Asplenium listeri outside the Christmas Island National Park. Asplenium listeri Asplenium listeri, commonly known as the Christmas Island spleenwort, is a species of fern in the Aspleniaceae family. It is endemic to Christmas Island, an Australian territory in the north-eastern Indian Ocean. Its specific epithet honours British zoologist and plant collector Joseph Jackson Lister, who visited the island on in 1887 and was the first to collect a specimen. The spleenwort is a small, terrestrial, lithophytic fern with shortly creeping rhizomes, and with fronds up to 90 mm long held in a crown. Found only on Christmas Island, the fern is known
Chemical plant reactions or other chemical principles in a laboratory, commonly on a small scale in a "batch-type" experiment. Chemistry information obtained is then used by chemical engineers, along with expertise of their own, to convert to a chemical process and scale up the batch size or capacity. Commonly, a small chemical plant called a pilot plant is built to provide design and operating information before construction of a large plant. From data and operating experience obtained from the pilot plant, a scaled-up plant can be designed for higher or full capacity. After the fundamental aspects of a plant design are determined,
