  Passage: Helianthemum , known as rock rose, sunrose, rushrose, or frostweed, is a genus of about 110 species of flowering plants in the family Cistaceae.  They are widely distributed throughout the Northern Hemisphere, especially in the Mediterranean.

  Title: Phemeranthus
  Passage: Phemeranthus (fameflower) is a genus of flowering plants in the miner's lettuce family, Montiaceae, native to the Americas.  It is sometimes placed in Portulacaceae.

The genus name refers to the African genus "Tritonia" and is combined with the Greek word "opsis", meaning "look-alike".
  Title: Cistaceae
  Passage: The Cistaceae are a small family of plants (rock-rose or rock rose family) known for their beautiful shrubs, which are profusely covered by flowers at the time of blossom.  This family consists of about 170(-200) species in nine genera that are not very distinct, distributed primarily in the temperate areas of Europe and the Mediterranean basin, but also found in North America; a limited number of species are found in South America.  Most Cistaceae are subshrubs and low shrubs, and some are herbaceous.  They prefer dry and sunny habitats.  Cistaceae grow well on poor soils, and many of them are cultivated in gardens.
  Title: Kukufeldia
  Passage: Kukufeldia is a genus of iguanodont dinosaur that existed in what is now England during the Early Cretaceous period.  Identified from a nearly complete right dentary (NHMUK 28660) found near Cuckfield and originally described in 1848 by Gideon Mantell, it was named by Andrew T. McDonald, Paul M. Barrett, and Sandra D. Chapman in 2010, and the type species is "Kukufeldia tilgatensis".  It was originally identified as "Iguanodon anglicus", but the authors consider this a "nomen dubium" of which the type specimen BMNH 2392, some teeth found at the same location, is undiagnostic.  The generic name refers to "Kukufeld" ("Cuckoo's Field"), the name of Cuckfield in the eleventh century, and the specific name refers to Tilgate.  "Kukufeldia" is within Iguanodontia a member of the Styracosterna.
  Title: Portulaca grandiflora
  Passage: Portulaca grandiflora, (Urdu: گل دوپہری‎ )(Bengali: টাইম ফুল ) is a flowering plant in the family Portulacaceae, native to Argentina, southern Brazil, and Uruguay and often cultivated in gardens.  It has many common names, including rose moss, eleven o'clock, Mexican rose, moss rose, Vietnam Rose, sun rose, rock rose, and moss-rose purslane.
  Title: Galtonia
  Passage: Galtonia is a genus of plants in the family Asparagaceae, subfamily Scilloideae.  Native to Southern Africa, the genus is named after Sir Francis Galton.  According to some authorities it has been subsumed into "Ornithogalum" as a subgenus, while others prefer to keep it as a separate genus.
  Title: Sierritasuchus
  Passage: Sierritasuchus is an extinct genus of aetosaur in the subfamily Desmatosuchinae.  It is known from a small holotype skeleton from the Late Triassic Tecovas Formation of Texas.  This skeleton (known as UMMP V60817) was discovered in 1939 and was originally assigned to the genus "Desmatosuchus".  It was placed in its own genus in 2008 after having been in the collections of the University of Michigan Museum of Paleontology, with the type species being "S. macalpini".  The generic name refers to Sierrita de la Cruz Creek where the holotype was found, and the specific name refers to Archie MacAlpin, who discovered the skeleton.  Based on the histology of the scutes of the holotype, the individual was a subadult that was not fully grown.
  Title: Renphasma
  Passage: Renphasma is an extinct genus of stick insect which existed in what is now China during the early Cretaceous period.  It was named by André Nel and Emmanuel Delfosse in 2011, and the type species is "Renphasma sinica".  The generic name refers to Dr. Ren Dong, while the specific name refers to Sinica, the Latin name for China.
