[SANS] Sans. Nelsonii

I don't have any first hand information on this subject, but maybe I've
read the limited (alas, very limited) literature on this subject more
than some.  (Gee, this guy sure had a big head!!!).  So here goes.
1) On pg 44 of Juan C's book, he describes S.t 'Nelsoni' as dark green
with little or no banding and forming a stacking plant with a short
stem.  He indicates that it may be produced (often, not consistently
apparently) from leaves of S.t. laurenti 'Compacta' indicating that it's
truly a var of S.t.  He cautions not to confuse with the SPECIES Sans.
nelsoni, so clearly this expert is well familiar with the latter. No
mention is made of flowers of the S.t "Nelsoni'.
2) Swinbourne's "Sans in Cultivation in Australia" on pg 15 (and fig.
29) also describes S. 'Nelsoni' and also attributes it as a var of S.t.
and has a description similar to J.C. (actually, Swinbournes work
pre-dates that of Juan C.) except that he describes the plant form as a
rosette although leaf dimensions are much the same. He says that it's
not known to flower.
3) I have a plant which I picked up from a roadside vendor which very
much resembles Swinbourne's description (I have seen no other Sans with
such dark green leaves and mine has no sign of banding whatever), but I
have had it less than one year and it only has a single growth.
4) Concerning John Gamesby's original entry on this thread, Brown's 1915
monograph attributes S. subspicata to Baker 1889.  Was Horst Pfenning
around at that date?  This S. subspicata thing really seems to further
muddy the water!!  Also John, apart from mentioning that it was a large
clump, you did not give us anything else to go on.  A summary
description from you or Hermine would be appreciated so that others of
us can get a feel for the plant you have labelled as PF115 S. nelsoni.
5) It really would be appreciated if some of the experts on this list
would give the details on the S. nelsoni species so that we can be
further enlightened.
Cheers from very sunny, warm as usual, Trinidad.
George.
