Right now tepal has no is_a parent. I suggest making it an is_a child of plant organ. This is where petal is.
PO:0009033 tepal: A perianth segment in a flower in which there are two whorls of such segments, but all are similar in appearance. [source: APWeb:Glossary]
petal, sepal, tepal should all be is_a PO:0006001 : phyllome
We need to rewrite this one. it has always bothered me. It would only apply to monocots as worded and not to Magnolia for example where the term has been used for 150 years at least. It needs to be more general and apply to both.
A perianth segment in a flower in which all segments are petaloid and similar in appearance.
Revised def'n: A phyllome that is part of a perianth in which all parts are similar in appearance.

Thsi is a very generic definition. Such a phyllome can be a sepal/petal/tepal. We need something that everyone including a 6th grader can understand and can distinguish.
Her's my suggestion: A phyllome that is part of a perianth in which all parts
are similar in appearance and are indistinguishable from either or both the petal and sepal.
When you have tepals then there are no petals or sepals. Usually tepals look like petals. Tepals are mutually exculusive of petals and sepals. So I would reword:
A phyllome that is part of a perianth in which all
parts are similar in appearance and are neither petals nor sepals.

At the POC conference call on 4-27-10, we agreed on a new definition for the existing term tepal: A phyllome that is part of a perianth in which all parts are similar in appearance and are neither petals nor sepals (See comment below from dws).
This item will be accepted and closed.
At the POC conf call 5-27-13, we decided to revise the definition slightly:
tepal (PO:0009033): A phyllome (PO:0006001) that is part of a perianth (PO:0009058) in which all parts are similar in appearance and it is not possible to distinguish between the petals (PO:0009032) or sepals (PO:0009031).
I think this works better than what we had and what I suggested two years ago.
Changed definition of tepal (PO:0009033): A phyllome (PO:0006001) that is part of a perianth (PO:0009058) where it is not possible to distinguish between the petals (PO:0009032) and sepals (PO:0009031).
Added comment to tepal (PO:0009033): There is no differentiation between the petals (PO:0009032) and the sepals (PO:0009031) in color, placement, and size.
Added example to tepal (PO:00251317) comment: (e.g. some species of Magnolia).
