2. Tamilnadia uliginosa

Tamilnadia uliginosa is a small tree from Rubiaceae family. I have seen this tree since childhood. In my native place there is a medium size tree near the house. In fact this tree was like a childhood friend, as we used to play near it, pluck its flowers and fruits. This is a solitary tree. It stands alone, other phendra trees do not grow near it. In native language it is called 'Pendra'. Its various names still relate to this name : In hindi it is called Katul, Phendra, The fruit is cooked as a vegetable in some parts. But in my native place, nobody used anything from this tree, neither fruits nor flowers were of much use to the villagers. The Tree The Leaves The Flower The Fruit
