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.

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.

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.
