The papyprus is a frequent form in Egyptian ornament. Its straight, stiff triangular stem with four root-leaves wrapping its slightly swelling base, is imitated in the clustered shafts of many columnrs, and painted as a decoration on walls and on bell-capitals, often alternating with conventional lotuses. The stem bears a bunch of tiny flowers, forming with their stems a group of green filiments witht reddish tops, growing out of a calyz of four leaves or bracts. These supply the suggestion for many bell-shaped forms in Egyptian ornament, including the great campaniform capitals of the huge columns of the Karnak hypostyle hall.

"Date Palm is a genus of palms, the most important species of which is the common date palm, the palm tree of Scripture, a native of the N. half of Africa, the S. W. of Asia, and some parts of India, and of which the cultivation is no less wide, and still extending. Some parts of China produce large crops. The stem, which is straight and simple, reaches a height of 30 to 60 feet, and bears a head of 40 to 80 glaucous pinnated leaves, 8 to 10 feet long, and a number of branching spadices, each of which on the female tree bears 180 to 200 fruits. A bunch of dates weighs 20 or 25 pounds, so that an average year's crop may be reckoned at 300 to 600 pounds per tree, and the yield per acre at about 12 times that of corn. This is one of the most important and useful of all the palms. In Egypt, and generally in North Africa, Persia, and Arabia, dates form the principal food, and date palms the principal wealth of the people."&mdash;(Charles Leonard-Stuart, 1911)

"Viper's Bugloss is a genus of plants. The species are large herbaceous plants or shrubs, rough with tubercles and hairs. Their flowers are often very beautiful. the common viper's bugloss, a large annual plant, is a native of Great Britain and of most parts of Europe growing in dry places, not infrequently in cornfields. Its flowers are at first reddish, and afterward blue. It derives its name, viper's bugloss, from spots on its stem, which somehat resemble those of the viper, and the property of healing viper's bites was therefore ascribed to it. Other herbaceous species are found in North and South America, and other parts of the world. Shrubby species are found chiefly in the Canaries and South Africa."&mdash;(Charles Leonard-Stuart, 1911)

"Palm is a natural order of endogenous plants, the products of which are of extreme importance and utility to man. The size of the leaves varies, some being only a few inches in length, while in others they attain the enormous proportions of 35 feet in length by 5 or 6 feet in breadth. The flowers are small individually, but numerous, usually of a yellow tint, and in some species powerfully odorous. The fruit when ripe is berry-like, drupaceous, plum-like, or, as in the cocoanut, nut-like. The sugar palm is a native of the Moluccas, Cochin-China, and the Indian Archipelago, and is of immense value to the natives of these countries on account of its various products. It yields an abundant sweet sap, from which a chocolate-colored sugar is made. The sap fermented makes an intoxicating drink variously named by the inhabitants of the different countries. From the pith of the stem sago is obtained in great quantity, a single stem yielding as much as from 150 to 200 pounds."&mdash;(Charles Leonard-Stuart, 1911)
