Wax flower (Hoya lacunosa)

Wax flower (Hoya lacunosa) is a plant species in Apocynaceae, epiphytic, gummy, round stem, segmented, up to 3 meters long, slightly woody, grows twisted or hanging or attached to tree bark with short roots and very firmly attached.

H. lacunosa has leaves with three different shapes, including heart-shaped, green, 2-2.5 cm long, 3 mm thick, 1-2 cm wide, a wavy surface between the leaf bones, flat edges, pointed and protruding tips. The leaves contain a white sap or liquid.

Dlium Wax flower (Hoya lacunosa)


A single root, minimalistic and not branched, arises from the stem and does not gather at a single point, is small and short, is brown and is tightly attached to the bark of the host tree and there are usually colonies of black ants.

Compound flowers arranged in bunches. The petals, crown and corona are five each. The corona is an additional crown. The reproductive organs consist of the pistil and stamens which are arranged in the gynostemium. The extended stigma is rectangular and in the center of the corona.

The stamens compact and form the pollinia structure. Each bud has five pairs of pollinia. The pollinia structure consists of a corpusculum and translator apparatus. Flowers have a fragrance and contain a lot of honey which ants, butterflies, bees and birds are very fond of.

Each bunch blossoms for a period of time, but it rarely produces fruit. Most flowers are in November. The flower formation stage to anthesis is 4-5 weeks and fruit development from pollination to breaking is 4-6 weeks.



Wax flower can grow and produce flowers at a temperature of 27C, humidity 70-84%, light intensity 9.28-13.28 MJ/m2/day and rainfall 55-550 mm. Flowering lasts for most of the year, alternated by two months.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

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 ...
