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]
Krummholz Pinus albicaulis in Wenatchee National Forest Wind-sculpted krummholz trees, Ona Beach, Oregon. Krummholz (German: krumm, "crooked, bent, twisted" and Holz, "wood") — also called knieholz ("knee timber") — is a type of stunted, deformed vegetation encountered in the subarctic and subalpine tree line landscapes, shaped by continual exposure to fierce, freezing winds.
Later, in late summer, when the plants turn a greyish-white, plants growing in the wild are cut at the base and the thorns are removed. [102] Leaves, stems, roots, and particularly the undeveloped flowerheads can be eaten. [103] The base of the young leaves which is still under the surface is used by Bedouin and Arabs to make akkub soup.
This has resulted in non-flourishing trees, and the duration of the mist and cloud around the area seems to also be decreasing. Increasingly arid environments is predicted to cause a 45 percent reduction in the available habitat for D. cinnabari by 2080. [9] Additional threats include harvesting of its resin and use of the leaves to make rope.
Cinnabar is the common bright scarlet to brick-red form of mercury(II) sulfide. Cinnabar may also refer to: Cinnabar, the color of the mineral; Cinnabar, Queensland, a locality in the Gympie Region, Queensland, Australia; Cinnabar moth (Tyria jacobaeae), a brightly coloured arctiid moth; Cinnabar Theater, a theater in Petaluma, California, USA
Detail of an individual flower showing the white fruit that the genus is named after. Photo: Tony Rebelo. Leucospermum differs from genera such as Protea, Leucadendron, Mimetes, Diastella, Paranomus, Serruria, and Orothamnus by having the flower heads in the axils of the leaves (although often very near the tip of the branch), small and inconspicuous bracts subtending the head, brightly ...
Widely distributed in Eastern Northern America, it can be found from June to October, mostly on the ground in broadleaf and mixed broadleaf/conifer forests. It usually occurs scattered or in small groups. [5] It forms mycorrhizal associations with forest trees and shows preference for acidic soils. [6]
The Jin dynasty Daoist scholar Ge Hong's c. 320 CE Baopuzi (Master Who Embraces Simplicity) is the earliest surviving source of information about zhi excrescences.. Based upon no longer extant texts and illustrations, Chapter 11 (Xianyao 仙藥, Medicines of Immortality) outlines folklore and knowledge about zhi, and elucidates the wuzhi (五芝, Five Zhi) classification system.
