what the record holds

No source in this library records a cross for Taquimbalensis. 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

A specialist reference gives the plant as a Bolivian columnar cactus from near Taquimbala in the Cochabamba department at about 2,800 metres, with eight or nine ribs, white felted and spines that come in bright brown and age to grey. That is a or two short of the roughly ten one grower reports, and it is not the red that same grower describes.Reported, but not confirmed.

A Californian nursery says plants have been sold under this name for decades by two named nurseries, probably out of one private collection, and that some of that material is now being re-sold under the near-identical spelling Tacaquirensis. It also holds a plant of its own under this name that it says is distinct from that widely distributed one.Too little stands behind this for us to confirm it.So at least two different plants travel under the word in one catalogue — which is the warning this entry and the Tacaquirensis entry both carry, seen from the shelf.Reported by one source, and not corroborated anywhere else.

Character

A bar is drawn only where one of the lines below states it — never from the species, never from a photograph.

  • slow and steady to fast grower: this one leans towards fast grower, read from the growth line below.

Ribs
Thick-stemmed with roughly ten ribs.One source states this, and our house botanist has checked it. A thick stem with about ten ribs sits comfortably in the genus's range.
Spines
New spines come in red from white tufted areoles, and one grower calls them genuinely dangerous.Reported, but not confirmed.
Growth habit
Grows fast, though not especially fat for a plant sold as a fat Trichocereus.Too little stands behind this for us to confirm it.
Flowers
Flowers every year without fail for one grower.Our house botanist's reading of this: A mature, well-grown Trichocereus flowering every season is entirely normal behaviour.
Notes
Seed is reported to come mostly true to the mother, and one test returned 85%.Too little stands behind this for us to confirm it.

What the sources say

Tacaquirensis also grows in this yard and has an entry of its own here. The current treatment carries this name as a subspecies of that one, so the two are close relatives under a single name rather than unrelated labels — and a buyer should still expect them to look different.Reported by one source, and not corroborated anywhere else.
