In biology, an indumentum (Latin, literally: "garment") is a covering of trichomes (fine "hairs") on a plant〔Davis, Peter Hadland and Heywood, Vernon Hilton (1963) ''Principles of angiosperm taxonomy'' Van Nostrandpage, Princeton, New Jersey, page 154, 〕 or of bristles (rarely scales) of an insect. In plants, indumentum types include: *pubescent *hirsute *pilose *villous *tomentose *stellate *scabrous *scurfy The indumentum on plants can have a wide variety of functions, including as anchorage in climbing plants (e.g., ''Galium aparine''), in transpiration control, the reflection of solar radiation, increasing water-repellency (e.g., in the aquatic fern ''Salvinia''), in protection against insect predation, and in the trapping of insects (''Drosera'', ''Nepenthes'', ''Stylosanthes''). The use of an indumentum on insects can also be pollen-related, as on bees, sensory like whiskers, or for varied other uses including adhesion and poison. ==See also== *Glossary of botanical terms 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「indumentum」の詳細全文を読む スポンサード リンク
