Kaempferia rotunda is a plant species in the ginger family.
 It is native to China (Guangdong, Guangxi, Hainan, Taiwan, Yunnan), India, Nepal, Assam, Bangladesh, Indochina, and widely cultivated elsewhere.
 It is reportedly naturalized in Java, Malaysia and Costa Rica.
Wulfenia is a plant genus in the family Plantaginaceae.
 Named after Franz Xaver von Wulfen (1728–1805), it was first described in 1781 by Nikolaus Joseph von Jacquin.
Kaempferia galanga, commonly known as kencur, aromatic ginger, sand ginger, cutcherry, or resurrection lily, is a monocotyledonous plant in the ginger family, and one of four plants called galangal.
 It is found primarily in open areas in Indonesia, southern China, Taiwan, Cambodia, and India, but is also widely cultivated throughout Southeast Asia.
Kaempferia is a genus of plants in the ginger family.
 It is native to China, India, and Southeast Asia (Thailand, Malaysia, Indonesia, Philippines, etc.).
A concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines various ingredients to form concrete.
 Some of these inputs include water, air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement.
 There are two main types of concrete plants: "Dry mix" plants and "Wet mix" plants, and also plants that contain both a transit mix side and a central mix side while utilizing common material storage points.
 A concrete plant can have a variety of parts and accessories, including: mixers (either "tilt drum" or "horizontal" or in some cases both), cement batchers, aggregate batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, cement silos, batch plant controls, and dust collectors.
The Sawyer and Keeler-Wolf classification system is an evolving system of classification of vegetation types, plant communities, or floristic characterization.
 It was first developed in 1995 by John O. Sawyer and Todd Keeler-Wolf for the California Native Plant Society, in the mission to classify all vegetation in California.
 Particular attention was paid to recognizing rare types that were "lumped" into general categories in previous systems, such as the Munz and Keck classification system, Chetham and Haller classification system, and Holland classification system.
 It uses constantly updated quantitative measurements of both species diversity and cover to define its types.
 It intended to be evolving and to continue to be refined.
A plant community (sometimes "phytocoenosis" or "phytocenosis") is a collection or association of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types.
 The components of each plant community are influenced by soil type, topography, climate and human disturbance.
 In many cases there are several soil types within a given phytocoenosis.
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.
Kaempferia parviflora (Thai black ginger, Thai ginseng or krachai dum) is an herbaceous plant in the family Zingiberaceae, native to Thailand.
 Among the Mong people, it is believed to improve physical work capacity, but clinical study has failed to support this belief.
Wulfenia carinthiaca, commonly named wulfenia, is a plant of the plantain family.
 It is endemic to the Gartnerkofel mountain of the Carnic Alps at the Austro-Italian border.

Question: Are Kaempferia and Wulfenia both types of plant?
Answer: yes
