The Downy Oak or Pubescent Oak (Quercus pubescens) is an oak in the white oak section of the genus, Quercus sect. Carl Ludwig Willdenow ( 22 August 1765 - 10 July 1812) was a German Botanist, Pharmacist, and plant taxonomist The term oak can be used as part of the common name of any of about 400 species of Trees and Shrubs in the Genus Quercus (from Latin Quercus. It is native to southern Europe and southwest Asia, from northern Spain (Pyrenees) east to the Crimea and the Caucasus. Spain () or the Kingdom of Spain (Reino de España is a country located mostly in southwestern Europe on the Iberian Peninsula. The Pyrenees (Pirineos French: Pyrénées; Catalan: Pirineus; Occitan: Pirenèus; Aragonese: Perinés Crimea (kraɪˈmiːə or the Autonomous Republic of Crimea (Крим Автономна Республіка Крим Avtonomna Respublika Krym; Крым The Caucasus ( also referred to as North Caucasus) is a geopolitical region located between Europe Asia & Middle East It is also found in France and parts of central Europe.
It is a medium-sized deciduous tree growing up to 20 m. Botany Autumn leaf color. See --> In Botany and Horticulture, deciduous Plants, including A tree is a perennial Woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or Forest-grown trees grow tall, while open-growing trees develop a very broad and irregular crown. They are long-lived, to several hundred years, and eventually grow into very stout trees with trunks up to 2 m in diameter. Open-grown trees frequently develop several trunks. The bark very rough, light grey and divided into small flakes. Large trees develop very thick whitish bark cracked into deep furrows, similar to the Penduculate oak but lighter in colour.
The twigs are light purple or whitish, tomentose. The buds are small (3-6 mm) and blunt, light brown. The leaves are leathery usually 4-10 cm long (rarely to 13 cm) and 3-6 cm wide, usually widest beyond the middle. In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. The leaves group at the ends of twigs. The upper leaf surface is dark green and rough, the lower light green. Both leaf surfaces are covered with minute pubescence which is sometimes lost in older leaves by late summer. The young expanding leaves are whitish or pinkish with very soft tomentum. The leaf shape is very variable, divided into 3-7 pairs of deep or shallow lobes, which are usually divided into a few sublobes. The lobes are usually blunt, rarely sharp. The apex is usually wide and round. The base of the leaf is heart shaped, widely rounded or sometimes pointed. The petioles are 4-15 mm (rarely to 22 mm) long, stout and pubescent. The leaves are persistent late into the autumn, remaining green up to early winter. They eventually turn russet or brown and fall off.
The acorns are light brown to yellow, 8-20 mm long, usually thin and pointed. The acorn is the nut of the Oak tree (genera Quercus, Lithocarpus and Cyclobalanopsis, in the The acorn cups are light grey to almost white, with pointed, overlapping scales, covered with tomentum. The acorn stalks are thick and pubescent, up to 2 cm long. The acorns usually occur in groups of 2-5 on the same stalk.
Three subspecies are accepted by Flora Europaea:
- Quercus pubescens subsp. In Zoology, as in other branches of Biology, subspecies is the Taxonomic rank immediately subordinate to a Species. pubescens – central and southern Europe.
- Quercus pubescens subsp. anatolica O. Schwarz – southwest Asia, southeast Europe.
- Quercus pubescens subsp. palensis (Palassou) O. Schwarz – northern Spain, Pyrenees.
Downy Oaks typically grow in dry, lime-rich soils. Soil, often typeset as SOiL, is a four piece rock band from Chicago Illinois United States founded by Shaun Glass Tom Schofield Tim King and Adam Zadel It is a submediterranean species, growing from the coastline to deep in the continent. Its optimum is in the submediterranean region, characterized by hot dry summers and cold winters with little rain fall. In western and central Europe, Downy Oak is confined to areas with submediteranean microclimate (gorges, sandplains, steppe slopes) or to coastlines of former lakes.
