. The families of flowering plants. Plants; Phanerogams. FAMILIES Oi' FLOWERING tLANTS. 83 dry and winged (called a .?amara) and in other genera, either a drupe (stone-fruit) or nut. Family Moraceae. Mulberry Family. Contains about 55 genera and nearly 1000 species, natives largely of tropical regions. 600 species belong to the single genus Mcus, the fig, which is of immense economic importance, as it is the chief source of caoutchouc and furnishes us also with deli- cious fruits. Strictly speak- ing, the part which is eaten is not the fruit, but the pulpy receptacle, in which are em- bedded* the numerous small dry achenes commonly known as seeds. A similar condition exists in Moms, the mul- berry; the claims of , this tree to economic considera- tion lie chiefly in the fact that it is the best food for silkworms. The Moraceae are distinguished from the preceding family by the structure of their fruit, and by the presence of a milky sap. Among the genera of interest may be mentioned Artooarpus, the breadfruit, which is an important item in the dietary of the natives where it grows; Brosmmm, the "cow-tree" of Venezuela, the sap of which furnishes a pleasant drink; Eumulus,. the common hop; Brmissonetia, the paper mulberry, an ornamental tree which has become naturalized in the eastern United States; and Cannabis, the hemp. Family Urticaceae. Nettle Family. Contains about 40 genera and nearly 500 species, very widely distributed. The majority are herbs, many of them provided with painfully stinging hairs. The sap is watery, and not of milky consistency, while the fruit is an achene.. Fig. 68—The Hemp Plant, CannaUs saliva. Dodge, Rept. No. 9, U. S. Dept. ot Agrio..
