Copper beard orchid

From Wikipedia

By Vinuri Randhula Silva,

Calochilus campestris, commonly known as the copper beard orchid, is a species of orchid endemic to south-eastern Australia. It is grows in a wide range of habitats from heath to montane forest. It is found south from the Black down Tableland in Queensland, in coastal New South Wales and as far inland as Temora and is widespread in Victoria.

The Orchid family (Orchidaceae), with 25,000 to 30,000 different species that exist, are the largest family of plants in the entire world.Copper beard orchid has a single fleshy, channelled leaf and up to fifteen pale green and red flowers with a purple "beard".

It is a terrestrial, perennial, deciduous, herb with an underground copper beard orchid tuber and a single fleshy, channelled leaf 150–350 mm (6–10 in) long, 10–15 mm (0.4–0.6 in) wide and triangular in cross section. Between three and fifteen pale green flowers with reddish lines, 18–22 mm (0.7–0.9 in) long and 12–16 mm (0.5–0.6 in) wide are borne on a flowering stem 300–600 mm (10–20 in) tall. The dorsal sepal is erect, egg-shaped, 9–12 mm (0.4–0.5 in) long and 6–7 mm (0.24–0.28 in) wide. The lateral sepals are a similar length but narrower. The petals are lance-shaped to egg-shaped, 6–8 mm (0.2–0.3 in) long, 3–4 mm (0.1–0.2 in) wide and spread widely apart from each other. The labellum is egg-shaped and curved in side view, 14–16 mm (0.55–0.63 in) long and 5–6 mm (0.20–0.24 in) wide. The base of the labellum is fleshy and has two smooth, metallic blue plates and the middle part has bristly purple hairs. The tip has a short glandular "tail" 4–5 mm (0.16–0.20 in) long. The column has two sham "eyes" but without a ridge joining them. Flowering occurs from October to November but each flower only lasts between two and four days.

Why did Homo sapiens outlast all other human species?

From - Live Science By Mindy Weisberger Edited by - Amal Udawatta Reproductions of skulls from a Neanderthal (left), Homo sapiens (middle) and Australopithecus afarensis (right) (Image credit: WHPics, Paul Campbell, and Attie Gerber via Getty Images; collage by Marilyn Perkins) Modern humans ( Homo sapiens ) are the sole surviving representatives of the human family tree , but we're the last sentence in an evolutionary story that began approximately 6 million years ago and spawned at least 18 species known collectively as hominins. There were at least nine Homo species — including H. sapiens — distributed around Africa, Europe and Asia by about 300,000 years ago, according to the Smithsonian's National Museum of Nat ural History in Washington, D.C. One by one, all except H. sapiens disappeared. Neanderthals and a Homo group known as the Denisovans lived alongside H. sapiens for thousands of years, and they even interbred, as evidenced by bits of their DN

Jared Leto climbs Empire State Building

The actor and musician has become the first person to legally scale the 102-story Empire State Building. Leto, 51, climbed the outside of the New York landmark in a bright orange jumpsuit and using a rope and harness. He took on the challenge to promote the forthcoming world tour for his band Thirty Seconds To Mars. Leto told NBC's Today show: "I was more excited than nervous to tell you the truth. But I have to be honest, it was very, very hard. It was a lot harder than I thought it would be. "Just the endurance that it took, the stamina that it took, and it was very sharp." The actor won an Oscar for his

Humans have been speaking for a lot longer than we originally thought

From - Independent Magazine By - David Keys Edited by - Amal Udawatta New research has pinpointed the likely time in prehistory when humans first began to speak. Analysis by British archaeologist Steven Mithen suggests that early humans first developed rudimentary language around 1.6 million years ago – somewhere in eastern or southern Africa. “Humanity’s development of the ability to speak was without doubt the key which made much of subsequent human physical and cultural evolution possible. That’s why dating the emergence of the earliest forms of language is so important,” said Dr Mithen, professor of early prehistory at the University of Reading. Until recently, most human evolution experts thought that humans only started speaking around 200,000 years ago. Professor Mithen’s new research, published this month, suggests that rudimentary human language is at least eight times older. His analysis is based on a detailed study of all the available archaeological
