Bangladesh is a rich land of biodiversity. About 6000 species of plants are gathered in such a small area of 147570 sq km.
I am trying to introduce the flora of Bangladesh in a pack from the naturalist view, not from the eye of plant-expert. For this, there will be some unwanted mistakes.
Needless to say, pics used in this site are all original and snapped by me. The information are gathered here from the personal notes, collected books and from different websites.
Maloncho or Alligator weed, Alternanthera philoxeroides
Maloncho or Alligator weed (Alternanthera philoxeroides, Amaranthaceae) is an aquatic or semi-aquatic perennial herb rooting at nodes. Stem is juicy, slender and hollow. So the plant can easily float on the water.
Other names: Heycha, Hechi-shak, Burma-shak, Bormi-shak.
Though the floating plant is found everywhere in Bangladesh, surprisingly it is native to Brazil. In the far past it has been introduced to the subcontinent and Southeast Asia.
Flowers are very small, white, on head inflorescence, petals 5. Peduncle is very long.
Leaves are green, slightly serrated, linear, elliptic-lanceolate, 3-8 cm long, opposite, acute at the end.
Fruit an utricle, ovoid-orbicular or obcordate. Seed is inverse, lenticular, single-seeded. Flowering occurs in the rainy season.
Propagation is caused by cutting or seeds. It grows in damp places, near pond and canal etc. Leaves are eaten as vegetables.
It is energizing, emollient and reputed to induce sleep. It can be found in shallow and stagnant water in beel-jheel, ditches and ponds.

It is planted in the country as a homestead tree too. Other Bangla names: Koyetbel, Chirpaki. Leaflet is small, 5-7, and 3-4 cm wide, opposite, cuneate or obovate. Leaves are scented.

Makal or Mahakal ( Trichosanthes tricuspidata , family: Cucurbitaceae) is a woody climber with tendril and branches, attaining a height of 10-12 m. The multiangular-branched plant climbs up very far by holding any tree in the forest. It is found in the hilly areas as well as plain forests and village thickets in Bangladesh. It is also found in Indian subcontinent, Australia and some countries of South and Southeast Asia. According to ancient Sanskrit scriptures the other names of the plant are Bishala, Mohendro-baruni. In the Himalayas it has been seen at an altitude of 5000 feet. There are many refferences to the fruit in Bangla and Sanskrit literature. Someone is very nice to look at but he/she is useless--writers usually jokingly give examples of this fruit. Its roots and attractive fruits are packed with medicinal properties. The size and shape of leaves may vary. These are multilobed or trilobed, alternate, rough in both sides, 5-12 cm long, petioled, cor
