• Order: Rosales
• Family: Cannabaceae
• Genus: Cannabis

The genus Cannabis contains three species; C. sativa, C. indica, and C. ruderalis.

C. sativa is thought to be originally native to Central Asia.
It is a dioecious herb (produces separate male and female plants), and the plants tend to be 1-3 meters tall. The psychoactive chemical THC is present in most parts of the plant, but it is most highly concentrated in the sticky resin produced by glands at the base of trichomes that cover the leaves and bracts of the female flower head. These trichomes constitute the main ingredients in hashish.

It is one of the oldest cultivated plants, having been found in the earliest strata of many Eurasian habitation sites. This plant has a long history of use in folk medicine and apart from the components that may have medicinal value it also contains psychoactive compounds. The main psychoactive compound is tetrahydrocannabinol, that causes a state of relaxation, and euphoria.
Other effects include a facility for introspection and philosophical thinking, as well as mild anxiety or paranoia.

Carolus Linnaeus, or Carl von Linné, a Swedish naturalist-physician, offered the first comprehensive and scientific system of classification and nomenclature for plants in his book Species Plantarum, published in 1753.
He made the use of binomial nomenclature the norm for botanical and zoological taxonomy. Although other botanists had used binomials, Linnaeus was the first to employ the system consistently.

Species Plantarum is basically the starting point for current plant taxonomy, containing the first validly published names of plant species.

Myrciaria cauliflora
Known as Jabuticaba. Native to Southern Brazil.
The fruit of this tree grow directly from its trunk.
Looks so delicious. :D

It also seems to have as many as 17 anti-cancer compounds, including a unique one called jaboticabin.

Archaefructaceae has been proposed as a new basal angiosperm family of herbaceous aquatic plants.

Fossils found in the Yixian Formation, Liaoning, China are very well preserved and show fruiting axes. Archaefrutus liaoningensis has reproductive axes but lacks petals and sepals, and bears stamens in pairs below conduplicate carpels. This feature is lacking in other fossils reported to be earliest angiosperms.
This 125-million-year-old plant suggests that the forebears of flowering plants may have been aquatic, weedy herbs.

The Convolvulaceae are known as the morning glory family. Shown here is Ipomea purpurea and tricolor. Some species of the Convolvulaceae family contain ergoline alkaloids.
Seeds of morning glory have been known to cause hallucinations due to the ergot alkaline, D-lysergic acid amide. Studies relate the presence of these alkaloids to an infection by fungi related to the ergot fungi of the genus Claviceps. This finding suggests that at some point during the species’ evolution there occurred some type of symbiosis with clavicipataceous fungi.

A plant called Amborella trichopoda found only in the remote island of New Caledonia has turned into a key piece into unraveling the origins of flowering plants. Amborella descends from the common ancestor that lies directly between gymnosperms and all other
angiosperms.
