Context paragraphs:
Samuel Bonsall Parish: Samuel Bonsall Parish (1838 - 1928) was a California botanist and curator of the herbarium at Stanford University.  A number of plants were named in his honor, including "Acanthoschyphus parishii", "Allium parishii", "Atriplex parishii", "Boechera parishii", "Chaenactis parishii", "Cheilanthes parishii", "Delphinium parishii" ssp.  "pallidum", "Delphinium parishii" ssp.  "parishii", "Ericameria parishii", "Erigeron parishii", "Eriogonum parishii", "Eschscholzia parishii", "Euphorbia parishii", "Galium parishii", "Grusonia parishii", "Heuchera parishii", "Lycium parishii", "Malacothamnus parishii", "Mimulus parishii", "Orobanche parishii" ssp.  "brachyloba", "Orobanche parishii" ssp.  "parishii", "Perideridia parishii", "Phacelia parishii", "Plagiobothrys parishii", "Puccinellia parishii", "Silene parishii", "Solanum parishii", "Stipa parishii", "Symphoricarpos parishii", "Tauschia parishii", "Trichostema parishii", "Viguiera parishii", and others.

Stipa: Stipa is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass.  They are placed in the subfamily Pooideae and the tribe Stipeae.

Achnatherum: Achnatherum is a genus of plants which includes several species of needlegrass.  Several needlegrass species have been switched between "Achnatherum" and genus "Stipa"; taxonomy between the two closely related genera is still uncertain.

Kazakh semi-desert: The Kazakh semi-desert is an ecoregion in the deserts and xeric shrublands biome, located in Kazakhstan.  The climate is semi-arid and continental, with a total annual precipitation of 160 mm , and mean temperatures in January averaging -15 °C and in July 23 °C .  It is a transitional area between the steppes and the deserts of Central Asia and supports flora found in both biomes, predominantly grasses, particularly "Stipa" species, and shrubs such as "Artemisia" species.  A number of mammals and birds are found in this ecoregion but the habitat is threatened by overgrazing and fragmentation from human encroachment.  However, a recent reduction in livestock numbers in Kazakhstan is allowing the native plants a greater opportunity to regenerate.

Buckinghamia: Buckinghamia is a genus of only two known species of trees, belonging to the plant family Proteaceae.  They grow naturally only (endemic) in the rainforests of the wet tropics region of north eastern Queensland, Australia.  The ivory curl flower, "B. celsissima", is the well known, popular and widely cultivated species in gardens and parks, in eastern and southern mainland Australia, and additionally as street trees north from about Brisbane.  The second species, "B. ferruginiflora", was only recently described in 1988.
