SS03

Partially documented

Also written as Ss03

SS03 is a Sacred Succulents accession, and the letters are the nursery's own initials — the same series that gives the hobby SS01 and SS02, both of which grow in this yard. It is distributed out of California as a knuthianus, and growers pick it out by its strong spines and the deep V-shaped notches cut between the . It is one of the few numbered names in this library where the number resolves to a real nursery record rather than to nothing at all.Reported by one source, and not corroborated anywhere else.

what the record holds

No source in this library records a cross for SS03. 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

Our own catalogue records SS01 and SS02 as original Sacred Succulents , which is what fixes the meaning of the prefix.Reported by one source, and not corroborated anywhere else.

A Californian nursery selling under this number says its own plants came from Sacred Succulents, and from a named private collection before that.Reported by 2 independent sources; we have not seen it ourselves.That is one step further back than any other source here goes on this number, and it is a seller's account of its own rather than a record of the accession.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.

  • Not documented yet.

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

  • Not documented yet.

Ribs
Deep V-shaped notches between the areoles, which is the feature growers use to spot it.Reported, but not confirmed.
Spines
Seven to nine radials up to about an inch, with one stout central running to about two inches.One source states this, and our house botanist has checked it. Radial and central spine counts and lengths in that range are typical for the genus.
Growth habit
Seedlings raised from its seed come up very spiny, with thin yellow spines.One source states this, and our house botanist has checked it. Thin yellow juvenile spines and heavy seedling spination are common in this group.

What the sources say

The community wiki's own page for this number is empty; everything above comes from outside it. It is filed as a knuthianus by the reference that documents it, while the nursery's own text has been quoted calling it a form of . Both readings are recorded and neither is picked.Reported, but not confirmed.Knuthianus is itself a name the current treatment folds into Trichocereus cuzcoensis, so the label places the plant without pinning it.Reported by one source, and not corroborated anywhere else.
