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. M.
