Systematic Studies on Some Korean Woody Plants


Abstract
Floral morphology of Magnoliaceae and Illiciaceae in Korea is investigated. Magnoliaceae has long and elongate floral axis where numerous stamens and pistils are spirally arranged, whereas Illiciaceae has short floral axis and pistils are arranged in a single whorl on the axis. The stamens are basically similar in both families; winged and broad filament, prominant connective, long sporangium, and no clear limitation between fertile and sterile parts, which are primitive characters in stamen. The ovaries are the conduplicate type, in both, with decurrent stigma, stigmatic surface confined to stylar position, and no distinct style. Magnoliaceae has one locule and two ovules, whereas Illiciaceae has one locule and one ovule. The ovule is anatropous or hemianatropous, and has bitegmic integument and crassinucellate nucellus.
