Cajuput (Melaleuca cajuputi)

Kayu putih or cajuput (Melaleuca cajuputi) is a tree in Myrtaceae as a medium to upper tree with thin skin and white, long slender green leaves and white flowers. This plant has important uses in agroforestry as a source of cajuput oil.

Cajuput is spread naturally in Indonesia and northern Australia. Indonesians traditionally use leaves to be distilled into essential oils of high economic value. This plant has a long biological cycle, grows fast and grows well in any soil with high salts or acids and is fire resistant.

M. cajupati was divided into three subspecies: Melaleuca cajuputi cajuputi growing in Maluku and Timor islands, Melaleuca cajuputi cumingiana growing in Sumatra, Java and Kalimantan, while Melaleuca cajuputi platyphylla growing in Papua, Aru Islands and Tanimbar Islands.

M. c. cajuputi generally produces cajuput oil with a 1.8-cineol content and high yield. While the other two sub-species have lower levels of cineol. Kayu putih oil from the Maluku Islands has a concentration of 1.8 sineol around 50% - 60% and high yield.

Volatile kayu putih oil where on a hot day people will smell it remotely. Oil is extracted through evaporation mainly from leaves and twigs as an industrial product for balur oil or a mixture of other medicinal oils or a mixture of perfume and other household products.

Generally these plants are found as pure stands and grow in the lowlands. The difference in location of growing and geographical places influences differences in flowering, fertilization and growth times, but the influence of the environment for growth, oil and reproduction characteristics still needs further research.

Paku tiang or pole fern or tiang fern ( Cyathea contaminans ) is a plant species in Cyatheaceae, has a height of up to 12 m, a single stem and the old part shows traces of leaves, the basal part is thickened by adventitious roots and grows mixed with other species. C. contaminans has stipe for 100 cm long, gloucous, purplish to the base, very thorny, when young has scales on all parts, up to 45x3 mm in size, pale brown, very thin and setiferous. The main rachis is pale, prickly, scaly as a stipe but then glabrescent. Pinnae has the largest size of 60 cm and the lowest decreases with stems up to 10 cm. Pinnules have a size of 150x30 mm or smaller with 1-2 pairs of basal segments more or not at all, the rest of the pine curved almost to the rib. Costules have a size of 4-5 mm. Common veins are 12 pairs. The lamina segment is hard, rough on the bottom and fibrous edges. Sori is exindusiate, near costule and pale paraphrase is no more than sporangia. The scales and hair on the pi...

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...

Sereng (Impatiens platypetala)

Sereng ( Impatiens platypetala ) is a plant species in Balsaminaceae, a perennial shrub, grows with erect stems up to 1 meter in height, brightly colored flowers and leaf shape depending on the subspecies, lives in damp or shady places in forests, waterways, roadsides and abandoned lands. I. platypetala has a tubular stem, reddish green or brownish green or whitish green depending on the subspecies and has clear boundaries like the segments where the petiole grows. Leaves have long and large stalks. Single leaf oval to lanceolate-ovate, 5-12 cm long, dark green, blunt base, pointed tip, serrated edge, a large bone and white in the center with several lateral veins. Flowers grow in the axillary of the leaves on the upper stem, have long stalks and stand. The crown is bright red or whitish red or bright orange with a dark color in the center. An eye grows in the middle with a white and green base. Kingdom: Plantae Phylum: Tracheophyta Subphylum: Angiospermae Class: Magnoliopsid...
