area Koriesh [139]
– The tree has a large, dense crown of leaves
– It may contain a specific phytoncides
– Self-pruning. Saving water
– The speed of growth of the tree makes it a useful plantation.
11.2.5 Bombax ceiba, L.
– Has a straight, tall trunk
– Deciduous in winter
– Red flowers appear in the spring before the new foliage
– Produces a capsule which, when ripe, contains white fibers like cotton
– Grows to an average of 20–60 m
– Widely planted in parks and on roadsides there because of its beautiful red flowers
which bloom in March/April.
11.2.6 Chorisia speciosa
– Deciduous trees
– In younger trees, the trunk is green due to its high chlorophyll content, which
makes it capable of performing photosynthesis when leaves are absent; with age,
it turns to grey
– The leaves are composed of five to seven long leaflets.
