ANGIOSPERMS

Angiosperms are flowering plants. They are the largest and most diverse group within the Plantae kingdom, with over 300,000 known extant species. This page will go over some of the numerous families of angiosperms. You will likely see many plants you recognize in this list. Before we jump in, take a look at this phylogeny of flowering plants by so you can see how the major clades in discussion relate to each other

Please note that this is not a comprehensive list of all angiosperms, that would be sooooooo long! I included the most prominent families that are relevant both in taxonomy and in human cultivation, with a clear bias towards Floridian plants.

Note: this page has a lot of images, so sections are disabled by default. It is not reccomended to enable multiple sections over a cellular network.


ANITA grade

ANITA grade angiosperms are the most primitive angiosperms. They are of particular interest to plant taxonomists because they help us imagine the evolutionary transition between gymnosperms and angiosperms.

Name Common Name/Examples Notable feature(s)BotanyPhoto
AmborellaceaeAmborellaNew molecular data shows this may be the earliest angiosperm in evolutionary historyLeaves are two-ranked with distinctly rippled/serrated margins.
Contains only tracheids, vessels are absent.
Small white inflorescences

NymphaceaeWater LilliesAquatic plants with flat leaf blades floating on the surfacePlants aquatic, rhizomes anchored in muck in still water
Leaves margins entire
Flowers often showy, numerous parts, rising above surface of water
Our native water lily in Florida is the Spatterdock!

AustrobaileyalesStar AniseLack differentiation between inner and outer floral whorlsThis one ends in “ales” and not “aceae” because it is an order, not a family
Debated whether or not it has separate families inside, so the entire order is treated as one unit when discussing ANITA grade
Often beetle-pollinated

Magnoliids

The Magnoliids have evolved characteristics that are not present in the primitive ANITA grade flowers, but they are neither monocots nor dicots. The group can be categorized by trimerous flowers, pollen with one pore, and leaves with branching veins.

Monocots

With magnolids and ANITA grade out of the way, now we can focus on the two largest clades of flowering plants, monocots and dicots! If you don't know, "cot" is is short for "cotyledon" (i.e. an embryo leaf) so the main difference is, does the plant pop out of the ground with one leaf or two leaves? There are some other differences as well but the cotyledon is the main difference, and the one that these groups were named after
