Question: Buckinghamia and Smyrnium are both what type of plant catagory?
Context: The abundances of plant species are often measured by plant cover, i.e. the relative area covered by different plant species in a small plot.  Plant cover is not biased by the size and distributions of individuals, and is an important and often measured characteristic of the composition of plant communities.  Plant cover data may be used to classify the studied plant community into a vegetation type, to test different ecological hypothesis on plant abundance, and in gradient studies, where the effects of different environmental gradients on the abundance of specific plant species are investigated. The William H. Zimmer Power Station, located near Moscow, Ohio, is a coal-fired power plant owned by Dynegy, Inc. It was originally intended to be a boiling water reactor type of nuclear power plant.  Although once estimated to be 97% complete, poor construction and quality assurance (QA) led to the plant being converted to coal-fired generation.  As of 2012, the plant generates 1460 gross MWe and 1300 net MWe.  Zimmer Power Station is the largest single-unit power facility in the United States.  During the construction of the plant, the Little Indian Creek was routed through the plant to protect fish populations.  The plant now has several unique environmental protection features to keep the creek at its natural state. Plant functional types (PFTs) is a system used by climatologists to classify plants according to their physical, phylogenetic and phenological characteristics as part of an overall effort to develop a vegetation model for use in land use studies and climate models. PFTs provide a finer level of modeling than biomes, which represent gross areas such as desert, savannah, deciduous forest.  In creating a PFT model, areas as small as 1 km are modeled by defining the predominant plant type for that area, interpreted from satellite data or other means.  For each plant functional type, a number of key parameters are defined, such as fecundity, competitiveness, resorption (rate at which plant decays and returns nutrients to the soil after death), etc.; the value of each parameter is determined or inferred from observable characteristics such as plant height, leaf area, etc. Buckinghamia celsissima, commonly known as the ivory curl, is a species of trees, constituting part of the plant family Proteaceae.  They grow naturally only (endemic) in the wet tropics rainforests areas of north eastern Queensland, Australia. Chilime Hydropower Plant is a run-of-the-river type plant situated in Chilime of Rasuwa district in Nepal, which is 133 km north of Kathmandu.  Its headworks are located near Chilime, whereas the underground power plant is located about 4.5 km to the southwest in Syafrubesi on the banks of the local Bhotekoshi river.  Water from a weir is diverted into a reservoir before it can be used at the power plant.  The difference in elevation between the reservoir and power station affords a gross hydraulic head (water drop) of 351.5 m .  The plant has an installed capacity of 22.1 MW.  The generated electricity is fed into the national grid via a 38 km 66 kV single circuit transmission line.  Most of the power house facilities are underground, with the switchyard the only feature that remains on the surface.The plant employs two horizontal axis Pelton turbines each of 11.28 MW. Smyrnium is a genus of flowering plants in the family Apiaceae, the umbellifers. Somatic embryogenesis is an artificial process in which a plant or embryo is derived from a single somatic cell or group of somatic cells.  Somatic embryos are formed from plant cells that are not normally involved in the development of embryos, i.e. ordinary plant tissue.  No endosperm or seed coat is formed around a somatic embryo.  Applications of this process include: clonal propagation of genetically uniform plant material; elimination of viruses; provision of source tissue for genetic transformation; generation of whole plants from single cells called protoplasts; development of synthetic seed technology.  Cells derived from competent source tissue are cultured to form an undifferentiated mass of cells called a callus.  Plant growth regulators in the tissue culture medium can be manipulated to induce callus formation and subsequently changed to induce embryos to form from the callus.  The ratio of different plant growth regulators required to induce callus or embryo formation varies with the type of plant.  Somatic embryos are mainly produced "in vitro" and for laboratory purposes, using either solid or liquid nutrient media which contain plant growth regulators (PGR’s).  The main PGRs used are auxins but can contain cytokinin in a smaller amount.  Shoots and roots are monopolar while somatic embryos are bipolar, allowing them to form a whole plant without culturing on multiple media types.  Somatic embryogenesis has served as a model to understand the physiological and biochemical events that occur during plant developmental processes as well as a component to biotechnological advancement.  The first documentation of somatic embryogenesis was by Steward et al. in 1958 and Reinert in 1959 with carrot cell suspension cultures. Leningrad Nuclear Power Plant (Russian: Ленинградская атомная электростанция; Ленинградская АЭС ( )) is a nuclear power plant located in the town of Sosnovy Bor in Russia's Leningrad Oblast, on the southern shore of the Gulf of Finland, some 70 km to the west of the city centre of Saint Petersburg.  It consists of four nuclear reactors of the RBMK-1000 type.  These reactors are similar to reactors No. 1 and 2 of the Chernobyl Nuclear Power Plant.  Two units of the VVER-1200 type are under construction at Power Plant II to replace the current RBMK reactors when they reach the end of their service lives. 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. Smyrnium olusatrum, common name Alexanders, is a cultivated flowering plant, belonging to the family Apiaceae (or Umbelliferae).  It is also known as alisanders, horse parsley, and smyrnium.  It was known to Theophrastus (9.1) and Pliny the Elder ("N.H. 19.48).
