What is a tuberous root?
In practice it is quite difficult to distinguish a tuber from a tuberous root.
Edible tuberous roots
As an example of plant producing edible tuberous roots we have the cassava
– Cassava (Manihot esculenta = Manihot utilissima) is a plant with tuberous roots that belongs to the Euphorbiaceae family, where some well-know herbs are included such as poinsettia (Euphorbia pulcherrima) and other shrubs such as Castor oil plant (Ricinus communis)
Cassava is a perennial shrub 1 to 3 meters high. Thin stems that show the scars of their previous leaves. They are located at the top of the stems. Being palmado-lobed, they have up to 9 lobes and somewhat reminiscent of those of castor oil plant.
The most striking of the plant is its huge number of tuberous roots in 5-10 per plant. These can be up to 1.2 meters long and up to 23 cm in diameter.
From these roots, rich in starch, flour is obtained which is the main ingredient in the production of many food and drinks.
Cassava is also known as manioc, mandioca, yuca, mogo or kamoteng kahoy. It is actually a cultivated plant that can not be found in the wild nowadays.
