[3] The four subgenera are: Hulthemia (formerly Simplicifoliae, meaning "with single leaves") containing one or two species from Southwest Asia, R. persica and R. berberifolia (syn. R. persica var. berberifolia) which are the only species without compound leaves or ...
Quartz is, therefore, classified structurally as a framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. [9] Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation ...
Rose bengal solid and solution in water. Rose bengal (4,5,6,7-tetrachloro-2',4',5',7'-tetraiodofluorescein) is a stain. Rose bengal belongs to the class of organic compounds called xanthenes. [1] Its sodium salt is commonly used in eye drops to stain damaged conjunctival and corneal cells and thereby identify damage to the eye.
Suntory "blue" rose Rosa 'Cardinal de Richelieu' rose, used for the first genetic engineering experiments. Scientists have yet to produce a truly blue-colored rose; however, after thirteen years of collaborative research by an Australian company, Florigene, and a Japanese company, Suntory, a rose containing the blue pigment delphinidin was created in 2002 by genetic engineering of a white rose ...

Kuai Shen [噲參] was the most filial son to his mother. Once a black crane was injured by a bow hunter and in its extremity, went to Kuai.
Llanite is a porphyritic rhyolite with distinctive phenocrysts of blue quartz (a rare quartz color) and perthitic feldspar (light grayish-orangeish). The brown, fine-grained groundmass consists of very small quartz, feldspar, and biotite mica crystals.
Crystals show pleochroism from red to blue to violet. Dumortierite quartz is blue colored quartz containing abundant dumortierite inclusions. Dumortierite was first described in 1881 for an occurrence in Chaponost , in the Rhône - Alps of France and named for the French paleontologist Eugène Dumortier (1803–1873). [ 5 ]
