# plants
Plants are the [[eukaryotes]] that comprise the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll.[^1]
Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae.[^2]

## classification of plants
Plants are the [[eukaryotes]] that make up the **Plantae kingdom**.
| PLANTAE (kingdom) | Group | Notes |
| ---------------------------------------------------------------------------------------- | -------------------------------------------------------------------------- | ------------------------------ |
| **non-vascular plants** <br>(lack the vascular tissues to transport water and nutrients) | [[#Bryophyta (Division)]] <br>(no vascular system; reproduce with spores) | mosses and liverworts |
| | | |
| **vascular plants** | [[#Pteridophyta (Division)]]<br>(seedless plants; they use spores instead) | ferns, horsetails |
| | [[#Gymnospermae (Clade)]]<br>(seeds within cones) | gymnosperms (conifers) |
| | [[#Angiospermae (Clade)]]<br>(seeds within fruits) | angiosperms (flowering plants) |

#### *Agathis* (Genus)
Commonly known as **kauri** (plural: kauri[^5]) or **dammara**, *Agathis* is a genus of evergreen coniferous trees native to [[countries of the world#Australasia|Australasia]] and [[countries of the world#Southeast Asia|Southeast Asia]].[^6]
One particularly cool kauri fossil, found in 2019 in [[countries of the world#New Zealand|New Zealand]], has helped more precisely date the [[Earth#Laschamps excursion|Laschamps excursion]]:
[[The rings of a kauri tree fossil from New Zealand (found in 2019) exhibit the strongest radiocarbon signature dated to within the past 50,000 years. It is believed to be evidence of the Laschamps excursion.]][^7]

### Angiospermae (Clade)
#### classification of angiosperms
…classification of angiosperms gives me a migraine. For now, instead, let’s just go with: classification of angiosperms relevant to these notes.
| ANGIOSPERMAE (Group/Clade) | Clade | Order | Family | Subfamily | Genus | Species |
| -------------------------- | ---------------- | ------------------- | -------------------- | ---------------------------- | ----------------------------------------------- | ---------------------------------------------------- |

#### Eudicots (Clade)

##### *Artemisia* (Genus)
[[Mugwort is a common name for several species of aromatic flowering plants in the genus Artemisia.]][^8]
[[Mugwort is also known as Cronewort.]][^9]
[[Mugwort is said to have been used in Germanic solstice rites.]][^10]
###### *Artemisia argyi* (Chinese mugwort)
In East Asia the species *Artemisia argyi* is often called ‘Chinese mugwort’ in the context of [[human beings#Chinese medicine (traditional Chinese medicine; TCM)|traditional Chinese medicine]], Ngai Chou in Cantonese or àicǎo (艾草) for the whole plant in Mandarin, and àiyè (艾叶) for the leaf, which is used specifically in the practice of moxibustion. *Artemisia princeps* is a mugwort known in Korea as *ssuk* (쑥) and in Japan as *yomogi* (ヨモギ).[^11]

#### Monocots (Clade)
##### *Ophrys* (Genus)
###### *Ophrys apifera* (bee orchid)
[[Some orchids (Ophrys apifera) mimic the appearance of sexually-receptive female bees.]][^12]

## flora
Flora = all the plant life present in a specific time or region. Generally, but not always, the plant life indigenous to that region. The name comes from [[religion#Flora|Flora]], a Roman deity.[^13] (Corresponds to **funga** for [[fungi]] and **fauna** for [[molluscs]].)
