"What I said was that the floral tube ends near the
pseudostem."

These structures are not related or connected, but this statement could be
misunderstood to imply that they are. The floral tube may be very close to
the pseudostem but it is not connected to it. In the case of Pamianthe the
inflorescence is inserted in the pseudostem (as in Worsleya also) but it is
a separate structure that makes its connection to the plant further below,
in the bulb itself. Other bulbs have a similar morphology but with the
inflorescence and pseudostem standing separately, e.g., some Scadoxus
species. It is called a "pseudostem" because it is actually leaf bases
formed together to function and look like a stem. In other words, a false
stem.
