(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.
current 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 it a child of cardinal organ part (as per its definition) rather than an organ.
Proposed children of stalk: (Test: do all of these fit the definition?)
- filament: A stalk that is part of a stamen.(stamen:organ)
- petiole: A stalk that is the basal part of a leaf. Supports the lamina. (leaf:organ)
- petiolule: A stalk that is the basal part of a leaflet. Supports the leaflet lamina. (leaflet:cardinal organ part)
- funicle: A stalk that attaches the ovule to the placenta.(ovule: cardinal organ part)
- gynophore: A stalk at the base of the ovary. (ovary: cardinal organ part)
- leaf rachis: (See SF Tracker: leaf rachis)
current def'n: That part of the main axis of a pinnate or more highly compound leaf, that bears leaflets or divisions of the axis.(leaf:organ). Proposed def.: A stalk that is the main axis of a pinnate compound leaf, that bears leaflets or divisions of the axis.
- peduncle: (peduncle)
current def'n: 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.
>>This should probably be is_a branch (secondary or higher order shoot axis)
proposed def'n: A branch of an inflorescence or an individual flower (R, E, E 4th edition).
- pedicel: (See SF Tracker: pedicel)
current def'n: Basal part of the ultimate branch of the inflorescence. [source: APWeb:Glossary]
>>This should probably be is_a branch (secondary or higher order shoot axis)
proposed def'n: A branch that supports an individual flower in an inflorescence that contains more than one flower (LC revised from R,E,E4th edition).
2. New is_a children of cardinal organ part (See SF Tracker: new is_a children of cardinal organ part)
- receptacle: (See SF Tracker: receptacle)
Current def'n: The region at end of pedicel or axis to which parts of flower are attached. [source: APWeb:Glossary, POC:curators].
proposed def'n: A cardinal organ part that is the region at the top of either a peduncle or a 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)
- hypanthium(See SF Tracker: hypanthium)
Current def'n: 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.
proposed def'n: A cup- or tube-like cardinal organ part, bearing perianth and stamens on its rim, so these arise above the base, and often above the top, of the ovary.
made part_of receptacle instead of part_of flower
- pulvinus: (See SF Tracker: pulvinus)
Current def'n: 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. [source: APWeb:Glossary]
-currently is_a (an) organ, should be cardinal organ part.
Proposed def: A cardinal organ part that consists of a swelling at the apex or base of a petiole, petiolule, leaf sheath, or branch.
Comments: Often glandular. Often in movement of a plant structure in response 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.
