John Torrey was an American botanist, chemist, and physician. Throughout much of his career, Torrey was a teacher of chemistry, often at multiple universities, while at the same time pursuing botanical work. Dr. Torrey's botanical career focused on the flora of North America. His most renowned works include studies of the New York flora, the Mexican Boundary, the Pacific railroad surveys, as well as the uncompleted Flora of North America.
Asa Gray is considered the most important American botanist of the 19th century. His Darwiniana was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator.
Pinus echinata, the shortleaf pine, is a species of pine native to the eastern United States from southernmost New York, south to northern Florida, west to eastern Oklahoma, and southwest to eastern Texas. Shortleaf pine has the largest range of the southern US yellow pines, but reaches its ecological maxima around western Arkansas in the Ouachita Mountains. The tree is variable in form, sometimes straight, sometimes crooked, with an irregular crown. This tree reaches heights of 20–30 metres (65–100 ft) with a trunk diameter of 0.5–0.9 metres.
The Chenopodioideae are a subfamily of the flowering plant family Amaranthaceae in the APG III system, which is largely based on molecular phylogeny, but were included - together with other subfamilies - in family Chenopodiaceae in the Cronquist system. Food species comprise Spinach, Good King Henry, several Chenopodium species, Orache, and Epazote.
Torreya taxifolia, commonly known as the stinking-cedar or Florida torreya, but also sometimes as gopher wood or Florida nutmeg, is an endangered tree of the yew family, Taxaceae, found in the Southeastern United States, at the state border region of northern Florida and southwestern Georgia.
Cucurbita moschata is a species originating in either Central America or northern South America. It includes cultivars known as squash or pumpkin. C. moschata cultivars are generally more tolerant of hot, humid weather than cultivars of C. maxima or C. pepo. They also generally display a greater resistance to disease and insects, especially to the squash vine borer. Commercially made pumpkin pie mix is most often made from varieties of C. moschata. The ancestral species of the genus Cucurbita were present in the Americas before the arrival of humans. Evolutionarily speaking the genus is relatively recent in origin as no species within the genus is genetically isolated from all the other species. C. moschata acts as the genetic bridge within the genus and is closest to the genus' progenitor.
Baptisia is a genus in the legume family, Fabaceae. They are flowering herbaceous perennial plants with pea-like flowers, followed by pods, which are sometimes inflated. They are native to woodland and grassland in eastern and southern North America. The species most commonly found in cultivation is B. australis.
Aletris, the colicroot, colicweed, crow corn, or unicorn root, is a genus of flowering plants in the Nartheciaceae family, native to North America and to eastern and southeastern Asia, especially China. It was used as a component in Lydia Pinkham's original Vegetable Compound.
Iris purdyi is a species of iris known by the common name Purdy's iris, named after Carl Purdy. It is found in the redwood forests of California and into southern Oregon, and hence is also known as the redwood iris. The plant flowers from April to June.
Quercus minima, the dwarf live oak or minimal oak, is a North American species of shrubs in the beech family. It is native to the southeastern United States.
Sabal etonia, commonly known as the scrub palmetto is a species of palm. It is native only to peninsular Florida in the United States, where it is found in Florida sand pine scrub communities.
Tradescantia bracteata, the longbract spiderwort, or prairie spiderwort, is a species of Tradescantia. It is native to the northern and central Great Plains and Mississippi Valley regions of the United States, from Arkansas and Oklahoma north to Minnesota and Montana, with a few isolated populations farther east. It is grown for its purple flowers. It blooms from May to July in the US.
Elizabeth Gertrude Britton was an American botanist, bryologist, and educator. She and her husband, Nathaniel Lord Britton played a significant role in the fundraising and creation of the New York Botanical Garden. She was a co-founder of the predecessor to the American Bryological and Lichenological Society. She was an activist for protection of wildflowers, inspiring local chapter activities and the passage of legislation. Elizabeth Britton made major contributions to the literature of mosses, publishing 170 papers in that field.
Quercus geminata, commonly called sand live oak, is an evergreen oak tree native to the coastal regions of the subtropical southeastern United States, along the Atlantic Coast from southern Florida northward to southeastern Virginia and along the Gulf Coast westward to southern Mississippi, on seacoast dunes and on white sands in evergreen oak scrubs.
Agalinis skinneriana is a species of flowering plant in the family Orobanchaceae known by the common names Skinner's gerardia, Skinner's false foxglove and pale false foxglove. It is native to North America, where it occurs in Ontario south to Missouri and Louisiana.
Lyonia fruticosa, the poor-grub or coastal plain staggerbush, is a plant species native to the US states of Florida, southern Georgia and the extreme southern part of South Carolina. It grows in pine woodlands and shrub bogs at elevations less than 100 meters.
Aletris farinosa, called the unicorn root, true unicorn, crow-corn, white colic-root or white stargrass, is a plant species found across much of the eastern United States. It has also been reported from the southern part of Ontario, Canada. It is known from every state east of the Mississippi River except Vermont, as well as Texas, Oklahoma, Arkansas and Louisiana.
Aletris obovata is a plant species native to the southeastern United States.
Willard Webster Eggleston was an American botanist, employed by the United States Department of Agriculture Bureau of Plant Industry. He graduated from Dartmouth College in 1891 with a Bachelor of Science degree. In his work on the taxonomy of Crataegus, now known to be complicated by apomixis, polyploidy, and hybridization, he aimed to simplify, counteracting the proliferation of species names that other botanists had produced.
Rosa bracteata, commonly known as the Macartney rose, is a species of rose that is native to southern China and Taiwan, but is also present as an invasive in the US.
