Snake plant (Sansevieria trifasciata)

Lidah mertua or Mother-in-law's tongue or snake plant (Sansevieria trifasciata) is a plant species in Asparagaceace, easily known from thick leaves, grows around pseudo stems above ground level and contains a lot of water, resists drought due to evaporation water and transpiration rate can be suppressed.

S. trifasciata has long, thick and stiff leaves, tapered at the upper end, bones are parallel, each rosette has 2-6 strands with crossed position, 15-150 cm long, 4-9 cm wide, slippery and green with texture silver or yellow patches.

Fiber roots grow from the base of the stem, white and fat. Rhizoma as a storage place for photosynthesis and propagation. Rhizoma spreads underground and sometimes above the ground. The tip is a meristem network that always grows elongated.

Flowers grow upright from the base of the stem, house two, pistils and pollen are not in the bud and emit a fragrance especially at night. Female flowers have pistils, while male flowers have pollen.

The fruit is produced from fertilizing pollen on the pistil's head. Seeds have an important role in breeding and single-beeping like other monocotyledonous plants. The outer part is a thick skin as a protective layer, on the inside of the skin is a plant embryo.

Snake plant is popular for indoor and outdoor ornamental plants, treating diabetes and hemorrhoids, inhibiting the growth of cancer cells, anti-poison snakes and insects, textile raw materials and has the ability to clean 107 types of pollutants in the air.

Sansevieria sp. able to absorb pollutants because it has the active ingredient pregnane glycoside which functions to reduce pollutants to organic acids, sugars and amino acids so that the pollutant elements are no longer harmful to humans. One leaf absorbs 0.938 mg formaldehyde in one hour.

Guinea grass (Panicum maximum)

Guinea grass or buffalo grass or green panic ( Panicum maximum ) is a plant species in Poaceae, annual grasses, growing upright to form clumps, strong, cultivated in all tropical and subtropical regions for very high value as fodder. P. maximum reproduces in very large pols, fibrous roots penetrate into the soil, upright stems, green, 1-1.5 m tall and have smooth cavities for diameters up to 2.5 mm. Propagation is done vegetatively and generatively. Ribbon-shaped leaves with a pointed tip, very many, built in lines, green, 40-105 cm long, 10-30 mm wide, erect, branched, a white linear bone, often covered with a layer of white wax, rough surface by hair short, dense and spread. The flower grows at the end of a long and upright stalk, open with the main axis length to more than 25 cm and the length of the bunches down to 20 cm. Grains have a size of 3x4 mm and oval. Seeds have a length of 2.25-2.50 mm and each 1 kg contains 1.2 - 1.5 million seeds. Guinea grass has two varieties. P...

Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...
