? The Tang Dynasty poet Wang Gu [g incarnation] [1] described the ancient poem "Erythrina Flower", "The fog in the south is clear, and Erythrina is on the road of bloom Xin; The top of the forest is covered with rosy clouds, so don't feel energetic in summer. Zhu Jin was bullied by the British fire fighting, and the crane was scared and worried. I doubt that Di Qing will rush to clean up the spring breeze. " In the poem, Erythrina flowers are as bright as Xia Hong, dazzling and inspiring.
? I know two kinds of Erythrina at present. One is Erythrina cristata, alias Erythrina cristata, Erythrina brasiliensis and Ivory Red, which is named after the flag petal (outermost petal) of bloom looks like a cock's burning comb. The other is Erythrina, which is also bright red, slightly orange and full of wildness like a pheasant. Erythrina is a genus of Erythrina in Leguminosae, with more than 50 varieties.
? In mid-March, I happened to pass by the playground of Peking University and saw several strings of red buds of Celosia cristata. There are many cockscomb flowers everywhere in the park, but those who grow in the area with insufficient sunshine on the west side of tall buildings have never seen big buds.
? There are two Erythrina trees in the playground of Peking University, in the open space in front of the student dormitory downstairs. On weekdays, there is plenty of sunshine. These two Erythrina trees should be old. Thick chapped bark and gray trunk tell their age. It should be an adult cockscomb transplanted from other places. One tree is about 3 meters, and the other one is askew and grows eastward. The gardener propped it up with some old sticks to prevent it from falling down. Maybe.
? On March 26th, when I went to see Erythrina after the rain, I visited bloom for a while. The branches of each tree have already opened several strings. Erythrina blooms from March to July, and bloom's is amazing. Wang Zeng, the leader of Erythrina in Quanzhou at that time, wrote a poem. From a distance, I saw that the branches were all green and thick, and suddenly my umbrella was going to burn out. Flowers bloom first and then ripen every year. People who don't know what to do don't like red. "(Wang Quanzhou county magistrate).
? Kyle, an Italian traveler in the Song and Yuan Dynasties? Poirot in his "Kyle? In Polo's travels, Erythrina is also called Quanzhou. Quanzhou has been planting Erythrina since Jin Dynasty, which is called Erythrina Town Lane.
? The cockscomb after the rain is especially bright red and can be seen from a distance. The unopened bud is wrapped by sepals, long, like red ivory, pointing to the sky. Erythrina flowers are flower-shaped, with irregular horns and brown flower stalks. Flowers generally bloom gradually from bottom to top. Erythrina trees have long inflorescences, while Erythrina flowers with poor growth are relatively small, with inflorescences as short as 20.
? Abroad, Erythrina is the national flower of Argentina and Uruguay and the national tree of Los Angeles and Chile. The flower language of Erythrina is: prosperity, auspiciousness and wealth.
? The trunk of Celosia cristata is grayish brown with mottled bark. Bark and root can be used as medicine, which has antipyretic and diuretic effects. Pittosporum bark has the functions of expelling wind and removing dampness, relaxing tendons and activating collaterals. Erythrina bark is a poisonous plant, and its stem bark is poisonous.
? The Celosia cristata leaves are dark green, the poorly growing leaves are light green, the pinnate compound leaves are 3 leaflets, the petiole is oblong or oblong, the petiole is yellow, the base is green, and there are small hooks on the petiole, which are sharp. Forgive me for picking this heart-shaped leaf, but I was also punished accordingly. My finger was hooked by a sharp thorn and blood flowed out. Therefore, it is better for a gentleman to appreciate flowers than to do it.
Distribution: Erythrina cristata is native to the coral reefs of tropical and Pacific islands in America and Asia, and is now distributed in China, Guangdong, Guangxi, Fujian and Taiwan Province provinces, especially Quanzhou, Fujian.
