Descendants of leaf

Suggested changes to descendants of leaf

Some of the current part_of children of vascular leaf should probably be part_of leaf, plus a few other changes

current is_a children of leaf

• non-vascular leaf - ok as is

• vascular leaf - ok as is

• prophyll (PO:0009042; is_a phyllome) and scale leaf (PO:0006003; is_a phyllome) should be children of vascular leaf

• Need to add frond and needle as exact synonyms of vascular leaf

current part_of children of leaf

• leaf apex - ok as is

• leaf base - ok as is

• leaf epidermis - ok as is

• leaf endodermis -- I think there is never an endodermis in non-vascular leaves, so this should be part_of vascular leaf

current is_a children of vascular leaf

Is there heteroblasty in non-vascular leaves? do these terms apply?

• juvenile leaf

• transition leaf

• adult leaf

Do we want to keep these (as phenotype terms)? At one point we discussed getting rid of them?

• simple leaf

• compound leaf

Terms that are probably okay:

• rosette leaf - probably ok - Are there ever rosette's in bryophytes?

• cauline leaf - probably ok

• cotyledon - ok

• leaf spine - ok

• cigar leaf - ok
