備註: 芸香科的特徵的辨識:用有坑的小枝、腫起的葉柄、葉片(或小葉片)的形狀、葉片厚薄等來認它. 有實物當然要試多樣嘢啦.info from hkwildlife.net 芸香科 (~30種) 口訣:芸香木本複葉生, 黃柏花椒橘柚橙. 花被四五覆瓦列, 花葉果實腺點呈. 木本.葉,花,果常有透明油腺點. 葉常互生,多為複葉. 雄蕊8-10. 單身複葉,主要在citrus屬(檸檬, 西柚, 柚, 柑橘, 橙). 其它三椏苦(掌狀3出複葉), 飛龍掌血 (掌狀3出複葉), 九里香(複葉), , 花椒(複葉), 欓花椒(複葉), 兩面針. 山油柑(單身複葉) 三椏苦的花萼、花瓣和雄蕊均為4數, 密茱萸屬 Melicope, 透明油点甚多。萼片及花瓣各4片; FOC: Shrubs, trees, or sometimes herbs, sometimes scrambling or scandent, sometimes armed, with aromatic volatile oils[芳香揮發油] contained in glands[腺體] visible at surface of at least leaves, young branchlets, inflorescences, flower parts, fruit, or cotyledons in seed. Stipules absent [or stipular excrescences rarely present]. Leaves alternate, opposite [or whorled], simple (petiole neither apically swollen nor articulate with leaf blade), 1-foliolate (in individual specimens at least some 1-foliolate leaves with petiole apically swollen and/or articulate with leaf blade), or variously compound. Flowers bisexual or unisexual, usually 3-5-merous, actinomorphic or rarely zygomorphic, hypogynous [or rarely perigynous]. Perianth in 2 series, with clearly differentiated calyx and corolla or sometimes in 2 irregular series or 1 series, with ± undifferentiated tepals. Sepals distinct or connate to their full length. Petals distinct [or rarely coherent or connate for part of their length]. Stamens usually as many as or 2 × as many as petals or sometimes more numerous; filaments distinct or sometimes coherent or connate for at least part of their length; anthers introrse or sometimes latrorse, longitudinally dehiscent. Disk [rarely lacking] within androecium, nectariferous, flattened, annular, cup-shaped, pulvinate, or sometimes columnar, bell-shaped, conic, or hourglass-shaped. Gynoecium of 1-5 distinct 1-loculed carpels or 2 to many partially to completely connate carpels; placentation axile [very rarely becoming parietal]; ovules 1 to many per locule. Fruit of 2-5 follicles [drupes or samaras] or a single follicle, capsule, or berry [or samara]. Seeds with relatively large embryo; endosperm present and fleshy or lacking. Oil glands of Rutaceae, when viewed from the surface of plant parts they occupy, are usually pellucid. They also appear to be ± isodiametric and to have ± definite patterns of distribution. In blades of leaves, for example, where they are most commonly observed, they are usually ± evenly scattered throughout, or sometimes they are restricted to the margins. Rarely they are alleged to occur only along the secondary veins of the blades. | |
