Gnetophyta is a division of plants, grouped within the gymnosperms (which also includes conifers, cycads, and ginkgos), that consists of some 70 species across the three relict genera: "Gnetum" (family Gnetaceae), "Welwitschia" (family Welwitschiaceae), and "Ephedra" (family Ephedraceae).
 Fossilized pollen attributed to a close relative of "Ephedra" has been dated as far back as the Early Cretaceous.
 Though diverse and dominant in the Tertiary, only three families, each containing a single genus, are still alive today.
 The primary difference between gnetophytes and other gymnosperms is the presence of vessel elements, a system of conduits that transport water within the plant, similar to those found in flowering plants. Because of this, gnetophytes were once thought to be the closest gymnosperm relatives to flowering plants, but more recent molecular studies have largely disproven this hypothesis.
Colletia is a genus of flowering plants in the family Rhamnaceae, with 15 to 17 species of spiny shrubs. All species of this genus are native to southern South America.
 They are non-legume nitrogen fixers.
The Flora of the Australian Capital Territory are the plants that grow naturally in the Australian Capital Territory (ACT).
 The environments range from Alpine area on the higher mountains, sclerophyll forest, to woodland.
 Much of the ACT has been cleared for grazing, and is also burnt off by bushfires several times per century.
 The kinds of plants can be grouped into vascular plants that includes gymnosperms, and flowering plants, ferns, bryophytes, lichens, fungi, and freshwater algae.
 Four flowering plants are endemic to the ACT.
 Also several lichens are unique to the ACT, however as further study is undertaken they are likely to be found elsewhere too.
Lilium (members of which are true lilies) is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers.
 Lilies are a group of flowering plants which are important in culture and literature in much of the world.
 Most species are native to the temperate northern hemisphere, though their range extends into the northern subtropics.
 Many other plants have "lily" in their common name but are not related to true lilies.
Arnebia is a genus of flowering plants in the family Boraginaceae.
Chloranthaceae is a family of flowering plants (angiosperms), the only family in the order Chloranthales.
 It is not closely related to any other family of flowering plants, and is among the early-diverging lineages in the angiosperms.
 They are woody or weakly woody plants occurring in Southeast Asia, the Pacific, Madagascar, Central and South America, and the West Indies.
 The family consists of four extant genera, totalling about 77 known species according to Christenhusz and Byng in 2016.
 Some species are used in traditional medicine.
 The type genus is "Chloranthus".
Apiaceae or Umbelliferae, is a family of mostly aromatic flowering plants named after the type genus "Apium" and commonly known as the celery, carrot or parsley family.
 It is the 16th-largest family of flowering plants, with more than 3,700 species in 434 genera including such well-known and economically important plants such as angelica, anise, asafoetida, caraway, carrot, celery, chervil, coriander, cumin, dill, fennel, hemlock, lovage, cow parsley, parsley, parsnip, sea holly, giant hogweed and silphium (a plant whose identity is unclear and which may be extinct).
The dicotyledons, also known as dicots (or more rarely dicotyls), were one of the two groups into which all the flowering plants or angiosperms were formerly divided.
 The name refers to one of the typical characteristics of the group, namely that the seed has two embryonic leaves or cotyledons.
 There are around 200,000 species within this group.
 The other group of flowering plants were called monocotyledons or monocots, typically having one cotyledon.
 Historically, these two groups formed the two divisions of the flowering plants.
Psychotria is a genus of flowering plants in the Rubiaceae family.
 It contains around 1,850 species and is therefore one of the largest genera of flowering plants.
 The genus has a pantropical distribution and members of the genus are small understorey trees in tropical forests.
 Some species are endangered or facing extinction due to deforestation, especially species of central Africa and the Pacific.
Austrobaileyales is an order of flowering plants, consisting of about 100 species of woody plants growing as trees, shrubs and lianas.
 Perhaps the most familiar species is "Illicium verum", from which comes the spice star anise.
 The order belongs to the group of basal angiosperms, the ANA grade, which diverged earlier from the remaining flowering plants, and, as such, it is the extant group after the Amborellales and Nymphaeales, that is sister to all remaining extant angiosperms outside of the ANA grade.
 The order includes just three families of flowering plants, the Austrobaileyaceae, a monotypic family containing the sole genus, "Austrobaileya scandens", a woody liana, the Schisandraceae, a family of trees, shrubs, or lianas containing essential oils, and the Trimeniaceae, essential oil-bearing trees and lianas.
