Their comment: is synonym to Tubercle

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:

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

diaspore

definition from Beentje (2010): reproductive portion of a plant, such as a seed, fruit or fragment of fruit, that is dispersed and may give rise to a new plant.

We could add this term as a kind of upper level bin term (similar to trichome)

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. Comment: Aids plant in climbing.

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

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