context: Title: Greatest Hits (Elton John album)
  Passage: Greatest Hits (often referred to as Elton John Greatest Hits in North America) is the eleventh official album release for Elton John, and the first compilation.  Released in November 1974, it spans the years 1970 to 1974, compiling ten of John's singles, with one track variation for releases in North America and for Europe and Australia.

  Title: Eryngium foetidum
  Passage: Eryngium foetidum is a tropical perennial herb in the family Apiaceae.  Its scientific Latin name literally translates as "foul-smelling thistle".  Common names include culantro ( or ), "shado beni", Mexican coriander and long coriander.  It is native to Mexico and South America, but is cultivated worldwide, sometimes being grown as an annual in temperate climates.  In the United States, where it is not well known outside Latino/Hispanic, Indo-Caribbean, and Caribbean communities, the common name "culantro" sometimes causes confusion with "cilantro", a common name for the leaves of "Coriandrum sativum" (also in Apiaceae), of which "culantro" is said to taste like a stronger version.
  Title: Centranthus
  Passage: Centranthus is a flowering plant genus comprising herbs and subshrubs native to Southern Europe.  It is in the Caprifoliaceae family.  There are about twelve species in the genus.  Some "Centranthus" are known as introduced species in other parts of the world, including "Centranthus ruber" in the western United States and "Centranthus macrosiphon" in Western Australia.
  Title: Coriandrum
  Passage: Coriandrum is a genus of herbs in the Apiaceae family containing the cultivated species "Coriandrum sativum" (coriander) and the wild species "Coriandrum tordylium".  The leaves and seeds of "Coriandrum sativum" are used in cooking.  The leaves are often referred to as cilantro in North America.
  Title: Lycopodiopsida
  Passage: Lycopodiopsida is a class of herbaceous vascular plants known as the clubmosses and firmosses.  They have dichotomously branching stems bearing simple leaves without ligules and reproduce by means of spores borne in sporangia at the bases of the leaves.  Traditionally, the group also included the spikemosses ("Selaginella" and relatives) and the quillworts ("Isoetes" and relatives) but because these groups have leaves with ligules and reproduce using spores of two different sizes both are now placed into another class, Isoetopsida that also includes the extinct Lepidodendrales.  These groups, together with the horsetails are often referred to informally as fern allies.
  Title: Sanicula graveolens
  Passage: Sanicula graveolens is a species of flowering plant in the parsley family known by the common names northern sanicle and Sierra blacksnakeroot.  It is native to western North America from British Columbia to Montana to California, and southern South America, including southern Chile.  Its habitat includes mountain slopes, forests, and woodlands on serpentine soils.  It is a perennial herb producing a slender, branching stem up to half a meter tall from a taproot, with leaves alternate.  The lowest leaves have long stalks and are often attached below ground.  The upper leaves are smaller, sparse and often sessile.  The leaves are compound, the blades each divided into three deeply lobed, toothed leaflets.  The herbage is green to purple-tinged to all purple in color.  The inflorescence is made up of one or more heads of bisexual and male-only flowers with tiny, curving, yellow petals.  Each head has an array of narrow, toothed bracts at its base.  The rounded fruits are a few millimeters long, covered in curving prickles, and borne in small clusters.
  Title: Coast Mountains
  Passage: The Coast Mountains are a major mountain range in the Pacific Coast Ranges of western North America, extending from southwestern Yukon through the Alaska Panhandle and virtually all of the Coast of British Columbia south to the Fraser River.  The mountain range's name derives from its proximity to the sea coast, and it is often referred to as the Coast Range.  The range includes volcanic and non-volcanic mountains and the extensive ice fields of the Pacific and Boundary Ranges, and the northern end of the volcanic system known as the Cascade Volcanoes.  The Coast Mountains are part of a larger mountain system called the Pacific Coast Ranges or the Pacific Mountain System, which includes the Cascade Range, the Insular Mountains, the Olympic Mountains, the Oregon Coast Range, the California Coast Ranges, the Saint Elias Mountains and the Chugach Mountains.  The Coast Mountains are also part of the American Cordilleraa Spanish term for an extensive chain of mountain rangesthat consists of an almost continuous sequence of mountain ranges that form the western backbone of North America, Central America, South America and Antarctica.
  Title: Asarum caudatum
  Passage: Asarum caudatum (British Columbia wild ginger, western wild ginger, or long-tailed wild ginger) is native to rich moist forests of western North America from British Columbia to California and as far east as western Montana.  It is an evergreen with flowers that develop from March to August.  The flowers are distinct, hirsute (hairy), cup-shaped, and brown-purple to green-yellow which terminate in three, long, gracefully curved lobes, often concealed by leaves.  The long rhizomes give rise to persistent reniform (kidney/heart shaped) leaves.  Leaves are found in colonies or clusters as the rhizome spreads, forming mats.  The leaves emit a ginger aroma when rubbed.
  Title: North American beaver
  Passage: The North American beaver ("Castor canadensis") is one of two extant beaver species.  It is native to North America and introduced to Patagonia in South America and some European countries (e.g. Finland).  In the United States and Canada, the species is often referred to simply as "beaver", though this causes some confusion because another distantly related rodent, "Aplodontia rufa", is often called the "mountain beaver".  Other vernacular names, including American beaver and Canadian beaver, distinguish this species from the other extant beaver species, "Castor fiber", which is native to Eurasia.  The North American beaver is an official animal symbol of Canada.
  Title: Pieris (plant)
  Passage: Pieris ( or ) is a genus of seven species of shrubs in the family Ericaceae, native to mountain regions of eastern and southern Asia, eastern North America and Cuba.  Known commonly in North America as andromedas or fetterbushes, they are broad-leaved evergreen shrubs growing to 1 - tall and 3 - wide.  The leaves are spirally arranged, often appearing to be in whorls at the end of each shoot with bare stretches of shoot below; they are lanceolate-ovate, 2 - long and 1.0 - broad, leathery textured, and with an entire or serrated margin.  The young leaves in spring are typically brightly coloured.  The flowers are bell-shaped, 5 - long, white or pink, and arranged in racemes 5 - long.  The fruit is a woody capsule which splits into five sections to release the numerous small seeds.
