seeds

[Kathleen Archer]

Colleagues,
Thanks to all who responded to my request for a good demo seed.  I received
several suggestions recommending pine seeds, which show a papery remnant of
the nucellus underneath the seed coat.  The seed of Ricinus was also
recommended as easy to dissect, and useful for revealing various structures
after staining the cut surface with fast green.  I appreciate your help!
