SG01 Medusa seal. Plain ring: nothing here sets a rib count, a spine length or a growth form the ring can mark.

Peruvianus

SG01 Medusa

Partially documented

Also written as SG01

SG01 Medusa is a seedling selection pulled from about a thousand plants raised from Icaros DNA seed bought through eBay. Its is unusually well recorded for a young — seed source, selection and the grower who raised it are all named. What is missing is the plant itself: no count, spine or description has been documented, so the name currently promises genetics rather than a known look.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.

Only the seed side can be recorded: the batch this plant was picked from was raised from Icaros DNA seed, and because the Ikaros mother stands are wild plants pollinated in the open, no father is on record.Too little stands behind this for us to confirm it.

What the sources say

No source we have found argues about this name — nobody has written that it is confused with another plant, or that two growers mean different things by it. That is worth knowing in itself.
