Crude Drug Identification
Botanical Information
Botanical Classification
A species of the genus *Cinnamomum* in the family *Juglandaceae*, commonly known as the Cinnamomum tree or round-fruited Cinnamomum.
Morphological Characteristics
1. Fragrant Tree
A deciduous small tree, 2–6 m tall. The bark is grayish-brown and irregularly fissured longitudinally; the branches are dark brown with small lenticels; they are covered with bud scales in winter, and the pith is solid.
(1) Leaves: Odd-pinnate compound leaves, alternate, 15–30 cm long,with 7–23 leaflets, sessile, ovate-lanceolate to long-elliptic-lanceolate, thin and leathery, 4–11 cm long, 1.5–3.5 cm wide, unequal in size, slightly sickle-shaped, with a nearly rounded base that is slightly asymmetrical on one side, a long acuminate apex, and doubly serrate margins.
(2) Flowers: Unisexual or bisexual; monoecious; bisexual and male inflorescences are borne at the tips of twigs or in leaf axils, arranged in corymbose clusters, with the central one typically being a bisexual inflorescence, the male inflorescences above, and the female inflorescences below; male inflorescences are arranged around the bisexual inflorescence, usually numbering 3–8;Male floral bracts are broadly ovate, with an acuminate apex, curving outward; they lack small bracts and perianth segments, and bear 6–8 stamens with filaments of varying lengths;The female inflorescences are globose-ovate or oblong; the female bracts are ovate-lanceolate, with a long, acuminate apex, rigid but not outwardly curved; they lack bracteoles and bear two perianth segments that are adnate to both sides of the ovary and enlarge together with it. Flowering occurs from May to June.
(3) Fruit: The fruit cluster is cone-like, ovoid-elliptic to oblong-cylindrical, 2.5–5 cm long and 2–3 cm in diameter; the nutlets are flattened, with narrow wings on both sides. The seeds are ovate, with a membranous seed coat. Fruiting period: July–October.
2. Round-fruited Fragrant Tree
The round-fruited fragrant tree differs from the fragrant tree in that: the petiole is nearly as long as or longer than the rachis; there are 3–5 (–7) leaflets; and the fruit cluster is globose, 1.2–2 cm in diameter. Flowering occurs in May, and fruiting occurs from June to July.
Distribution Area
1. Fragrant Tree: Distributed in East China, southern Shaanxi, Taiwan, Henan, Hubei, Hunan, Sichuan, Guizhou, Yunnan, and other areas. 2. Round-fruited Fragrant Tree: Distributed in Guangdong, Guangxi, Guizhou, and other areas.
