Fruit micromorphology in the Umbelliferae of the Russian Far East

Botanical Garden, Lomonosov Moscow state University, Russia

Fruit micromorphology of all 65 native species of the Umbelliferae of the Rus sian Far Easrt was studied. We described cell arangement, cell form, fine relief of cell wall (cuticular foldings), epicuticular wax, stomata, crystals. Scanning electron microscope (SEM) also gave information on the inner structure of plant organs. We discuss the diversity of micromorphological characters and their taxonomic value. Some new diagnostic characters for the genera Kitagawia (areas with rugu late cuticle), Ligusticum and Magadania (large convex exocarp cells) were revealed.

Остроумова Т.А. Микроморфология плодов зонтичных российского Дальнего Востока. Изучена микроморфология плодов всех 65 видов зонтичных Российского Дальнего Востока. Мы описываем расположение клеток, их форму, скульптуру кутикулы, эпикутикулярный воск, устьица, кристаллы. С помощью сканирующего электронного микроскопа возможно также изучать внутреннюю структуру органов. Обсуждается разнообразие микроморфологических признаков и их значение для систематики. Для некоторых родов выявлены новые диагностические признаки: участки с морщинистой кутикулой у Kitagawia, крупные выпуклые клетки экзокарпа у Ligusticum и Magadania.

Keywords: Umbelliferae, taxonomy, identification, SEM, таксономия, определение, сканирующая электронная микроскопия
