Quercus robur, commonly known as common oak, pedunculate oak, European oak or English oak, is a species of flowering plant in the beech and oak family, Fagaceae. It is native to most of Europe west of the Caucasus. The tree is widely cultivated in temperate regions and has escaped into the wild in scattered parts of China and North America.
The white oaks are species of trees in the genus Quercus section Quercus.
Quercus ilex, the evergreen oak, holly oak or holm oak, is a large evergreen oak native to the Mediterranean region. It takes its name from holm, an ancient name for holly. It is a member of the Cerris section of the genus, with acorns that mature in a single summer. Quercus rotundifolia was previously thought to be part of this species, but was later moved to its own.
Quercus petraea, commonly known as the sessile oak, Cornish oak, Irish Oak or durmast oak, is a species of oak tree native to most of Europe and into Anatolia and Iran. The sessile oak is the national tree of the Republic of Ireland, and an unofficial emblem in Wales and Cornwall.
Live oak or evergreen oak is any of a number of oaks in several different sections of the genus Quercus that share the characteristic of evergreen foliage. These oaks are not more closely related to each other than they are to other oaks.
Rosacea is a long-term skin condition that typically affects the face. It results in redness, pimples, swelling, and small and superficial dilated blood vessels. Often, the nose, cheeks, forehead, and chin are most involved. A red, enlarged nose may occur in severe disease, a condition known as rhinophyma.
Ocular rosacea is a manifestation of rosacea that affects the eyes and eyelids. Signs and symptoms generally consist of redness, irritation or burning of the eyes. Affected individuals may also feel that there is something, such as an eyelash, in the eye and frequently have redness of the nose and cheeks as well.
Scrub oak is a common name for several species of small, shrubby oaks. It may refer to:
Perioral dermatitis, also known as periorificial dermatitis, is a common type of skin rash. Symptoms include multiple small (1–2 mm) bumps and blisters sometimes with background redness and scale, localized to the skin around the mouth and nostrils. Less commonly the eyes and genitalia may be involved. It can be persistent or recurring and resembles particularly rosacea and to some extent acne and allergic dermatitis. The term "dermatitis" is a misnomer because this is not an eczematous process.
Rhinophyma is a condition causing development of a large, bulbous nose associated with granulomatous infiltration, commonly due to untreated rosacea. The condition is most common in older white males.
The pink-headed imperial pigeon is a species of bird in the family Columbidae found in the Lesser Sunda Islands of Indonesia. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, and subtropical or tropical moist shrubland. It is threatened by habitat loss.
Steroid-induced rosacea is an iatrogenic condition from the use of either systemic steroid or topical steroids. It is nearly identical to steroid induced acne from the standpoint of etiology.
Mycteroperca rosacea, the leopard grouper or golden grouper, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the Eastern Central Pacific that occasionally makes its way into the aquarium trade.
Gnathophyma involves swelling of the chin. It is a type of lesion associated with rosacea, a common chronic inflammatory skin disorder of the sebaceous glands characterized by redness, swelling, and acne-like pustules.
A pimple is a kind of comedo that results from excess sebum and dead skin cells getting trapped in the pores of the skin. In its aggravated state, it may evolve into a pustule or papules. Pimples can be treated by acne medications, antibiotics, and anti-inflammatories prescribed by a physician, or various over the counter remedies purchased at a pharmacy.
Quercus × rosacea, is a naturally occurring hybrid species of oak native to Europe. They are the offspring of sessile oak, Quercus petraea, and common oak, Quercus robur, found where their ranges overlap. As hybrids, they are morphologically variable, but in general their traits appear intermediate to those of the parents. A thin section of a Q. × rosacea specimen was used by artist-in-residence Tania Kovats to create a monumental work called TREE for the ceiling of the Mezzanine of the Natural History Museum, London in celebration of the bicentennial of Charles Darwin's birth.
