Orach

Orach, common name for a tall annual plant of the goosefoot family, native to Asia. Orach is also called garden orach and mountain spinach. It is cultivated in Europe and North America both as a foodstuff and as an ornamental. Orach grows to a height of 2 m (7 ft). Its furrowed stems bear soft, arrow-shaped leaves and small flowers in crowded clusters. The young shoots and leaves are eaten like spinach. 

Scientific classification: Orach is a member of the family Chenopodiaceae. It is classified as Atriplex hortensis. 

Endive

Endive, also escarole, common name for a plant (see Composite Flowers) having a curly, lettucelike head, with inner leaves that are used in salads. The inner leaves of the plant are sometimes blanched by enclosing the head of the endive in its outer leaves (which normally fall away) or by covering the entire plant with a special tube of paper. The long blanched shoot of chicory is called Belgian or French endive, or witloof.

Scientific classification: Endive belongs to the family Asteraceae 

Dandelion

Dandelion, common name for stemless perennial or biennial herbs of the composite flower family, especially the common dandelion. The species has long taproots, rosettes of deeply incised lanceolate leaves, and flat flower heads containing bright yellow florets on hollow, stemlike stalks. The root of the common dandelion contains a substance used as a laxative; the root is also roasted and ground as a substitute or adulterant for coffee. The leaves are used for salad greens and potherbs, and the flowers are sometimes used for making wine. It is occasionally cultivated, especially in Europe, but is found chiefly as a persistent weed in all temperate regions. The red-seeded dandelion is similar to the common species, but is smaller, with reddish seeds and darker down. A Russian species has some importance as a source of latex.

Scientific classification: 

Dandelions belong to the family Asteraceae (formerly Compositae). The common dandelion is classified as Taraxacum officinale, the red-seeded dandelion as Taraxacum erythrospermum, and the Russian species that is a source of latex as Taraxacum kok-saghyz.

Catsear

Catsear - Culinary Encyclopedia: "

Catsear, also known as Flatweed, Hawkweed, Cat’s ear and False dandelion, is an aromatic plant with green colored lobed leaves,which are used in various culinary preparations. The plant, botanically known as Hypochaeris radicata or Hypochoeris radicata, has bright yellow flowers similar to dandelion, hence, the name “false dandelion”. The long leaves of this herb and flowers are used in the same manner as dandelion; however, the leaves of this herb are not as bitter as that of dandelion.

Origin

Catsear is a low lying perennial herb that is found growing in most lawns. It is native to Europe; however, it was also introduced into America, Australia, New Zealand and Japan.

  

Culinary Uses

Catsear has many culinary uses, similar to that of dandelion - The leaves are usually blanched, steamed and cooked like any other leafy vegetable. This helps in removing the bitterness of the leaves, if any. Salads are made with the leaves, raw as well as boiled or steamed. The flowers can be battered and made into fritters.

A number of dishes are flavored with the petals of the flowers, which are also added to sautéed dishes.

In Greece and Crete, leaves of this plant are eaten raw, along with other similar herbs such as pachies and agrioradika. Alcoholic beverages such as wine are flavored with the petals of these flowers.

The roots of this herb are ground and roasted and used as a substitute for coffee.

 Medicinal Uses

Catsear leaves and catsear oil have many medicinal properties which include - The ability to treat liver infections and bile related problems. It is also used for treating kidney problems and acts as a diuretic.

It is a wonderful detoxifier and is also used for controlling cancer. As per studies, the herb helps in treating urinary tract infections in women and also helps in controlling inflammation. This herb can treat weak stomach, cirrhosis, gall stones, gall bladder problems, jaundice, rheumatism, dyspepsia, constipation and hypoglycemia.

  

Precautions

Catsear, like dandelion, is a rich source of vitamins and minerals. However, the pollen can cause allergic reactions in people who are sensitive to pollen. It can also cause allergies in some people, if eaten raw. The leaves and flowers can cause skin irritation in sensitive people; hence, care needs to be taken. People on potassium-sparing diuretics should avoid taking this herb, as the high content of potassium in the herb can lead to hyperkalemia.

Trivia

Catsear is believed to cause “stringhalt” in horses, in which the hind legs (one or both) go through a sudden flexion. This can cause the horse to trip and fall.

Coral

Coral, small, sedentary marine animal, related to the sea anemone but characterized by a skeleton of horny or calcareous material. The skeleton itself is also called coral. Although most corals form colonies by budding, there are some solitary corals; in both types the individual animals, called polyps, resemble the sea anemone in form.

Corals grow in warm and temperate climates and in the cold water found at greater depths, but they are most abundant in warm, shallow water; over 200 coral species are found in the Great Barrier Reef of Australia. In many shallow-water species the polyps contain unicellular plants, which may provide the high oxygen concentration required by such corals.

Stony Corals 

In the large group known as stony corals, or true corals (Madreporaria), each polyp secretes a cup-shaped skeleton, the theca, around itself. Some solitary corals of that group may reach a diameter of 10 in. (25 cm); in the colonial forms the individual polyps are usually under 1-8 in. (3 mm) long, but the colonies may be enormous. The body of each polyp is saclike, consisting of a wall of jellylike material surrounding a digestive cavity, with a single opening, the mouth, at the unattached end. The mouth is surrounded by tentacles used to capture small prey and is invaginated to form a pharynx leading into the body cavity. Thin sheets of tissue (mesentaries) extend radially from the wall to the pharynx, dividing the cavity. A second set of radial divisions is created by folds (septa) of the outer skeleton and body wall, which extend upward from the floor of the body cavity. Reproduction occurs both sexually and by budding. Sexual reproduction is by means of eggs and sperm, which are produced in the mesentaries and shed into the water. Fertilization results in a free-swimming larva, which attaches to a surface and secretes a skeleton, becoming (in colonial forms) the parent of a new colony. 

