Ceratophyllales ceratophyllaceae
Ceratophyllales:Ceratophyllaceae

-Submerged aquatic with many adaptations for this habitat

-Fossil record extends back to the early Cretaceous

-Phylogenetic position still uncertain, but clearly part of the early radiation of angiosperms above the ANITA grade


Ceratophyllum – Probably sister

to the eudicots

The most recent

molecular data

support this.


Ceratophyllales:

Ceratophyllaceae -

Eudicots tricolpates
Eudicots (tricolpates)

  • Monophyletic: tricolpate pollen, slender filaments in stamens*, and loss of ethereal oils

  • Ca. 125 million years old as a lineage

  • Ca. 75% of angiosperm diversity (at least 160,000 species)

  • Flower parts in whorls, with whorls alternating*

*also happened in monocots!

Core eudicots the caryophyllales
Core Eudicots:The Caryophyllales

  • Vessel elements with simple perforation plates

  • Anther wall development

  • Support mainly from molecular data

  • Two main clades: Core Caryophyllales and the non-core Caryophyllales

  • Evidence now supports placement sister to the Asterids; previously near base of core eudicots

  • 10,650 species in 30 families



One origin of carnivory there is another in the asterids
One Origin of Carnivory(there is another in the Asterids)

  • One clade of the non-core Caryophyllales evolved carnivory (lost in one of the families)

  • At least three mechanisms: snap-traps, pitchers, sticky glands

Non core caryophyllales polygonaceae the buckwheat or knotweed family
Non-core Caryophyllales:Polygonaceae(The Buckwheat or Knotweed Family)

  • Widely distributed, usually in temperate regions

  • Herbs, shrubs, trees, or vines

  • Diversity: Approx. 1,100 species in 43 genera

  • Flowers: Perianth of 4-6 petaloid (sepaloid) tepals; stamens 5-9; carpels 2-3 in superior ovary; fruit an achene or nutlet, often 3- angled, often associated with remaining perianth parts

  • Significant features: Presence of a sheathing stipule, the ocrea, at stem nodes (lost in Eriogonum); nodes often swollen; leaves usually alternate, simple and spirally arranged; flowers in fascicles, these variously arranged in inflorescences

  • Special uses: buckwheat (Fagopyrum) fruits used as food; rhubarb (Rheum) petioles and sorrel (Rumex) leaves used as vegetable; many weeds

  • Required family



Polygonaceae polygonum knotweeds
Polygonaceae: Polygonum (knotweeds)

-a number of species in this

genus are weedy


Polygonaceae: Persicaria (smartweeds)

-a number of these are

native to North American

prairies, found especially in

potholes and sloughs


Polygonaceae -

Eriogonum


Polygonaceae – Buckwheat (Fagopyrum)



Core caryophyllales
Core Caryophyllales

Demonstrated to be monophyletic based mainly on DNA data, but most also share the following derived characters:

  • Betalain pigments – Nitrogen-containing (alkaloidal) red and yellow pigments that replace the anthocyanin (phenolic) pigments found in most other land plants

  • Presence of perisperm in seeds – specialized diploid tissue derived from the megasporangium

  • Ovules campylotropous with ‘beaked’ integuments – inner integument extends beyond outer at micropyle

  • Placentation free-central to basal

  • Coiled or folded embryos in seeds

  • Uniseriate perianth – single whorl of tepals

  • Stamens maturing centrifugally – Innermost anthers mature first, progressively moving to outside of whorl

  • Special form of sieve tube plastids surrounded by proteinaceous filaments
