False nettle (Boehmeria cylindrica)

False nettle (Boehmeria cylindrica)

False nettle (Boehmeria cylindrica) is a species of plant in the Urticaceae family, a herb or small shrub, up to 160 cm tall, usually monoecious but rarely dioecious. The leaves are paired or alternate, and the inflorescence is a spikelet with a cluster of small bracts at the tip.

B. cylindrica generally grows to a height of 50-100 cm. Spine-like hairs form in the leaf axils. The leaves are oval and up to 10 cm long and 4 cm wide.



The flowers are green or greenish-white and emerge from the upper leaf axils. Male and female flowers usually grow on separate plants. Male flowers are more numerous among the spikes in clusters. Female flowers are less evenly distributed along the spikes.

The small, oval seeds are covered with small, hook-like hairs. Ripe seeds are dark brown. The inflorescence resembles a spike and is up to 3 cm long.

This species can be found in moist to mesic deciduous forest habitats, growing abundantly along streambanks, floodplains, and lowlands. B. cylindrica is wind-pollinated, so the flowers do not attract many insects.

Cempaki (Termitomyces microcarpus)

Cempaki ( Termitomyces microcarpus ) is a species of fungus in the Lyophyllaceae family. It grows wild in tropical Asian forests near termite nests. It is rarely reported in urban areas. It is edible and known for its deliciousness, high nutritional value, and difficulty in cultivating. In Indonesia, it is used as an alternative food ingredient. T. microcarpus is the smallest of the Termitomyces species, umbrella-shaped, plain white, measuring 5 cm tall and 2.5 cm wide. It grows in dense clusters on surfaces and forms a mutualistic relationship, requiring the metabolic activity of termites as a substrate for growth. This species is known for its deliciousness, rich in nutrients, and has potential bioactive properties, such as helping lower cholesterol and acting as a tonic. Currently, it is difficult to cultivate on a large scale, and people rely solely on wild harvests. This mushroom is highly favored for its savory, delicious flavor and soft, chewy texture. It is often stir-fried ...
