Genus containing one living species of flying lemur.

Members of a genus containing five species of gregarious, colony-forming rodents that live in extensive burrow systems in grasslands of plains, high plateaus, and montain valleys in North America, and have a call resembling a dog's bark.

Family containing around 110 genera and 5,500 species of plants, many growing in wetlands; they superficially resemble grasses or rushes by stems that are triangular in cross-sections and having leaves that are spirally arranged in three ranks (while grasses have alternate leaves forming two ranks).

Genus containing around 650 species of annual or perennial plants distributed throughout all continents, often in wetlands. The stems are circular or triangular in cross-section, usually leafless for most of their length with the slender grass-like leaves at the base of the plant.

Species of tall, robust, leafless aquatic plant growing to 5 m (16 feet) in height, forming a grass-like clump of green stems, triangular in cross section, that rise up from thick, woody rhizomes. Each stem is topped by a dense cluster of thin, bright green stems. It is edible to humans. It was cultivated in ancient Egypt, collected for its stalk or stem, the central pith of which was cut into thin strips, assembled in layers at right angles, pressed together, and dried to form a smooth, thin writing surface as early as the 3rd millennium BCE. Its use spread to the Greeks and then to the Roman Empire. Papyrus can darken and discolor with age. Other products were boats, sails, and cords. The species is now almost extinct in Egypt, but still of importance elsewhere in Africa as a fuel source. It is cultivated throughout the tropics; popular as an ornamental in Europe, Asia, and North America.

Family containing several species of small marine gastropods.

Cowrie shells (Cypraeidae) and egg shells (Ovulidae) that have highly polished and brilliantly colored shells and a mantle, which may cover the shell; if touched, members of group suddenly withdraw, the change in colour serving to confuse predators; common in shallow tropical oceans, some species in cooler waters.

Crystalline amino acid present in proteins and peptides. It has been explored as a non-toxic alternative to benzotriazole (BTA) for the conservation of archaeological objects with bronze disease.

A crystalline, sulfur-containing amino acid that is formed from two molecules of the amino acid cysteine. Cystine can be converted to cysteine by reduction. Cystine is particularly abundant in skeletal and connective tissues and in hair, horn, and wool.

Genus of flowering plant native to scrub and heathland in Europe, western Asia and North Africa, and is one of several genera in the tribe Genisteae which are commonly called brooms. These shrubs produce brightly colored, pea-like flowers that are often fragrant.

A deciduous broom of western Europe that is widely cultivated for its bright yellow or partly red flowers and that has become naturalized in North America. It has been used as textile dyestuff.

Da'e, literally "great forehead" (Kroll 2015, 73, 99) is usually used to refer to over-sized column-top tie beams often found in the timber architecture of Shanxi and Shaanxi constructed during the Yuan period (thirteenth-fourteenth centuries). As an architectural term, da’e is only recorded in the Yingzao fashi, but it is not clearly defined. Based on the context in which the term is used, it is possible that da’e is an alternate name for lan’e 闌額. This is because it is often used together with yan’e 簷額 and you’e 由額 where the term lan’e would normally appear. Still, nothing in the Yingzao fashi indicates that this so-called da’e is a larger size version of lan’e. In a seminal article, the twentieth-century architectural historian Zhang Yuhuan used this term to describe huge longitudinal beams found in Yuan timber architecture in Shanxi and Shaanxi. Since that time many modern scholars consider it to be the signature element of the so-called “da’e style” buildings of the Yuan dynasty. Da’e can be placed either under the eaves or inside the building, but must be parallel to the roof ridge as part of the zongjia 縱架. Some scholars believe that the Yuan dynasty da’e are equivalent to the yan’e in the Yingzao fashi, while others disagree.
