#: TL03_2006-02-01
Subject: Back-lighted cross
section of T.rivale seed
Submitter: John
Gyer
Discussion: I've just done a
series of sections and dissection of T.rivale seed. As this section
shows the suctorial cotyledon has rolled edges that when they come
above ground will unroll into the leaf-like cotyledon that has been
discussed occasionally on the list.

Subject: Side lighted cross
section Trillium rivale seed
Submitter: John
Gyer
Discussion: This is a side lighted
T.rivale that clearly shows the rolled edges on the suctorial cotyledon.
When the cotyledon emerges, these edges will unroll and expand to
give the leaf-like appearance reported for the first photosynthetic
organ of this species.

air bubble.
