Question

Phyllodes are found in
(a)Acacia auriculiformis
(b)Parkinson aculeata
(c)Both (a) and (b)
(d)None of the above

Answer 1

Hint: One is a fast-growing tree that is native to Australia, Indonesia and can grow up to 30 meters tall while the other is a species of perennial flowering tree that can be a tiny shrub or a small tree that can grow up to 2-8 meters high with a maximum height of 10 meters

Complete answer:
Phyllodes are found in Acacia auriculiformis and Parkinson aculeata. Phyllodes are the modified leaves stems or the petioles which become flattened and widened. They reduce or vanish altogether and constitute a leaf-like appearance which is similar in function to the leaves. Acacia is evergreen trees with a trunk that is up to 12 meters long and 50 cm wide. The trunk is crooked with vertically fissured bark. It constitutes shallow and spreading roots with dense foliage opening and spreading crown. Parkinson constitutes 8cm long flowers that occurred in pairs and are green-yellow and sweet-scented. It constitutes hair fewer leaves and stems with alternate and pinnate leaves. It constitutes five sepals and five petals which are rhomboid ovate.

Additional information:
Acacia plant is raised as an ornamental plant that is used for fuelwood throughout southeast Asia and other countries. The wood of this plant is good for making paper, tools, and furniture which contains tannin that is useful in animal hide tanning. These words are used for fuel in India and the gum from the tree is sold commercially which is useful as gum Arabic. Parkinson is used as foliage which is browsed by livestock due to spines. It is used for medicinal purposes for fever and epilepsy through which the leaves are steamed and made into medicines. These trees can tolerate a high range of drought and attain a shorter stature.

So, the correct answer is 'Both (a) and (b)'.

Note: Acacia auriculiformis can grow in loamy sand soils and well-drained Sandy soils instead of watercourses and swamps in low open forest. They can grow up to 35 meters high and can range from brown to black with funicle encircling seed. Parkinson aculeata is also known as Jerusalem thorn which is mostly grown near rivers and manmade water points in the semi-arid regions having a wet and dry climate.
