POC Conf. Call 5-11-10

POC meeting, Webex Conference Call; Date: May 11th, 2010 10am (PDT)

Acceptance of the minutes from last weeks meeting? All in favor?

Agenda:

Items carried over from last week's agenda:

4. More 'new is_a children of cardinal organ part' (See SF Tracker: new is_a children of cardinal organ part)

Several weeks ago, we created new children of cardinal organ part, from terms that had no is_a parent. We can deal with definitions and relationships of each term later, but for now we simply need to approve moving them to cardinal organ part.

Some of them can be dealt with later, but the terms listed here are a higher priority and/or can be dealt with very quickly. Many of the definitions need to be worked on at a future meeting. See Source Forge items for additional comments.

*receptacle: The region at end of pedicel or axis to which parts of flower are attached. [source: APWeb:Glossary, POC:curators]. (See SF Tracker: receptacle)

propose revised def'n: The region at the top of either the peduncle or pedicel where the floral appendages (for example, sepals, petals, stamens, and pistils) are attached.(Brooklyn Botanic Garden http://www.bbg.org/gar2/topics/botany/parts_flowers.html)

Comments: If both pedicel and peduncle is_a stalk, and stalk is_a 'cardinal organ part', then both pedicel and peduncle must be part of some organ for this to work.

*hypanthium- A cup- or tube-like structure bearing perianth and stamens on its rim, so these arise above the base, and often above the top, of the ovary of a flower. (See SF Tracker: hypanthium)

made part_of receptacle instead of part_of flower

*pulvinus:-A more or less abrupt swelling, especially at the apex or base of a petiole or leaf sheath, often glandular and/or being the place where a plant responds to touch, gravity or light, in panicoid grasses a swollen region in the stem above the intercalary meristem - such a definition would also include stems of Chloranthaceae, Acanthaceae, Caryophyllaceae, Amaranthaceae, etc., cf. articulation.
