Flashcards in angiosperm apomorphies Deck (28):
1

Monocot Apomorphies

1) sieve tube plastids with cuneate proteinaceous inclusions of the p2 type 2) Atactostele stem vasculature 3) Parallel venation (most) 4) Single cotyedon

2

Alismatales

Intravaginal Squamules (trichomes in the axils of sheathing leaves) - not an ap.

3

Asparagales

Seeds with seed coat containing black substance called phytomelan

4

Commelinids

Posses a class of organic acids (coumaric, diferulic, ferulic) that impregnate thecells and make them uv-fluorescent

5

Zingiberales

1) penni-parallel leaf venation 2) Supervolate ptyxis 3) diaphramed air chambers in stem and leaves

6

Eudicot Apomorphies

1) molecular data 2) tricolpate pollen

7

Caryophyllales

1) camphylotropus ovules and perispermous seeds 2) sieve tube plastids with protein crystalloid inclusions surrounded by preoteinaceous filaments 3) betalains (pigmented compounds replace anthoaganins)

8

Rosids

-Molecular data -Tend to have bitegmic, crassinucellate ovules

9

Myrtales

Inferior ovary with a hypanthium

10

Fagales

Most monoecious and wind pollinated

11

Brassicales

Glucosinolate secondary compounds

12

Malvaceae

most with lysigenous mucilage canals

13

Asterids

1) Iridoid compounds 2)sympetalous corollas 3) unitegmic tenuincellate ovules
