Mile-a-minute weed (Persicaria perfoliata)

Mile-a-minute weed (Persicaria perfoliata) is a species of plant in the Polygonaceae, perennial shrub, growing vines with thorny stems, triangular leaves, fruits in dense clusters, growing wild in forests, farmlands and roadsides.

P. perfoliata has a cylindrical, branched, reddish stem with rows of strong, downward-pointing spines. The leaves have long stalks and rows of spines. Green or reddish surface, pointed tip, three main veins with many small pinnate veins and lower surface has rows of spines.

Flower buds, flowers and fruit emerge from within the ocreas. Flowers are small, white and generally inconspicuous. The fruits grow in clusters, are round, segmented, green or yellow or red or blue, each segment containing a black or reddish-black seed.

Mile-a-minute weed prefers warm open areas on riverbanks, parks, open spaces, road shoulders, forest edges to very wet with poor soil structure. The fruit can stay afloat for 7-9 days and spread seeds long distances in river environments. Long vines often hang over waterways.

The tender leaves and shoots can be eaten raw or cooked as a salad green or sweet and can be eaten fresh. The stem is used as a fiber or material in making rope.

Liverwort (Marchantia)

Liverwort ( Marchantia ) is a genus of plants in the Marchantiaceae, growing vines and attached to the soil surface, soft, dark green, upright phallus like a cup, grows in colonies on slopes and vertical soil that is moist and shady. Marchantia has elongated strands, rounded ends, branched, flat margins and a black vein in the middle. The strands formed a circular formation, growing widely and forming new formations around it. Sexual reproduction involves sperm from antheridia in male plants to fertilize ova in archegonia in female plants. The zygote develops into a small sporophyte which remains attached to the larger gametophyte. The sporophyte produces spores which develop into free-living male and female gametophytes. Asexual reproduction via gemmae in the cup-like structures on the upper surface of the plant. Asexual reproduction can also occur when older plant parts die and new, surviving branches develop into separate plants. Kingdom: Plantae Phylum: Marchantiophyta Class: ...

Wild durian (Cullenia exarillata)

Wild durian ( Cullenia exarillata ) is a species of plant in the Malvaceae, a tall tree with smooth, greyish-white bark, peeling on older trees, a straight trunk, horizontal branches and often with a series of knob-like tubercles for flower and fruit attachment. C. exarillata has young branches and the underside of the leaves is covered with golden brown peltate or shield-like scales. The leaves are single, alternate, glabrous, glossy green on the upper side and covered with silvery or orange peltate scales on the underside. Hermaphroditic flowers are tubular and also covered with golden brown scales, 4-5 cm long and cream or reddish brown in color. Flowers have no petals, formed of tubular bracteoles and tubular calyxes, 5-lobed. Fruit is round, 10-13 cm in diameter, covered with thorns and clustered along the branches. Many seeds, reddish brown, 4-5 cm long and 2-3 cm wide. The seeds are enclosed by a fleshy, whitish aril. The fruit splits open when ripe and dries to release the s...
