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]
Near its base, the twiggy petiole bares a small, raised, oval gland. The leaves are confined to the outer shell of the crown, yet they are plentiful enough to make it moderately dense and green. The guanacaste is evergreen, or briefly deciduous for 1–2 months during the dry season. Most foliage is shed in December, at the start of the dry season.
The Wakasugiyama Cinnabar Mine (若杉山辰砂採掘遺跡, Wakasugiyama shinshasaikutsu iseki) is an archaeological site with the traces of a late Yayoi to early Kofun period cinnabar production site, located in the Suii neighborhood of the city of Anan, Tokushima on the island of Shikoku in Japan.
Its leaves are found only at the end of its youngest branches; its leaves are all shed every three or four years as new leaves simultaneously mature. Branching tends to occur when the growth of the terminal bud is stopped, through either flowering or traumatic events (e.g. herbivory).
Cinnabar moths are about 20 mm (0.79 in) long and have a wingspan of 32–42 mm (1.3–1.7 in). Cinnabar moths are day-flying insects with distinctive pinkish-red and black wings. There is little variation in patterning, although on rare occasions the red markings may be replaced with yellow, or the forewing is entirely red with a black border ...
They are herbaceous perennial plants with a large corm on or just below the ground surface. The leaves are large to very large, 20–150 cm (7.9–59.1 in) long, with a sagittate shape. The elephant's-ear plant gets its name from the leaves, which are shaped like a large ear or shield.
The hard, green leaves are set alternately along the branches, more or less directed upwards, oval or heart-shaped with an entire margin near the flowers and bluntly oblong and with up to six bony teeth at the tip lower down, 2–8 cm (0.79–3.15 in) long and 2–4½ cm (0.8–1.8 in) wide, softly hairy at first, becoming hairless.
This sympodial reed-stemmed Epidendrum displays a pseudomonopodial habit: an individual stem (to 1 m. tall), will grow continuously at the tip for some time bearing fleshy lanceolate green leaves, 2 cm. wide by 10 cm. long, before producing a terminal bloom spike, which usually equals or exceeds the length of the stem.
