Mel/vin

Partially documented

Also written as Melvin, mel/vin

Mel/vin is a garden name rather than a single : it points at the mother plants of one Los Angeles grower from the forum era, and covers at least two different plants — a that leans towards and sometimes growth, and a that often makes four-ribbed columns. from that garden went into other breeders' crosses, which is how the name spread. Because the label covers more than one plant, a sold as Mel/vin does not tell you which of them you have.Too little stands behind this for us to confirm it.

  • four-wind columns
  • monstrose tendency
  • cristate sectors
  • green to glaucous

Other TrichocereusInformal label: Shorthand or a describing label rather than a cultivar name. It does not promise one specific plant.

Of the 15 things this page says, 3 name who reports them and 12 are marked as something we cannot confirm. Where a line is not settled, it says so underneath.

what the record holds

No source in this library records a confirmed cross for Mel/vin, 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.

Not a but a garden label: the name points at the mother plants held by one grower, and pollen from that garden went into other people's hybrids.Too little stands behind this for us to confirm it.

The longer version

Species, as our sources record it: covers two plants: a pachanoi-type Trichocereus and a bridgesii-type one.Reported by one source, and not corroborated anywhere else.

It refers to specific mother plants kept in that grower's collection rather than to a single selected clone.Too little stands behind this for us to confirm it.

The grower known as Nitrogen used pollen out of that garden for hybrids, and a cross written as PC by Mel/vin is among those attributed to it.Too little stands behind this for us to confirm it.

One plant in circulation carries a label saying its seed was sown around 2014 or 2015 and came from Chris Reeb, who is reported to have described the cutting as a revert off a monstrose plant.Too little stands behind this for us to confirm it.

In a 2017 forum post the grower said the collection held pachanoi that leaned monstrose plus a bridgesii form of which roughly half the columns had four ribs, and that the bridgesii was the likelier source of the pollen sent on.Too little stands behind this for us to confirm it.

Where the name comes from

Skin
skin, pachanoi form: green through to glaucous.One source states this, and our house botanist has checked it. green to glaucous skin is the ordinary colour range for this form.
Ribs
ribs, bridgesii form: columns often carry a reduced rib count, frequently the four-rib "four winds" shape, with spines and areole spacing normal for the species.One source states this, and our house botanist has checked it. reduced rib counts, including four-ribbed columns, occur in this species with otherwise normal spines and areoles.
Growth habit
growth, pachanoi form: it tends towards monstrose growth and occasionally throws a cristate section while keeping its column shape.Too little stands behind this for us to confirm it.

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.Too little stands behind this for us to confirm it.Some growers guessed the clone CSD came from PC by Mel/vin seed; others on the wiki page correct that, saying CSD is SS02 by Juuls Giant. Our own notes record CSD only as an Australian seed-grown clone whose initials already have two competing explanations, so all of these accounts stay open.Reported, but not confirmed.The wiki page also carries unverified talk that this grower once tried to put a name on the PC clone. The timeline is debated: a 2014/2015 sowing date on one label sits awkwardly with the 2017 post in which the grower describes what was kept.Too little stands behind this for us to confirm it.
