Polystichum proliferum, commonly known as mother shield fern is an Australian endemic fern.
 The genus name Polystichum is derived from Greek "poly" - many, and "stichos -" rows referring to the many rows of sori.
 The species name is derived from Latin, "Proli" – offspring and "fer -" bearing referring to the proliferous buds, a prominent feature of the species.
Tillandsia xerographica is a species of bromeliad that is native to southern Mexico, El Salvador, Guatemala and Honduras.
 The name is derived from the Greek words ξηρός ("xeros"), meaning "dry," and γραφία ("graphia"), meaning "writing."
 It is included in "Tillandsia" subg.
 "Tillandsia".
Tillandsia schultzei is a species in the genus "Tillandsia".
 This species is native to Venezuela.
 The name of the species is given by Hermann August Theodor Harms.
 "Tillandsia schultzei" is an evergreen and the height of a perennial reach of 50 to 70 centimeters.
Polystichum californicum is a species of fern known by the common name California sword fern.
 It is native to western North America from British Columbia to California, where it occurs in the coastal mountain ranges and the Cascade Range through the Sierra Nevada.
 Its habitat includes forest understory and open rocky slopes.
 This fern produces several arching or erect leaves up to a meter long.
 Each lance-shaped leaf is made up of many sharp-toothed segments.
 The undersides bear rounded sori which contain the spores.
 This fern arose as a hybrid between other "Polystichum" species and readily forms hybrids of its own.
Polystichum aleuticum, the Aleutian holly fern or Aleutian shield fern, is an endangered species of the "Polystichum" genus and currently consisting of a small, vulnerable population endemic found only on Adak Island, Alaska, a remote island of the Aleutian Islands chain in the northern Pacific Ocean.
 In 1992, 112 specimens existed in the wild, and a recovery plan was implemented.
Tillandsia is a genus of around 650 species of evergreen, perennial flowering plants in the family Bromeliaceae, native to the forests, mountains and deserts of Central and South America, the southern United States and the West Indies.
 They have naturally been established in diverse environments such as equatorial tropical rain forests, high elevation Andes mountains, rock dwelling (saxicolous) regions, and Louisiana swamps, such as Spanish Moss ("T. usneoides"), a species that grows atop tree limbs.
 Airplant is a common name for plants in this genus.
 Most "Tillandsia" species are epiphytes – i.e. they normally grow without soil while attached to other plants.
 Some are aerophytes or "air plants", which have no roots and grow on shifting desert soil.
 Generally, the thinner-leafed varieties grow in rainy areas and the thick-leafed varieties in areas more subject to drought.
 Most species absorb moisture and nutrients through the leaves from rain, dew, dust, decaying leaves and insect matter, aided by structures called trichomes.
Polystichum imbricans is a species of fern known by the common names narrowleaf swordfern and imbricate sword fern.
 It is native to western North America from British Columbia to southern California, where it grows in rocky habitat in coastal and inland mountain ranges and foothills.
 This fern produces several erect linear or lance-shaped leaves up to 80 centimeters long.
 Each leaf is made up of many narrow, overlapping, sometimes twisting leaflets each 2 to 4 centimeters long.
 The leaflets have toothed edges.
 This fern readily forms hybrids, some of which are fertile and are considered separate species, such as "Polystichum californicum", its hybrid with "P. dudleyi".
Tillandsia landbeckii is a species in the genus "Tillandsia".
 This species is endemic to Peru and Chile.
 It is one of the species of "Tillandsia" known as aerophytes, that grow on shifting desert soil rather than attached to other plants.
Tillandsia jalisco-monticola is a species in the genus "Tillandsia".
 This species is endemic to the State of Jalisco, Mexico and its species name means "mountain dweller."
 Its small purple flowers are pollinated by hummingbirds and it has large red- to yellow-tinted bracts all year long.
Polystichum is a genus of about 260 species of ferns with a cosmopolitan distribution.
 The highest diversity is in eastern Asia, with about 120 species in China alone; the region from Mexico to Brazil has nearly 100 additional species; Africa (17 species), North America (15 species), and Europe (5 species) have much lower diversity.
 Polystichum species are terrestrial or rock-dwelling ferns of warm-temperate and montane-tropical regions (a few species grow in alpine regions).
