arabidopsis anatomy - stomates

Mon Aug 5 12:55:42 EST 1996

While observing GUS staining in the leaves of arabidopsis we observed unusual
stomates at the tips of the leaves.  At each point 4-6 very large stomates are
grouped together with no epidermal cells between them.  These stomates are
approximately 1.5-2x larger than the stomates found on the general surface of
the leaf.  The stomates are seen both open and closed.

Has anyone observed this before?  Does anyone know of a function or reason for
this difference?
