What are the differences between the leaves of michelia figo and michelia alba
Among many aromatic plants, michelia figo and michelia alba are often confused. Although these two trees of the magnolia family have similar flower shapes, their leaves can be accurately identified. This article systematically sorts out the differential characteristics of the two from the perspective of plant morphology, helping horticulture enthusiasts master scientific identification methods.
Leaf Morphology Comparison
Differences in Shape and Size
The leaves of michelia figo are lanceolate-ovate, 10-20 cm in length and 4.5-9 cm in width, with a distinct sharp apex. The leaves of michelia alba are broadly inverted ovate, with a length-to-width ratio of 10-18 cm: 6-12 cm, and a blunt apex. When observing the curvature of the leaf surface, the former has shallow wave patterns on the edges, while the latter has more distinct undulating contours.
Differences in Venation and Texture
The veins of michelia figo are distributed in a pinnate pattern, with an angle of about 45 degrees between the main vein and secondary veins, and the leaves are leathery and thick. The reticular veins of michelia alba are more dense, with radial branches visible at the base of the main vein, and the leaf texture is relatively soft. When observed against the light, the former has more distinct sunken veins, while the latter has more transparent leaf flesh tissue.
Differences in Flowers and Blooming Period
Flower Color and Shape Characteristics
The flowers of michelia figo are ivory white with a hint of pale yellow, with 12-14 petals arranged in a spiral. The sepals and petals of michelia alba are distinctly differentiated, with 9 pure white petals and a淡 green base. The former can have a flower diameter of up to 15 cm, while the latter usually maintains around 10 cm.
Blooming Period and Fragrance Expression
The blooming period of michelia figo is concentrated from June to October, with a single flower lifespan of only 24-36 hours and a woody fragrance. Michelia alba starts flowering in April and continues to September, with flowers lasting more than 48 hours, and a sweet fragrance with a fruity undertone.
Differences in Growth Characteristics
Tree Shape and Canopy Features
Mature michelia figo can reach 20 meters in height, with a narrow umbrella-shaped canopy that extends vertically, and branching angles mostly between 50-60 degrees. Michelia alba is controlled within 17 meters in height, with a broad umbrella-shaped canopy that extends horizontally, and branching angles reaching 70-80 degrees. There are also differences in the bark textures of the two, with the former having shallow longitudinal cracks and the latter having deep gray scales peeling off.
Differences in Ecological Adaptability
Michelia figo is more drought-resistant and grows well in areas with annual precipitation of 800mm. Michelia alba requires higher air humidity and is suitable for planting in humid areas with annual precipitation of more than 1200mm. In terms of soil adaptability, the former can tolerate a pH of 6.0-7.5, while the latter is most suitable for a pH of 5.5-6.5.
Through systematic comparison, significant differences can be seen between the two plants in leaf morphology, flowering characteristics, and growth habits. Mastering these identification points can not only accurately identify species but also provide a scientific basis for garden configuration and maintenance management. It is recommended to combine field observation with microscopic testing to establish a multi-dimensional plant identification system.
