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]
Leaves are pinnately lobed and +2.4 inches (61 mm) long and 1 inch (25 mm) wide, smaller towards the top of the plant. Leaves are sparsely covered with soft, smooth, fine hairs. Lobes typically sharp to rounded saw-toothed. [6] [7] The hollow [8] stems branch at the tops and from the base. [6] Stems and leaves can both host the Cineraria leaf ...
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.
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.
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 ...
Scadoxus cinnabarinus has at most a very short pseudostem, making the plant shorter than other species, with an overall height of up to 60 cm (24 in). The flowers are borne on a scape (leafless stem) which emerges from the centre of the leaves and is usually not much taller than them, with a height of 15–40 cm (6–16 in).
One way to control the spread of this fungus is pruning branches of trees that have cankers. N. cinnabarina is a saprophyte and mainly resides in and on dead tissue, but as the fungus progresses, it invades living tissue and causes further disease. Trimming the areas so that no dead tissue remains is important because this removes the areas ...
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.
