Hybrid

Matucana × Macrogonus

Well documented

This is a seed-grown between a Matucana-area and Trichocereus , and it looks the part: heavy, thick-stemmed plants whose and spines sit halfway between the two parents. It reached the wider community around 2022 through one grower who sold and gave away pieces, and other growers raised plants from the same seed. Nobody has recorded who made the cross, and because it is seed-grown, plants under this name are siblings rather than one identical .Too little stands behind this for us to confirm it.

Every ring is that plant’s own seal, in its family’s colour — open one to keep going.

Each plant wears its own seal here, coloured by its family — so a cross shows which side brought what before you read a name. A dashed ring is a plant with no page here yet, and a wire is only ever drawn from a parent somebody wrote down. Children are worked out from the other entries rather than stored on this one, so recording a cross anywhere lights it up on both plants.

The line matters as much as the box. A dashed line is a cross we can report but cannot confirm. Every cross drawn here is at that weakest reading, which is the true state of this plant's record.

Drawn 3 generations each way. Everything our sources record for this plant is in the drawing; the family stops there, not the tree.

the community wiki writes crosses as mother × father, and members place the Matucana side of this one in the mountains north of Lima, which fits Matucana as the . The person who actually made the cross is not named.Too little stands behind this for us to confirm it.

The longer version

Species, as our sources record it: a Matucana-region Trichocereus crossed with Trichocereus macrogonus.Reported, but not confirmed.

Who bred the seed batch has never been confirmed on the wiki page.Too little stands behind this for us to confirm it.

Plants from this cross were spread around and made popular in the community by Chuck BoBuck Hillman III, trading as Cactus Chuck, from about 2022.Too little stands behind this for us to confirm it.

A Peruvian contributor places the Matucana parent line in the mountainous country north of Lima.Too little stands behind this for us to confirm it.

Other growers, Dominion Plants among them, have raised plants from the same seed crop.Too little stands behind this for us to confirm it.

Where the name comes from

Distributed around 2022 by a named grower, with the maternal line traced to mountains north of Lima.Reported, but not confirmed.

Character

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

nearly smooth to heavily spined: this one leans towards heavily spined, read from the spines line below.

Skin: Between the blue-green of the Matucana types and the look of macrogonus.One source states this, and our house botanist has checked it. Colouring between blue-green and glaucous is a normal range for these plants.skin and spines: both land between the blue-green, heavily ribbed Matucana peruvianus look and the glaucous, long-spined macrogonus look.One source states this, and our house botanist has checked it. Intermediate skin colour and spine length between two forms is unremarkable in this group.
Spines: Intermediate, with the long-spined macrogonus side showing through.Too little stands behind this for us to confirm it.
Growth habit: Robust and thick-stemmed.One source states this, and our house botanist has checked it. Robust, thick-stemmed growth is ordinary for the genus.Growers describe these as heavy, thick-stemmed plants that run larger than average.One source states this, and our house botanist has checked it. Heavy, thick stems running large are well within the size range Trichocereus shows.Grafting works particularly well on this cross and is recommended for small or damaged pieces.Too little stands behind this for us to confirm it.Some of the softer cuttings have spotted when kept humid without much airflow.One source states this, and our house botanist has checked it. Soft new growth held humid with poor airflow commonly spots; that is expected, not implausible.
Notes: Grafting is reported as especially effective for small or damaged cuttings of it, and soft cuttings spot easily in humid, badly ventilated conditions.One source states this, and our house botanist has checked it. Grafting rescues weak or small cuttings, and soft tissue does spot in still, humid air.

What the sources say

The wiki page carries a banner saying it was assembled by a bot from community chat and has not been checked by an editor. Our own notes already record this cross with the same 2022 distribution and the same Lima provenance, so the two sources line up; both leave the breeder unnamed.Too little stands behind this for us to confirm it.

Cultivar histories in this hobby are passed between growers; where sources disagree we say so rather than pick a side.

Learned from

Links go to the channel, the subreddit or the front page of a site — never to one video, one post or somebody else’s product page. Nothing above is copied from any of them: every entry is written fresh from a fact list, with the source recorded against each fact as it went in.

Written from scratch off a cited fact list, never copied. Learned from the sanpedrocact.us community wiki (CC BY-NC 4.0), @sanpedromastery6262 and @IMDAVESBUD on YouTube, r/sanpedrocactus and medicactus.com's buyer guides, then checked against university extension horticulture, botanical gardens, cactus and succulent societies and the published botanical record. I will not name a plant from a photograph.
