• A family of herbs, shrubs, or trees (order Polygonales) chiefly of the north temperate zone having mostly entire leaves with stipules forming a sheath round the stem and flowers that are spicate and apetalous and including the buckwheats.

Use for: Gramineae, grasses

• grass family of monocotyledonous flowering plants, a division of the order Poales. The Poaceae are the world’s single most important source of food. They rank among the top five families of flowering plants in terms of the number of species, but they are clearly the most abundant and important family of the Earth’s flora. They grow on all continents, in desert to freshwater and marine habitats, and at all but the highest elevations. Plant communities dominated by grasses account for about 24 percent of the Earth’s vegetation.

• the pine family of conifers, consists of species of trees (rarely shrubs) native to northern temperate regions. Contain many species that are sources of timber, paper pulp, oils, and resins. Some are cultivated as ornamentals.

Use for: brown algae

• A class of algae, common in cold waters along continental coasts. Species colour varies from dark brown to olive green, depending upon the proportion of brown pigment (fucoxanthin) to green pigment (chlorophyll).
• Brown algae vary in form and size from small filamentous epiphytes (Ectocarpus) to complex giant kelps that range in size from 1 to more than 100 metres (3.3 to 330 feet; Laminaria, Macrocystis, Nerocystis). Other brown algae can be found attached to rocky coasts in temperate zones (Fucus, Ascophyllum) or floating freely (Sargassum). Freshwater species are rare. Brown algae multiply by asexual and sexual reproduction; both the motile zoospores and gametes have two unequal flagella. Some seaweed species have gas-filled bladders (pneumatocysts), which keep photosynthetic parts of the algal thallus floating on or near the surface of the water.

Use for: geranium

• a genus of southern African herbs of the Acanthaceae family with showy flowers of usually red, pink, or white distinguished by a spurred calyx and irregular corolla

• a large genus of hemiparasitic herbs found in temperate or alpine regions that have pinnate or pinnatifid leaves and variously colored bilabiate flowers in terminal spikes.

Use for: passerine

• the largest order of birds and the dominant avian group on Earth today.
• The passeriform birds are true perching birds, with four toes, three directed forward and one backward. Considered the most highly evolved of all birds, passerines have undergone an explosive evolutionary radiation in relatively recent geological time and now occur in abundance on all continents except Antarctica and on most oceanic islands.
• Their rapid evolution and adaptation to virtually all terrestrial environments resulted in a large number of species, some 5,700, compared with only about 4,069 species of all other birds.
