(Sippl, Computer Dictionary, 4th ed)Botany: The study of the origin, structure, development, growth, function, genetics, and reproduction of plants.Lamiaceae: The mint plant family. They are characteristically aromatic, and many of them are cultivated for their oils. Most have square stems, opposite leaves, and two-lipped, open-mouthed, tubular corollas (united petals), with five-lobed, bell-like calyxes (united sepals).Porphyridium: A genus of RED ALGAE in the family Porphyridiaceae. A single stellate CHLOROPLAST is present in each cell which has no CELL WALL.Polygalacturonase: A cell wall-degrading enzyme found in microorganisms and higher plants. It catalyzes the random hydrolysis of 1,4-alpha-D-galactosiduronic linkages in pectate and other galacturonans. EC A yellow metallic element with the atomic symbol Au, atomic number 79, and atomic weight 197. It is used in jewelry, goldplating of other metals, as currency, and in dental restoration. Many of its clinical applications, such as ANTIRHEUMATIC AGENTS, are in the form of its salts.Seasons: Divisions of the year according to some regularly recurrent phenomena usually astronomical or climatic. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Public Facilities: An area of recreation or hygiene for use by the public.Musa: A plant genus of the family Musaceae, order Zingiberales, subclass Zingiberidae, class Liliopsida.Nurseries: Facilities which provide care for infants.Postal Service: The functions and activities carried out by the U.S. Postal Service, foreign postal services, and private postal services such as Federal Express.Schools, Nursery: Schools for children usually under five years of age.Crows: Common name for the largest birds in the order PASSERIFORMES, family Corvidae. These omnivorous black birds comprise most of the species in the genus Corvus, along with ravens and jackdaws (which are often also referred to as crows).Rosa: A plant genus in the family ROSACEAE and order Rosales.
