I think it's safer to say that Leucojum vernum 'Gertrude Wister' is
multi-segmented, not double. It has extra segments inserted around the ovary
and as I understand it, occasionally has 'fused' flowers so that there is a
cleft through the united ovary, plus two sets of reproductive parts (rather
like Galanthus 'Mrs Thompson'). It was first written up in the RHS Journal
when it was a small, A5-sized volume, but as my copies are elsewhere I can't
immediately look it up.

In snowdrops there is a precise terminology to describe flower form, and
this should be extended to Leucojum and Acis  as more variation is
discovered in those genera. 'Double' implies extra segments in the centre of
the flower, creating a rosette. No doubles are yet known in Leucojum,
although multi-segmented flowers are not uncommon. One sometimes hears the
word double referring to two flowers on a scape, but this condition should
be known as 'twin-flowered.'

And for John Lonsdale, yes, bulbs from that source are 'Gertrude Wister'.
