در متن زیر ویژگی کدام نوع بلوط توصیف شده است؟بلوط ایرانی یا انگلیسی؟

This valley was the most pleasant we had yet seen it was one fursung in length, and a mile in breadth.

The leaves at some seasons of the year are entirely covered with the white deposit of an insect, the taste of which is bitter.
