Fraxinus quadrangulata is a species of flowering plant commonly known as the blue ash. The spelling of the word is broken down phonetically as frækˈsɪnəs kwɒdˌræŋɡjʊˈleɪtə. The first part of the word, frækˈsɪnəs, is pronounced with emphasis on the first syllable and sounds similar to "fraks-in-us". The second part, kwɒdˌræŋɡjʊˈleɪtə, is pronounced with a hard "k" sound followed by the emphasized syllable "ræŋɡjʊ", and ending with a soft "ə" sound at the end.
Fraxinus Quadrangulata, commonly known as the blue ash, is a species of deciduous tree belonging to the olive family (Oleaceae). It is native to the central and eastern regions of North America, including parts of the United States and Canada. The name "Fraxinus" is derived from the Latin word for "ash tree," while "Quadrangulata" refers to the characteristic square twigs found on this particular species.
Blue ash typically reaches heights of 30 to 60 feet (9 to 18 meters) and is known for its distinctive blue-gray bark, which tends to peel in small ridges. The compound leaves are opposite and pinnately compound, consisting of multiple leaflets with serrated margins. In the fall, the foliage turns yellowish, creating a vibrant display of colors.
One of the key distinguishing features of Fraxinus Quadrangulata is its resistance to emerald ash borer (Agrilus planipennis), a destructive invasive beetle that threatens many North American ash tree species. This resistance has made blue ash a desirable alternative for urban landscaping and reforestation projects.
In addition to its ecological importance, blue ash holds cultural significance as well. Historically, Native American tribes used various parts of the tree for medicinal purposes, including the treatment of snakebites and digestive ailments. The wood of Fraxinus Quadrangulata is also considered valuable for its strength and durability, commonly used in the manufacturing of furniture, flooring, and tool handles.
Despite its resilience to certain threats, Fraxinus Quadrangulata is classified as a vulnerable species due to habitat loss, logging, and other human activities. Conservation efforts are underway to protect and sustain populations of this remarkable ash tree for future generations.
The word "Fraxinus" derives from the Latin word "frāxinus", which means "ash tree". The term "Quadrangulata" is also derived from Latin, where "quadrangulāta" means "four-angled" or "angular". So when combined, "Fraxinus Quadrangulata" refers to a specific species of ash tree with four-angled branches.
