Azolla (commonly called mosquito fern, water fern, and fairy moss) is a genus of seven species of aquatic ferns in the family Salviniaceae. They are extremely reduced in form and specialized, having a significantly different appearance to other ferns and more resembling some mosses or even duckweeds. Azolla filiculoides is one of two fern species for which a reference genome has been published. It is believed that this genus grew so prolifically during the Eocene (and thus absorbed such a large amount of carbon) that it triggered a global cooling event that has lasted to the present. Azolla

Equisetum telmateia, the great horsetail, is a species of Equisetum (horsetail) native to Europe, western Asia and northwest Africa.

It is found in Bangladesh, Bhutan, India, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, also Thailand. It is threatened by habitat loss. The World List of Threatened Trees (Oldfield et al., 1998) listed Iran as one of the countries with a population of A. malaccensis. The exploratory 2002 CITES review confirmed that Iran has no record of the species. As a result, Iran is no longer considered as habitat

Honckenya peploides, the sea sandwort (UK) or seaside sandplant (Canada), is the only species in the genus Honckenya of the plant family Caryophyllaceae.

Common names include garland flower, ginger lily, and kahili ginger. Members of the genus

Andira is a genus of flowering plants in the legume family, Fabaceae. It is distributed in the tropical Americas, except for A. inermis, which also occurs in Africa. It was formerly assigned to the tribe Dalbergieae, but molecular phylogenetic studies in 2012 and 2013 placed it in a unique clade within subfamily Faboideae named the Andira clade. Compared to other Faboideae the genus has unusual systems of root nodules and fruits, which are drupes. In most species the fruits are dispersed by bats, and in some they are dispersed by rodents. They may also be dispersed on water. Plants of the

A. macrophylla belongs to the plant family Aristolochiaceae and is found primarily along the Cumberland Mountains and Blue Ridge Mountains in the eastern portion of the United States, as well as Ontario, Canada. This species of plant has received considerable attention in the past few decades for the discovery of a potent compound called aristolochic acid, which has been the focus of debate due its harmful side effects. Aside from its decorative qualities, owing to its large leaves
