3. stalk (PO:0025066)

(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 which 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)

• 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 supporta an individual flower in an inflorescence that contains more than one flower (LC revised from R,E,E4th edition).

4. 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: 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(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:

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.

-currently is_a (an) organ
