Ungernia post script and question.

Hi Jim and all,

Thank to explain this! Now I understand the Latin description of the
bulbs
in the Flora Iranica: "Bulbus. in collum longum productis."
Now that makes sense.
Very interesting. The image of a 'bulb tree' look a good model
to understand certain aspect of what is a bulbous plant.

The only amaryllid I know with long basal plate is old Clivia.
But as it don't make real bulb, the look is different.

Last year, I was surprised because the basal plate of my Ismene
longipetala
was 1 or 1,5 cm long. But now I see that was not really long!