As new polyps are produced by budding they remain attached to each other by thin sheets of living tissue as well as by newly secreted skeletal material. The great variety in the form of various colonial corals, which may be treelike and branching, or rounded and compact, depends chiefly on the method of budding of the particular species. In the brain corals, for example, each theca merges with the one next to it on either side, forming long rows of polyps separated by deep channels. In some of the branching corals the polyps occupy small, discrete pits on the surface of the skeleton. As a colonial coral produces more polyps the lower members die and new layers are built up on the old skeleton, forming a large mass. In tropical and subtropical regions these massive corals, along with other plants and animals, may form a coral reef. Most of the reef-forming corals belong to the stony coral group. 

Soft Corals 

The soft corals (Alcyonaria) are a group of soft, often feathery forms, with skeletons composed of calcareous or horny particles imbedded in the body wall. Each polyp of a soft coral has eight tentacles. Among the well-known soft corals are the sea pen, sea pansy, whip coral, and organpipe coral. The precious red coral (Corallium) of the Mediterranean Sea, used for jewelry, also belongs to that group. The spicules of its skeleton are fused together. 

Classification: Stony and soft corals are classified in the phylum Cnidaria, class Anthozoa.

Common Species of Seaweed and Their Uses

The largest of the green algae, Ulva (sea lettuce), grows to a ribbon or sheet 3 ft (91 cm) long. It provides food for many sea creatures, and its broad surface releases a large amount of oxygen. Fucus, called rockweed or bladderwrack, is a tough, leathery brown alga (though it often looks olive-green) that clings to rocks and has flattened, branched fronds buoyed by air bladders at the tips.

Seaweeds, especially species of the red algae Porphyra (nori) and Chondrus, form an important part of the diet and are farmed for food in China and Japan; other species (often called laver) are eaten in the British Isles and Iceland. Commercial agar (vegetable gelatin) is obtained from species of red algae and is the most valuable seaweed product. Irish moss or carrageen (Chondrus crispus), a red alga, is one of the few seaweeds used commercially in the United States. After being bleached in the sun the fronds contain a high proportion of gelatin, which is used for cooking, textile sizing, making cosmetics, and other purposes. In Japan it is made into a shampoo to impart gloss to the hair.

The kelps generally include the many large brown seaweeds and are among the most familiar forms found on North American coasts. Some have fronds up to 200 ft (61 m) long, e.g., the Pacific coast Nereocystis and Macrocystis, found also off the Cape of Good Hope. Common Atlantic species include Laminaria and Agarum (devil's apron). The kelps are a source of salts of iodine and potassium and, to a lesser extent, other minerals. When the seaweed is burned, the soluble mineral compounds are removed from the ashes (also called kelp) by washing. They are used chiefly as chemical reagents and for dietary deficiencies in people and in livestock. Kelp is also a commercial source of potash, fertilizer, and medicines made from its vitamin and mineral content. Kelps are especially abundant in Japan, and various foods known as kombu are made from them.

The brown algae of the genus Sargassum are called gulfweed. They inhabit warm ocean regions and are commonly found floating in large patches in the Sargasso Sea and in the Gulf Stream. Gulfweed was observed by Columbus. Although it was formerly thought to cover the whole Sargasso Sea, making navigation impossible, it has since been found to occur only in drifts. Numerous berrylike air sacs keep the branching plant afloat. The thick masses of gulfweed provide the environment for a distinctive and specialized group of marine forms, many of which are not found elsewhere.

Seaweed

Seaweed, name commonly used for the multicellular marine algae. Simpler forms, consisting of one cell (e.g., the diatom) or of a few cells, are not generally called seaweeds; these tiny plants help to make up plankton. The more highly developed types of seaweed usually have a basal disk, called a holdfast, and a frond of varying length and shape, which often resembles a plant in having stemlike and leaflike parts.

Types of Seaweed

The simplest of the seaweeds are among the cyanobacteria, formerly called the blue-green algae, and green algae (division Chlorophyta), found nearest the shore in shallow waters and usually growing as threadlike filaments, irregular sheets, or branching fronds. The brown algae (division Phaeophyta), in which brown pigment masks the green of the chlorophyll, are the most numerous of the seaweeds of temperate and polar regions. They grow at depths of 50 to 75 ft (15–23 m). The red seaweeds (division Rhodophyta), many of them delicate and fernlike, are found at the greatest depths (up to 879 ft/268 m); their red pigment enables them to absorb the blue and violet light present at those depths.

Reproduction in Seaweeds

Seaweeds reproduce in a variety of ways. Lower types reproduce asexually. More advanced kinds produce motile zoospores that swim off, anchor themselves, and grow into new individuals, or they reproduce sexually by forming sex cells (gametes) that, after fusing, follow the same pattern. Sometimes pieces of a seaweed break off and form new plants; in a few species there is a cycle of asexual and sexual reproduction foreshadowing the alternation of generations characteristic of plants.
