Charles Sprague Sargent
Charles Sprague Sargent (April 24, 1841 – March 22, 1927) was an American botanist. He was appointed in 1872 as the first director of Harvard University's Arnold Arboretum in Boston, Massachusetts, and held the post until his death. He published several works of botany. The standard botanical author abbreviation Sarg. is applied to plants he identified. Early life Sargent was the second son of Henrietta (Gray) and Ignatius Sargent, a Boston merchant and banker who grew wealthy on railroad investments. He grew up on his father's 130-acre (53-ha) estate in Brookline, Massachusetts. He attended Harvard College, where he graduated in Biology in the class of 1862. Sargent enlisted in the Union Army later that year, saw service in Louisiana during the American Civil War, and was mustered out in 1865. He traveled in Europe and Asia for three years. Career Having returned to his family's Brookline estate, "Holmlea", Sargent took over its management as a horticulturist, influence ...

Crataegus Coccinea
''Crataegus coccinea'', the scarlet hawthorn, is a species of hawthorn around which there is considerable confusion because the name has been misapplied for a long time. It has been shown to be the same as ''C. pedicellata'', and under the rules of botanical nomenclature, the older name (''C. coccinea'') should be used. Taxonomic history In 1901, Charles Sprague Sargent chose a lectotype for ''Crataegus coccinea'' from among Linnaeus's specimens, but chose a specimen that resembles ''C. dodgei'' Ashe. Sargent's lectotype opinion was followed by other authors until he realized his error and corrected it in 1909. The name ''C. coccinea'' has also been misapplied to specimens of '' C. intricata'' Lange. For almost 100 years, particularly since 1910, this species was generally called ''Crataegus pedicellata'' Sarg. except by a few authors. Linnaeus's original description was inadequate to make a decision between various unrelated species, including ''C. nigra'', ''C. phaenopyrum'', ...

Crataegus Pennsylvanica
''Crataegus pennsylvanica'', known as the Pennsylvania thorn, is a species of hawthorn Hawthorn or Hawthorns may refer to: Plants * '' Crataegus'' (hawthorn), a large genus of shrubs and trees in the family Rosaceae * ''Rhaphiolepis'' (hawthorn), a genus of about 15 species of evergreen shrubs and small trees in the family Rosace ... native to Delaware, New York, North Carolina, Ontario, Ohio, and Pennsylvania, that grows to about 8 m in height.
