x " Asperugalium" was a genus of flowering plants in the Rubiaceae family but is no longer recognized.
 It has been sunk into synonymy with x "Galiasperula", which is an artificial hybrid of "Galium" and "Asperula".
Asperula arvensis, known as blue woodruff, is a species of flowering plant in the Rubiaceae family.
 It belongs to the genus "Asperula".
 It is native to most of Europe plus Algeria, Morocco, and southwest Asia from Turkey to Kyrgyzstan.
Asperula, commonly known as woodruff, is a genus of flowering plants in the Rubiaceae family.
 It contains about 195 species and has a wide distribution area from Europe, northern Africa, temperate and subtropicale Asia to Australasia.
Rubieae is a tribe of flowering plants in the Rubiaceae family and contains 969 species in 14 genera.
 The genus "Galium" is responsible for more than two thirds of the species in the tribe.
 The second largest genus is "Asperula", which contains about 200 species.
 Unlike the rest of the Rubiaceae family, the tribe contains predominantly perennial and annual herbs with pseudowhorls of leaves and leaflike stipules and is centered in temperate and tropical-mountain regions.
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.
The prickly deepsea skate, "Brochiraja asperula", is a skate of the genus "Brochiraja", found around New Zealand, at depths of from 200 to 1,300 m on the continental shelf.
 Their length is from 30 to 50 cm.
Scopulariopsis is a genus of anamorphic fungi that are saprobic and pathogenic to animals.
 The widespread genus contains 22 species.
 "Scopulariopsis" belongs to the group Hyphomycetes.
 These species are commonly found in soil, decaying wood, and various other plant and animal products.
 In indoor environment "Scopulariopsis" is found on dry walls, cellulose board, wallpaper, wood, and mattress dust.
 Species of "Scopulariopsis" have also been isolated from carpets, hospital floors, swimming pools, wooden food packing, shoes and wood pulp.
 "Scopulariopsis" species are sometimes encountered growing on meat in storage.
 Some of the common species are "S. brevicaulis", "S. brumptii", "S. candida" and "S. asperula".
× " Galiasperula is a monotypic genus of flowering plants in the Rubiaceae family.
 The genus contains only one species, i.e. Galiasperula ferdinandi-coburgii", which is a hybrid of "Asperula" and "Galium".
 It is found in Greece.
Calamus is a genus of the palm family Arecaceae.
 These are among several genera known as rattan palms.
 There are an estimated 400 species in this genus, all native to tropical and subtropical Asia, Africa, and Australia.
 They are mostly leaf-climbing lianas with slender, reedy stems.
 To aid scrambling some species have evolved hooks on the underside of the midrib, or more commonly by modified "pinnae" or tendrils in the form of stout, backward-pointing spines.
 These stems may grow to lengths of 200 metres.
Acarospora is a genus of lichenized fungi in the family Acarosporaceae.
 Most species in the genus are crustose lichens that grow on rocks in open and arid places all over the world.
 They may look like a cobblestone road or cracked up old paint, and are commonly called cobblestone lichens or cracked lichens.
 They usually grow on rock (are "saxicolous"), but some grow on soil (terricolous) or on other lichens.
 Some species in the genus are fungi that live as parasites on other lichens (lichenicolous fungi).
 "Acarospora" is a widely distributed genus, with about 128 species according to a 2008 estimate.
