Quercus virgiliana

Quercus virgiliana, Ten. 1835, pubescence, acorn, leaf.  Pen and ink on 3.5"x2.5" Bristol board. I had a difficult time capturing the scales of this acorn; a lot of patterns and texture.

I chanced upon this almost perfectly ovoid acorn, Quercus virgiliana because I made a typographical error in searching for interesting facts about Quercus virginiana. What a magnificent discovery! This acorn is produced by the most beautiful and largest heritage oak trees in Southern Europe, East Corsica, Italy to the Black Sea. Quercus vigiliana or Roverella. There appears to be quite extensive documentation of heritage specimen throughout Italy. Check out these beautiful acorn images here and the majestic  1000 year old tree, the largest in Italy; a 250-300 year old specimen here and an estimated 400 year old tree here.

The leaf of the Quercus virgiliana is broadly oboval, 10-16 cm., flat with a rounded or cordate base. It has 5 to 7 pairs of often rounded lobes. It is woolly beneath. The petiole measures 1.5-2.5 cm.. The acorn is 3-4 cm in diameter, on a short peduncle, almost sessile; the cup has flat , lanceolate, reflexed scales. Ref: Oaks of the World

Why?

Some family trees may contain nuts.

I am not a botanist. I am a Sunday painter and pen and ink illustrator. I also love trees and leaves, and oaks and acorns. I studied speech pathology and nursing.I worked as a speech therapist and trauma nurse for many years. I am now a clinical analyst and I write clinical decision rule programs and modules. I also love trees and leaves, and oaks and acorns. Three years ago, I decided to embark on a project. I promised to illustrate a collection of the acorns of the world. This is the third year.  My love for trees was nurtured my by beloved mother. She was a conservationist without a personal agenda except a true love, respect and appreciation for nature especially plants and trees. She turned my childhood home into a dense grove and nursery of trees and plants. As metaphor goes, none exemplifies better the saying "sturdy oaks" as my parents did. Theirs was an honorable and exemplary life filled with virtue.

I dedicate this project to my beloved family and friends.

I am thankful to the many online botanical and academic sites that had supplemented the textbooks and live specimen resources I used complete these illustrations.
