Fields Lamprochlorus

Partially documented

Fields Lamprochlorus pairs a collection with a species , and only one half of that checks out. The Fields collection is real and documented — Ralph Fields' garden at Yarrawonga in Victoria, the same garden Yowie comes out of — and lamprochlorus is a published cactus name, carried in the standing index twice over. What nobody has written down is anything about this particular plant: no traits, no date, no account of who named it. So we can place the name and not the cactus.Reported, but not confirmed.

Other TrichocereusNamed clone: One original plant and every cutting taken from it, given a name by a grower.

Of the 7 things this page says, 2 name who reports them and 5 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 cross for Fields Lamprochlorus. 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

The collection itself is documented outside the community wiki. A specialist reference records that it was stocked from a 1935 South American collecting expedition, which Mr Field helped pay for by buying a share in it, and later from Friedrich Ritter's material. The garden afterwards passed to Robert Fields, and it no longer exists.Reported, but not confirmed.

Australia's national biodiversity index carries as an accepted genus, with no species concepts beneath it and no synonyms at all.Reported by one source, and not corroborated anywhere else.So an Australian has no herbarium or census record to be checked against, and an Australian origin recorded here will always rest on collections and growers rather than on an institution.Reported, but not confirmed.

Where the name comes from

What the sources say

A nomenclatural record carries a name and never an identification: the index confirms that lamprochlorus is a published epithet, not that this plant is that species.Reported, but not confirmed.
