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.

Revision as of 21:33, 14 April 2010

POC meeting, Webex Conference Call; Date: April 20th, 2010 10am (PDT)

Agenda:

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

1. Wrapping up the whorls:

A. whorled Phyllome structure:(See SF Tracker: whorl phyllome structure)

Proposed new def'n:: A collective plant structure that contains one or more whorled arrangements of phyllomes.

Children are androecium, calyx, corolla, epicalyx, gynoecium, leaf whorl, perianth and whorled tepal structure.


Note: Whorls that have been reduced to a single organ will be placed under 'plant organ'.



Item carried over from last week's agenda:


2. fruit (See SF Tracker: fruit)

Is a fruit an organ?

Current def'n: The seed-bearing structure in angiosperms, formed from the ovary after flowering.


proposed change: fruit is_a 'collective plant structure' and part_of infructescence. (CPS: a proper part of a plant and is composed of two or more organs and any associated portions of plant tissue).


3. Embryo (See SF Tracker: embryo) Def'n: A young sporophyte contained within a seed. [source: APWeb:Glossary, GR:pj]

-has no is_a parent, propose making it is_a whole plant?


1. stem (See SF Tracker stem)

Stem def'n: The axial system of plants that bears leaves and buds. [source: APWeb:Glossary]

Synonyms: cane, culm, stalk, trunk

Problem: Stem has no is_a parent- should be a collective plant structure?

OR if we make it a child of plant organ, then penduncle, pedicel and gynophore can be stalks.


2. stalk (See SF Tracker: stalk)

This was added as a new term at the Ithaca meeting on 12/2009, to cover a number of the terms lacking is_a parents.

def'n: An 
elongated, sub-cylindrical to cylindrical structure that supports another 
organ or regional part of an organ.

Proposed def'n: A cardinal organ part that is elongated and
 sub-cylindrical to cylindrical and supports an 
organ or another cardinal organ part.

-made a cardinal organ part (as per its definition) rather than an organ.

Proposed children of stalk: (Test: do all of these fit the definition?)

  • filament: The stalk of a stamen.(stamen:organ)
  • petiole: The stalk of a leaf. (leaf:organ)
  • petiolule: The stalk of a leaflet (leaflet:cardinal organ part)
  • funicle: The stalk which attaches the ovule to the
 placenta.(ovule: cardinal organ part)
  • gynophore: The stalk at the base of the ovary.

(ovary: cardinal organ part)
  • leaf rachis: That part of the main axis of a pinnate or more highly compound leaf, that bears leaflets or divisions of the axis.(leaf:organ) (See SF Tracker: leaf rachis)
  • peduncle: The stalk of an inflorescence; that part of
 the inflorescence below the first flower or inflorescence branch and above 
the last foliage leaf/pair of foliage leaves. (See SF Tracker: peduncle)

propose revised def'n: The stalk of an inflorescence or an individual flower (R, E, E 4th edition).

  • pedicel: Basal part of the ultimate branch of the inflorescence. [source: APWeb:Glossary]

(See SF Tracker: pedicel)

propose revised def'n: The stalk of an individual flower in an inflorescence that contains more than one flower (LC revised from R,E,E4th edition).

Note: We also have the term 'stem'. We need to decide if 'peduncle' and 'pedicel' fit better as stalk or stem.
