Albizzia julibriss leaf organs question
 

Dear all,

please don't beat me if the answer really may be found in textbooks, but so
far I could not get it. That's why I am addressing it to you. the experts!

Here is my question: Looking at the leaves of an Albizzia sp. (probably A.
julibrissin, though the flowers are completely white, it's also called
"sleeping tree" sice it folds the leaves at night), I noticed two organs on
each leaf (one at the beginning and and one at the end which are 1 to 3 mm
in diameter and of ellipsoid shape).

Could anyone please point me to a reference where I might find some clues
on the role of these organs? Screening standard text books on plant biology
and-physiology in the library did not yield any result; Albizzia just seems
to be the textbook example for sleeping trees ;-)

All input is welcome!

Albizzia julibriss leaf organs question
 

Hello,

Many members of the Mimosaceae (or Mimosoideae, if you put legumes in
one family), have glands on the leaves. If I recall correctly, n at
least some species, these function as nectaries to attract
pollinators.
