Galium Verum01
''Galium'' is a large genus of annual and perennial herbaceous plants in the family Rubiaceae, occurring in the temperate zones of both the Northern and Southern Hemispheres. Some species are informally known as bedstraw. Over 600 species of ''Galium'' are described, with estimates of 629 to 650 as of 2013. The field madder, '' Sherardia arvensis'', is a close relative and may be confused with a tiny bedstraw. ''Asperula ''Asperula'', commonly known as woodruff, is a genus of flowering plants in the family Rubiaceae. It contains 91 species and has a wide distribution area from Europe, northern Africa, temperate and subtropical Asia to Australasia Australasi ...'' is also a closely related genus; some species of ''Galium'' (such as woodruff, '' G. odoratum'') are occasionally placed therein. Genetic variability The phenotypic plasticity and genetic variability of this species allows it to be constantly shifting to best fit its environment, adjusting lifecycles, seed ge ...

Gallium
Gallium is a chemical element; it has Chemical symbol, symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, elemental gallium is a soft, silvery metal at standard temperature and pressure. In its liquid state, it becomes silvery white. If enough force is applied, solid gallium may fracture conchoidal fracture, conchoidally. Since its discovery in 1875, gallium has widely been used to make alloys with low melting points. It is also used in semiconductors, as a dopant in semiconductor substrates. The melting point of gallium, , is used as a temperature reference point. Gallium alloys are used in thermometers as a non-toxic and environmentally friendly alternative to Mercury (element), mercury, and can withstand higher temperatures than mercury. A melting point of , well below the freezing point of water, is claimed for the alloy galinstan (62–95% gallium, 5–22% indium, and 0–16% tin by weight), but that may be t ...
