The Stinging Nettles include ten genera, of which the most impor- tant are Urtica, which includes our common species, and Laportea, represented by our Wood Nettle ; to the latter belongs the Tree Nettle, L. gigas, of Australia, which reaches a height of Irom fifteen to forty metres (50 to 130 ft.), and whose sting is so severe as to produce dan- gerous results. Fies. 393-7.—Illusteatiohs or Uktioa itkbns. 577. — Cohort IX. Daphnales. Mostly shrubs or trees, with mono- clinous flowers ; ovary superior, one-celled, with a single seed con- taining no endo- sperm. Order Protea- cese.—A family of about 1000 species, confined almost en- tirely to the South- ern Hemisphere, and occurring in greatest abundance in A us- tralia and South Africa. Many spe- cies, especially of the genus Bankda, are cultivated in conservatories, ble timber. Orevillea robusta, the Silk Oak of Australia, attains a height of twenty-four to thirty metres (80 to 100 ft.), with a diameter of two metres or more, and supplies valuable timber. Knightia exeelsa is a valuable New Zraland timber tree thirty metres (100 ft.) or more in height. Leucadendron argenteiim, the Silver Tree of the Cape of Good Hope, has silvery lanceolate leaves; its wood is much used for fuel. Protea grandiflora, the " Wageu-boom " of the same region, is used by wheelwrights in the manufacture of wagon wheels. Order Elseagnaceee.—A small order, of sixteen species, of trees or.
