Dark spots on flower petals are common across many angiosperm plant families and occur on flowers such as some lilies, orchids, and daisies. Much research has been done on the physiological and behavioral mechanisms for how these spots attract pollinators. But have you ever wondered what these spots are composed of, how they develop, or how they only appear on some but not all of the ray florets? http://www.physorg.com/news180376920.html Biology Fri, 18 Dec 2009 16:43:21 EST news180376920 (PhysOrg.com) -- Charles Darwin and many other scientists have long been puzzled by the evolution of orchids, the largest and most diverse family of flowering plants on Earth. Now genetic sequencing is giving scientists insights into how these plants could evolve so quickly. http://www.physorg.com/news177838192.html Biology Thu, 19 Nov 2009 07:32:40 EST news177838192 Three Thai orchids have been found to rely on a wide range of fungi to help them take carbon out of the soil instead of producing their own organic carbon. A detailed study of the relationship, published in the open access journal BMC Biology, also features stunning pictures of the plants. http://www.physorg.com/news169411384.html Biology Thu, 13 Aug 2009 20:20:01 EST news169411384 Borneo (Kalimantan) is the third largest island in the world. It is rich with a variety of indigenous orchid species that grow in the forests. Borneo's rain forests are also home to some extremely rare species of orchids, all highly valued for their exotic aromas and aesthetic beauty. It has been estimated that 2500 to 3000 orchid species grow in the forests of Borneo. http://www.physorg.com/news135510875.html Space & Earth Thu, 17 Jul 2008 10:54:35 EST news135510875
