Cinnabar is the more stable form, and is a structure akin to that of HgO: each Hg center has two short Hg−S bonds (each 2.36 Å), and four longer Hg···S contacts (with 3.10, 3.10, 3.30 and 3.30 Å separations). In addition, HgS is found in a black, non-cinnabar polymorph (metacinnabar) that has the zincblende structure. [5]
Upper leaves of Senecio vulgaris are sessile, lacking their own stem , alternating in direction along the length of the plant, two rounded lobes at the base of the stem and sub-clasping above. Leaves are pinnately lobed and +2.4 inches (61 mm) long and 1 inch (25 mm) wide, smaller towards the top of the plant.
The cinnabar moth (Tyria jacobaeae) is a brightly coloured arctiid moth found as a native species in Europe and western and central Asia then east across the Palearctic to Siberia to China. It has been introduced into New Zealand , Australia and North America to control ragwort , on which its larvae feed.
The dragon blood tree has an upturned, densely packed crown. This evergreen species is named after its dark red resin, which is known as "dragon's blood". Unlike most monocot plants, Dracaena displays secondary growth, D. cinnabari even has growth zones resembling tree rings found in dicot tree species.
A plant that loses all of its leaves only briefly before growing new ones, so that it is leafless for only a short time, e.g. approximately two weeks. bristle A straight, stiff hair (smooth or with minute teeth); the upper part of an awn (when the latter is bent and has a lower, stouter, and usually twisted part, called the column ).
Pycnoporus cinnabarinus, also known as the cinnabar polypore, is a saprophytic, white-rot decomposer. Its fruit body is a bright orange shelf fungus . It is common in many areas and is widely distributed throughout the world.
The plant is generally considered to be biennial but it has the tendency to exhibit perennial properties under certain cultural conditions (such as when subjected to repeated grazing or mowing). [7] The stems are erect, straight, have no or few hairs, and reach a height of 0.3–2.0 metres (1 ft 0 in – 6 ft 7 in).
In 1835, "Chinese vermilion" was described as a cinnabar so pure that it only had to be ground into powder to become a perfect vermilion. Historically, European vermilion often included adulterants including brick, orpiment , iron oxide , Persian red , iodine scarlet —and minium (red lead), an inexpensive and bright, but fugitive lead-oxide ...
