Danthonioideae Danthonioideae is a mainly southern hemisphere subfamily of grasses, containing the single tribe Danthonieae and three unplaced genera, with altogether roughly 300 species. It includes herbaceous to partially woody perennial or annual (less common) grasses that grow in open grasslands, shrublands, and woodlands. It belongs to the PACMAD clade of grasses, but unlike some other lineages in that clade, grasses in the Danthonioideae exclusively use the C photosynthetic pathway. Its sister group is the subfamily Chloridoideae.

Acrostichum Acrostichum is a fern genus in the Ceratopteridoideae subfamily of the Pteridaceae. It was one of the original pteridophyte genera delineated by Linnaeus. It was originally drawn very broadly, including all ferns that had sori apparently "acrostichoid", or distributed in a uniform mass across the back of the frond, rather than organized in discrete sori. This led Linnaeus to include such species as "Asplenium platyneuron" in the genus, because the specimen he received had sori so crowded that it appeared acrostichoid.

Ophioglossum Ophioglossum, the adder's-tongue ferns, is a genus of about 25–30 species of ferns in the family Ophioglossaceae, of the order Ophioglossales. The name "Ophioglossum" comes from the Greek, and means "snake-tongue".

Ecballium Ecballium is a genus of flowering plants in the family Cucurbitaceae containing a single species, Ecballium elaterium, also called the squirting cucumber or exploding cucumber (but not to be confused with "Cyclanthera explodens"). It gets its unusual name from the fact that, when ripe, it squirts a stream of mucilaginous liquid containing its seeds, which can be seen with the naked eye. It is thus considered to have rapid plant movement.

Isoetales Isoetales, formerly also written Isoëtales, is an order of plants in the class Isoetopsida. There are about 140-150 living species, all of which are classified in the genus "Isoetes" (quillworts), with a cosmopolitan distribution, but often scarce to rare. Living species are mostly aquatic or semi-aquatic, and are found in clear ponds and slowly moving streams. Each leaf is slender and broadens downward to a swollen base up to 5 mm wide where the leaves attach in clusters to a bulb-like, underground corm characteristic of most quillworts. This swollen base also contains male and female sporangia, protected by a thin, transparent covering (velum), which is used diagnostically to help identify quillwort species. Quillwort species are very difficult to distinguish by general appearance. The best way to identify them is by examining the megaspores under a microscope.

History of Pachypodium The history of the genus Pachypodium as a scientific classification began in 1830, when the genus was first used in a taxonomical system by John D. Lindley, who placed a single species, "P. tuberosum", in it. Lindley believed that this species was identical with one identified in 1781 as "Echites succulenta", which would make "Pachypodium" a taxonomical synonym of "Echites".

Epidendrum tridens Epidendrum tridens ("the three-toothed "Epidendrum"") is a terrestrial orchid closely allied to "E. nocturnum", of which it has often been considered a variety or synonym. For example, Reichenbach 1861 lists "Epidendrum tridens" as a synonym of "Epidendrum nocturnum" and "Epidendrum nocturnum" var. "latifolium" as a distinguishable variety of "Epidendrum nocturnum".

Epidendrum flexuosum Epidendrum flexuosum, a reed-stemmed "Epidendrum" common at mid-altitudes in Central America, is a species of orchid commonly called "Epidendrum imatophyllum". It grows exposed to intense sunlight in the forest canopy, particularly on "Guava" species. "E. flexuosum" bears non-resupinate lavender flowers on a congested raceme at the end of a long peduncle.
