\"Capt<\/a>Press. Dry. Mount.<\/p>\n

That\u2019s the basic process for turning a plant into a research specimen that will last indefinitely, and it\u2019s stayed the same for hundreds of years for a good reason: It works.<\/p>\n

As proof, here\u2019s a member of the daisy family that botanists Joseph Banks and Daniel Solander clipped in January 1769 in Tierra del Fuego, at the southern tip of South America. They were part of the scientific team aboard the HMS Endeavour<\/em> on Captain James Cook\u2019s first voyage around the world. This 248-year-old specimen, still holding onto its leaves and retaining most of its color, is now part of the collection of 7.8 million preserved plants in NYBG\u2019s William and Lynda Steere Herbarium, the second largest in the world.
\n
\nEssential for a wide variety of plant research, ranging from climate change and conservation to evolution and biodiversity, these specimens all follow the same route from the wild to the climate-controlled confines of the Steere Herbarium. The scientists who collect them in the field flatten them in a wooden plant press and then dry them over a heat source. Back at the Herbarium, specially trained staff members mount them on archival paper, using a water-soluble glue and, if necessary, attaching larger pieces by sewing them to the paper. The specimens are arranged on the paper to make sure that all of the parts of the plant necessary to identify or study it are showing\u2014such as the tops and bottoms of leaves\u2014and then the sheet is labeled with extensive information about where and when the plant was collected.<\/p>\n
