Huperzia is a genus of lycophyte plants, sometimes known as the firmosses or fir clubmosses; the Flora of North America calls them gemma fir-mosses. This genus was originally included in the related genus Lycopodium, from which it differs in having undifferentiated sporangial leaves, and the sporangia not formed into apical cones. The common name firmoss, used for some of the north temperate species, refers to their superficial resemblance to branches of fir (Abies), a conifer. As of 2020, two very different circumscriptions of the genus were in use. In the Pteridophyte Phylogeny Group classification of 2016, Huperzia is one of three genera in the subfamily Huperzioideae of the family Lycopodiaceae. Most species in the subfamily are placed in the genus Phlegmariurus. Huperzia is left with about 25 species, although not all have been formally transferred to other genera. Other sources recognize only Huperzia, which then has about 340 species.
The Piperaceae, also known as the pepper family, are a large family of flowering plants. The group contains roughly 3,600 currently accepted species in 5 genera. The vast majority of peppers can be found within the two main genera: Piper and Peperomia.
Fallopia is a genus of about 12 species of flowering plants in the buckwheat family, often included in a wider treatment of the related genus Polygonum in the past, and previously including Reynoutria. The genus is native to temperate and subtropical regions of the Northern Hemisphere, but species have been introduced elsewhere. The genus includes species forming vines and shrubs.
The Chenopodioideae are a subfamily of the flowering plant family Amaranthaceae in the APG III system, which is largely based on molecular phylogeny, but were included - together with other subfamilies - in family Chenopodiaceae in the Cronquist system. Food species comprise Spinach, Good King Henry, several Chenopodium species, Orache, and Epazote.
The Gomphrenoideae are a subfamily of the Amaranthaceae.
Disocactus is a genus of epiphytic cacti in the tribe Hylocereeae found in Central America, the Caribbean and northern South America. It should not be confused with Discocactus, which is a different genus.
Bauhinia seleriana is a species of plant in the family Fabaceae. It is found from central and southern Mexico to Honduras.
Anemonoides is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are native to the temperate regions of the Northern Hemisphere, on the continents of North America, Europe, and Asia. The generic name Anemonoides means "anemone-like",, a reminder that many of the species were formerly included within the genus Anemone.
Lipandra polysperma, common name manyseed goosefoot, is the only species of the monotypic plant genus Lipandra from the subfamily Chenopodioideae of the family Amaranthaceae.
Amphipterygium is a small genus in the subfamily Anacardioideae of the cashew and sumac family Anacardiaceae.
Fallopia dumetorum is a species of flowering plant in the family Polygonaceae, native to temperate Eurasia.
Hypericum steyermarkii is a species of flowering plant in the genus Hypericum, and is the only species in Hypericum sect. Santomasia. The species is found in the Chiapas province of Mexico as well as in Guatemala. The species was named for the collector of its holotype, Julian Steyermark, an American botanist.
Palhinhaea is a genus of lycophytes in the family Lycopodiaceae. In the Pteridophyte Phylogeny Group classification of 2016, it is placed in the subfamily Lycopodielloideae. Some sources do not recognize the genus, sinking it into Lycopodiella. Palhinhaea species are widespread in the tropics and subtropics.
Austrolycopodium is a genus of lycophytes in the family Lycopodiaceae. In the Pteridophyte Phylogeny Group classification of 2016, it is placed in the subfamily Lycopodioideae. Some sources do not recognize the genus, sinking it into Lycopodium. Austrolycopodium species are mostly native to the temperate southern hemisphere.
Noccaea is a problematic genus of flowering plants in the family Brassicaceae, native to temperate areas of western North America, southern South America, northern Africa, Europe and Asia.
Morisonia is a genus of flowering plants in the family Capparaceae, found across the Americas from the United States to Argentina. It was recently enlarged with New World Capparis species due to existing taxonomic instability. They tend to be shrubs or small trees.
Anemonastrum is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are native to the temperate and subarctic regions of North America, Greenland, Europe, Asia, South America, and New Zealand. The generic name Anemonastrum means "somewhat like anemone", a reference to a genus of closely related plants. It differs from the genus Anemone in having a base chromosome number of x=7, as opposed to x=8.
Bakeridesia is a genus of flowering plants belonging to the family Malvaceae.
Conostegia is a genus of flowering plants belonging to the family Melastomataceae.
Coussapoa is a genus of flowering plants belonging to the family Urticaceae.
