Indonesian Institute of Sciences has announced two new species of orchids in the jungles of Borneo. Two new Dendrobium orchid was named flos-D Wanu Methuselah, PO'Byrne & JJ Wood and Dendrobium dianae Methuselah D PO'Byrne & JJ Wood.


Dendrobium orchids are included in the center section spesiasinya calcarifer suspects in the western part of Indonesia, namely Sumatra.

These two species scientifically described by Destario Methuselah (Botanical Garden Purwodadi-LIPI) with his two partners, Peter O'Byrne (orchid practitioners in Singapore) and JJWood (Researchers at the herbarium at Kew Botanical

Although supposedly based in Sumatra, according to researchers LIPI Destario Methuselah viva news in a statement Monday, September 27, 2010, research conducted simultaneously by researchers at the Herbarium of the Botanical Gardens Kew, the British researchers to observe areas of Sarawak and the Botanical Garden LIPI observation in Borneo, indicate that the island of Borneo is one of the main section Dendrobium speciation annually calcarifer always found a new species with high levels of endemism in article orchids.

The two new species were published in international journals Malesiana Orchid Journal at the end of September 2010 after going through the process of looking about two years. This publication will be an important reference point for researchers and the international community to the development of biology and taxonomy of the orchid stem anggrekan (Orchidaceae) in the region are Malesiana. The two new species of orchid was thought only a limited range have in the region of Borneo. Thus, this type classified as endemic species that need special attention for their conservation.

Typical Orchid 2

The first new species of Dendrobium orchid is Wanu-floss. This orchid has a flower with a width of 2.1 to 2.2 cm, bright yellow-green sepals petalnya wide open with the middle lobe of lip flowers are quite large, almost square and divided in shallow water on the edge. In an inflorescence can take 2-8 flowers that bloom at the same. In addition to the interest of a wide margin, a unique feature of this orchid on the callus hump-shaped "U" which ran on the lips of flowers. Flos-Wanu name means "flower Wanu" the name of Vincent Wanu, an orchid in Malang supporters who contributed to this research.

The second type is a Dendrobium orchid dianae who have an affinity with the morphology of Dendrobium muluense Sarawak, the difference as the two lip callus dianae D that runs parallel to the surface of the lobe and the longitudinal center of the flower lip. This orchid has a flower with a width of 1.6 to 1.8 cm, ranging in color from light yellow to dark green plain with bright red stripes on the sepals and petalnya. Perbungaannya connection between 4-12 and gather flowers, and a series of flower looks very solid. Another peculiarities, namely Dendrobium dianae color variations are very different. And the rest of this color variation is not important for sexy calcarifer.

According Destario, observation of the mind that there are at least five variations of color in this species, and between the color variations can be very extreme difference to be. Thus, horticulture, the diversity of colors in dianae D, it can be a great development potential sources of genes in the activities of selection and hybridization of orchids. The name of this orchid is devoted to orchid lovers and conservation of orchids in South Kalimantan (Banjarmasin) named Diana Rachmawaty.

"It is much to support our research in the field of taxonomy of orchids, a research area not much national attention, but still able to function optimally with the help many parts, including environmentalists and supporters of orchids , "said Destario.

In terms of culture, the Orchid is very adaptable to a height of 300-900 meters, with a light intensity of 50-70 percent. D-flos Wanu usually bloom in April, June and November. Although dianae D can bloom almost year round. The two orchids in this sexy as a wet roots calcarifer, and an open environment with lots of wind and ventilation. Dangerous parasite that is often contaminated mites.
