Are Buckinghamia and Stipa plants?
yes
Title: Kazakh semi-desert
Passage: 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.
Title: Buckinghamia
Passage: 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.
