Within the linguistic study of endangered languages, sociolinguists distinguish between different speaker types based on the type of competence they have acquired of the endangered language.
 Often in situations where a community is gradually shifting away from an endangered language to a majority language, not all speakers acquire full linguistic competence, but have varying degrees and types of competence depending on the kind of exposure to the minority language they experienced in their upbringing.
 Originally the relevance of speaker types in situations of language shift was noted by Nancy Dorian who coined the term semi-speaker to refer to those speakers of Sutherland Gaelic who were predominantly English-speaking and whose Gaelic competence was limited and showed considerable influence from English.
 Later studies added additional speaker types such as rememberers (who remember some words and phrases but have little or no grammatical competence and do not actively speak the language), passive speakers (who have nearly full comprehension competence but do not actively speak the language).
 In the context of language revitalization, neo-speakers who have learned the endangered language as a second language are sometimes distinguished.
Palaua is a genus of malvaceous plants native to the Andes.
 It shares with "Malope" and "Kitaibelia" the property of possessing capitate schizocarps, and was formerly classified with them in a subfamily Malopoideae or tribe Malopeae.
 It is now considered to be more closely related to "Sphaeralcea", and to other Andean mallows.
British NVC community MG13 (Agrostis stolonifera - Alopecurus geniculatus grassland) is one of the mesotrophic grassland communities in the British National Vegetation Classification system.
 It is one of three types of mesotrophic grassland classified as grass-dominated inundation communities.
The soma (pl.
 "somata" or "somas"), perikaryon (pl.
 "perikarya"), cyton, or "cell body" is the bulbous, non-process portion of a neuron or other brain cell type, containing the cell nucleus.
 The word "soma" comes from the Greek "σῶμα", meaning "body".
 Although it is often used to refer to neurons, it can also refer to other cell types as well, including astrocytes, oligodendrocytes, and microglia.
 There are many different specialized types of neurons, and their sizes vary from as small as about 5 micrometres to over 10 millimetre for some of the smallest and largest neurons of invertebrates, respectively.
Alopecurus, or foxtail grass, is a common and widespread genus of plants in the grass family.
 It is common across temperate and subtropical parts of Eurasia, northern Africa, and the Americas, as well as naturalized in Australia and on various islands.
Alopecurus aequalis is a common species of grass known as shortawn foxtail or orange foxtail.
 It is native to much of the temperate Northern Hemisphere from Eurasia to North America, where it can be found in many types of habitat.
There are currently two main types of power plants operating in Nigeria: (1) hydro-electric and (2) thermal or fossil fuel power plants.
 With a total installed capacity of 8457.6MW (81 percent of total) in early 2014, thermal power plants (gas-fired plants) dominates the Nigerian power supply mix.
 Electricity production from hydroelectric sources (% of total) in Nigeria was reported at 17.59 % in 2014, according to the World Bank collection of development indicators, compiled from officially recognized sources.
 There have been two main types of fossil fuel/thermal power plants in the country: (i) coal-fired and (ii) natural gas-fired.
Volcanic glass is the amorphous (uncrystallized) product of rapidly cooling magma.
 Like all types of glass, it is a state of matter intermediate between the close-packed, highly ordered array of a crystal and the highly disordered array of gas.
 Volcanic glass can refer to the interstitial, or matrix, material in an aphanitic (fine grained) volcanic rock or can refer to any of several types of vitreous igneous rocks. Most commonly, it refers to obsidian, a rhyolitic glass with high silica content.
A trellis (treillage) is an architectural structure, usually made from an open framework or lattice of interwoven or intersecting pieces of wood, bamboo or metal that is normally made to support and display climbing plants, especially shrubs.
 There are many types of trellis for different places and for different plants, from agricultural types, especially in viticulture, which are covered at vine training systems, to garden uses for climbers such as grapevines, clematis, ivy, and climbing roses or other support based growing plants.
 The rose trellis is especially common in Europe and other rose-growing areas, and many climbing rose varieties require a trellis to reach their potential as garden plants.
 Some plants will climb and wrap themselves round a trellis without much artificial help being needed while others need training by passing the growing shoots through the trellis and/or tying them to the framework.
Malope is a genus of three species in the mallow botanical family (Malvaceae).
 Of the three species, "Malope trifida" is often used as an ornamental plant.

Question: Do both Alopecurus and Malope refer to types of plants?
Answer: yes
