There seems to be two meanings for bracteoles in the botanical texts I
checked listing both and others just listing. There seems to be agreement
that bracteoles are "small bracts" but also they are "secondary bracts".
Bracteoles that I deal with are a secondary series of bracts and are at
least relatively smaller. I can't think of a case where there are bracteoles
but no bracts. In a umbellate flower arrange, the bracts subtend the point
where the pedicels join the stem (the valve covers mentioned in an earlier
e-mail) and the bracteoles are arise from the base of the pedicel of the
individual flowers such as what Robert is referring to in Hippeastrum. I
don't know about their presents in Allium either, but thin tissued
bracteoles tend to dry up fast as soon as the umbel expands- Could they be
"dissappearing" or shed? The easiest place to see all manner of bracteoles
and bracts is with the composite family Asteraceae, though it probably won't
help with finding the answer to the Allium question.
