our house botanist has checked it. Green to slightly blue skin, short spines and notches above the areoles is the standard pachanoi look.

What the sources say

Growers disagree about what Knize numbers mean at all, with accounts variously treating them as localities, elevations or order lots. Because the number covers seed rather than one clone, two plants labelled KK339 need not match.Too little stands behind this for us to confirm it.The community wiki files this collection twice, once under the locality name and once under the number. The two pages agree on the substance.Reported, but not confirmed.A field-number database compiled from collectors' own lists holds the same number under the same collector and the same species, and gives it an altitude of 2000 metres.Reported by one source, and not corroborated anywhere else.
