Juglans cinerea is a species of tree that belongs to the family Juglandaceae. The spelling of the word 'Juglans cinerea' is based on the International Phonetic Alphabet system. The phonetic transcription for this word is ['dʒʌglænz sɪˈnɪrɪə]. The 'Juglans' part is pronounced with a 'j' sound followed by 'glans'. The 'cinerea' part is pronounced with a 's' sound followed by a long vowel 'i', followed by 'nere' pronounced like mullein.

Juglans cinerea, commonly known as the butternut or white walnut, is a tree species belonging to the Juglandaceae family. Native to the eastern parts of North America, it is primarily found in the northeast and central regions of the United States and southeastern Canada.
The butternut tree typically grows to a height of 20 to 30 meters and has a spread of about 10 to 15 meters. It possesses a somewhat open and irregular crown, composed of large compound leaves with 11 to 17 leaflets. The bark of mature trees is dark gray in color and develops deep furrows and ridges.
The fruit produced by Juglans cinerea is an oblong, thick-shelled nut, enclosed by a green, sticky husk. Upon maturity, the husk splits and falls away, revealing the light brown nut inside. Butternuts are typically harvested in the fall and are known for their distinctive buttery flavor.
This tree is valued not only for its ornamental appearance but also for its hardwood, which is highly durable and attractive. The wood is commonly used for furniture making, interior paneling, and flooring. The inner bark of the butternut tree has been traditionally used as a source for dye and herbal remedies.
However, besides its aesthetic and commercial value, Juglans cinerea faces numerous challenges, including a decline in population due to the spread of a disease called Butternut Canker, caused by the fungus Sirococcus clavigignenti-juglandacearum. Conservation efforts are being undertaken to protect and preserve this important tree species.
The word "Juglans cinerea" is a scientific name consisting of two parts, each with their own etymology.
1. Juglans: The genus name "Juglans" comes from the Latin word "jūglans", which means "walnut tree". The Latin term is believed to have originated from the combination of "Jovis" (genitive of Jupiter) and "glans" (nut), as walnuts were considered the "nuts of Jupiter" or "Jupiter's acorns". This name reflects the ancient Roman's belief that walnuts were associated with the god Jupiter.
2. Cinerea: The specific epithet "cinerea" comes from the Latin word "cinereus", meaning "ashen" or "grey". It refers to the grayish or silver color of the underside of the leaves.
