Hi Cathy:
Bulbs of Rolf Fiedler are only smaller than most forms of
uniflorum in cultivation. The way in that offsets are produced in R. F. is
quite unique in that a long white horizontal stolon runs some distance from
the mother bulb; the tip of this stolon swells gradually until it becomes an
offset. By the end of the growing season the stolon dries off leaving the
offset at a distance from the mother. This fat, fleshy stem is probably a
RF offset not completely separated from the stolon. This may indicate those
bulbs are the real RF.
Bulbs of both Ipheions are NOT like Narcissus bulbs (which
could perhaps be described as "broader at the hips"). Instead, they are
"broader at the shoulders", that is they are narrower at the basal plate,
unlike most bulbs. This odd form is also found in corms of Galaxias.
Regards
Alberto
