Ungernia and "basal plate stems".

Dear Jim and all,

An unusual thick "basal plate stem" occurs in Ledebouria viscosa.  And in
some L. socialis forms I've examined, as the "bulb scales" wither they
expose a thin rhizome-like stem which functions for rooting and for
production of some offset bulbils.  There appears to not be a plate-like
basal plate in L. socialis, at least in the forms I've dissected.  The
growing center is elongate like a regular stem, extending way into the
"bulb" of clasping succulent leaf bases.  If it doesn't have a basal plate
is it a bulb?
