Crataegus Columbiana
The name ''Crataegus columbiana'' is a source of considerable confusion. The species named by Thomas J. Howell is now considered to be the same as '' C. douglasii'', named earlier, and the earlier name should be used instead. However, some varieties of ''C. columbiana'' have also been named that are not related to ''C. douglasii''. ''C. columbiana'' has been used by some authors for '' Crataegus piperi'' Britton, which is now known as ''C. chrysocarpa'' var. ''piperi''.Phipps, J.B.; O’Kennon, R.J. (2004).

William Willard Ashe
William Willard Ashe (June 4, 1872 – March 18, 1932) was an American forester and botanist. He was known as a prolific collector of plant specimens and an early proponent of conservationism in the Southern United States. Early life Ashe was born in Raleigh, North Carolina to Samuel A'Court Ashe (1840 – 1938) and Hannah Emerson Willard. He was the oldest of nine children and grew up on the family's antebellum estate "Elmwood," where he spent much of his childhood exploring the nearby woods and fields looking for natural curiosities. He quickly took to collecting plant specimens, and by the time he entered college, Ashe required a two-story building to house his entire collection. As a young man, Ashe also spent time writing; and along with his brother Samuel, he produced a tract titled "The West End Sun" that included woodcuts made by W.W. Ashe himself. A copy of "The West End Sun" was placed in the cornerstone of the State Agricultural College Building in Raleigh. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
