phyllode

Last week, we looked at examples of leaves where the petiole is a phyllode, but there is lamina development (with leaflets) beyond the lamina. In this case, the phyllode only represents the petiole portion of the leaf. We need a term to describe this, as well as when the whole leaf develops as a phyllode. Revisit this next week.

Proposed def: A vascular leaf in which the laminar development is a median plane (perpendicular to the axis), rather than the more common state of in a transverse plane (tangent to the axis).

Comment: Lamina development in a phyllode may occur in the region of the leaf that would normally develop into a petiole. In some leaves, the petiole may twist giving the appearance that the lamina is a phyllode, but it is not.

Unifacial leaf as synonym? No- not the same, but similar development.

TraitNet requests:

corm

proposed def: A short, enlarged storage stem in which the internodes do not elongate. Comment: usually underground.

child of stem (PO:0009047).

podarium

Their comment: is synonym to tubercle (even though they define tubercle differently)

podarium (from Beentje 2010): (in cacti or other succulents) a modified leaf base functioning as the photosynthesising organ.

tubercle (from Beentje 2010): (in ball- or barrel- shaped cacti), cone-shaped protuberances that are elnarge modified leaf bases fused with adjacent stem tissue (tubercle has two other definitions as well).

proposed def: A modified leaf base

Comment: Functions as the photosynthesising organ in some cacti and other succulents.

pneumatophore

definition from Beentje (2010): erect (breathing) root protruding above the soil, encountered especially in mangroves

proposed def: A root that is erect and protrudes above the soil.

Comment: Pneumatophores are found in trees that live in flooded habitats such as mangroves. May provide oxygen to below ground roots growing in flooded soils.

tendril

Defintion from Beentje (2010): a slender, coiling structure derived from a branch, leaf or inflorescence and used for climbing.

tendrils can derived from multiple types of structures. Suggest we make separate terms:

branch tendril (child of branch): A branch that is slender and coiling. Comment: Aids plant in climbing.

leaf tendril (child of leaf): A leaf that is slender and coiling and lacks a lamina. Comment: Aids plant in climbing.

leaflet tendril (child of leaflet): A leaflet that is slender and coiling and lacks a lamina. Comment: Aids plant in climbing.

leaf apex tendril (child of leaf apex): A leaf apex that is slender and coiling. Comment: Found at the apex of a leaf lamina, but the leaf apex tendril is not laminar. Aids plant in climbing.

Can add other types of tendrils if they come up or users need them.

This is the way we defined spine (no parent class spine, only leaf spine and stipule spine with is_a relations to leaf and stipule).

Alternative is to create a parent 'tendril'(is_a plant structure) with children that are part_of the other structures:

tendril: A plant structure that is slender and coiling. Comment: Aids plant in climbing.

branch tendril is_a tendril part_of branch

leaf tendril is_a tendril part_of leaf

leaflet tendril is_a tendril part_of leaflet

leaf apex tendril is_a tendril part_of leaf apex

The part_of relations are technically correct (not proper part), but the problem is that according to the formal definitions, a leaflet tendril or a leaf apex tendril would be a leaf tendril as well.
