Африка гүлі – Spathodea campanulata түлігі

Genus of trees

Spathodea is a genus in the plant family Bignoniaceae. The single species it contains, Spathodea campanulata, is commonly known as the African tulip tree. The tree grows between tall and is native to tropical dry forests of Africa. It has been nominated as among 100 of the "World's Worst" invaders. This tree is planted extensively as an ornamental tree throughout the tropics and is much appreciated for its very showy reddish orange or crimson (rarely yellow), campanulate flowers. The generic name comes from the Ancient Greek words σπαθη (spathe) and οιδα (oida), referring to the spathe like calyx. It was identified by Europeans in 1787 on the Gold Coast of Africa.

The flower bud is ampule shaped and contains water. People sometimes play with these buds because of their ability to squirt water. The sap sometimes stains yellow on fingers and clothes. The open flowers are cup shaped and hold rain and dew, making them attractive to many species of birds.

The African tulip tree flower produces large flamboyant reddish orange flowers that have approximately five petals and are 8 15 cm long. The flowers are bisexual and zygomorphic. These are displayed in a terminal corymb like raceme inflorescence. Its pedicel is approximately 6 cm long. This flower also has a yellow margin and throat. The pistil can be found at center of four stamens that is inserted on the corolla tube. This flower has a slender ovary that is superior and is two celled. The seeds of this tree are flat, thin, and broadly winged.

In Neotropical gardens and parks, their nectar is popular with many hummingbirds, such as the black throated mango (Anthracothorax nigricollis), the black jacobin (Florisuga fusca), or the gilded hummingbird (Hylocharis chrysura). The wood of the tree is soft and is used for nesting by many hole building birds such as barbets. Unfortunately the flowers have a natural defence killing bees, and it is thought various other species who harvest its pollen.

In Uganda, two lepidopteran species, two termite species, and one bark beetle attack S. campanulata. In Puerto Rico nine insect species in the orders Hemiptera, Hymenoptera, Lepidoptera, and Thysanoptera have been reported as feeding on various parts of S. campanulata. The species is quite susceptible to butt and heart rot; wood of the tree rots quickly when in contact with the ground.

Its wood is too weak for construction use but ideal enough for boxes and toothpicks. Fijian children sometimes use its flower buds as water pistols.
