Solitary rugosans are often referred to as horn corals because of a unique horn-shaped chamber with a wrinkled, or rugose, wall. Some solitary rugosans reached nearly a meter in length. However, some species of rugose corals could form large colonies. When radiating septa were present, they were usually in multiples of four.
Rugose corals were found from the Mississipian period (345 million yers ago)and have a skeleton made of calcite that is often fossilized. Like modern corals, rugose corals were invariably benthic, living on the sea floor or in a reef-framework. Although there is no direct proof it is inferred that these Palaeozoic corals were provided with stinging cells to capture prey. They also had tenacles to help them catch prey. Technically they are carnivores but prey-size was so small they are often referred to as microcarnivores. In marine geology and biology, benthos are the organisms and habitats of the sea floor; in freshwater biology they are the organisms and habitats of the bottoms of lakes, rivers, and creeks. ...
Rugosa roses are a class of nineteenth-century origin.
The result is a rose with exceptional cold tolerance and disease resistance, handsomely wrinkled foliage of the rugosa parents, but with a wider variety of flower form and color and a plant habit that ranges from compact shrubs to vigorous climbers.
Many rugosas are also tolerant of salt spray, which makes them good candidates for planting in areas where road salt spray is a problem.
