Mangroves (generally) are trees and shrubs that grow in saline coastal habitats in the tropics and subtropics. The word is used in at least three senses: (1) most broadly to refer to the habitat and entire plant assemblage or mangal, for which the terms mangrove swamp and mangrove forest are also used, (2) to refer to all trees and large shrubs in the mangal, and (3) narrowly to refer to the mangrove family of plants, the Rhizophoraceae, or even more specifically just to mangrove trees of the genus Rhizophora. Mangals are found in depositional coastal environments where fine sediments, often with high organic content, collect in areas protected from high energy wave action.

Sisal or sisal hemp is an agave Agave sisalana that yields a stiff fiber used in making rope. (The term may refer either to the plant or the fiber, depending on context.) It is not really a variety of hemp, but named so because hemp was for centuries a major source for fiber, so other fibers were sometimes named after it.

The Juncos, genus Junco, are small American sparrows. Their systematics are still very confusing after decades of research, with various authors accepting between three and twelve species. Despite their name appearing to derive from the Spanish term for the plant genus Juncus (rushes), these birds are seldom found among rush plants as these prefer wet ground while juncos rather like dry soil.

The name Chamomile or Camomile means "earth-apple", because of the applelike scent of the plant. It can refer to any of several distinct species in the sunflower family (Asteraceae): The Chamomile flower is most often consumed in the form of a bitter herb tea infusion. Taken internally, the infusion's effects include calming of the digestive tract, and easing of the spasms of irritable bowel syndrome, nocturnal cramps and period pains. It's a relaxant and sedative, so it is often taken against insomnia or anxiety. The infusion can be used externally to reduce minor skin irritation because of its mild antiseptic effect and it lightens the hair. Ingestion of the dried flowers has an emetic effect. See Matricaria recutita for more complete details.

Cloves (Syzygium aromaticum, syn. Eugenia aromaticum or Eugenia caryophyllata) are the aromatic dried flower buds of a tree in the family Myrtaceae. Cloves are native to Indonesia and used as a spice in cuisine all over the world. The name derives from French clou, a nail, as the buds vaguely resemble small irregular nails in shape. Cloves are harvested primarily in Indonesia, Madagascar, and Zanzibar, ; it is also grown in India called Lavang , Pakistan, and Sri Lanka. The clove tree is an evergreen which grows to a height ranging from 10-20 m, having large oval leaves and crimson flowers in numerous groups of terminal clusters. The flower buds are at first of a pale color and gradually become green, after which they develop into a bright red, when they are ready for collecting. Cloves are harvested when 1.5-2 cm long, and consist of a long calyx, terminating in four spreading sepals, and four unopened petals which form a small ball in the centre.

Coca is a plant in the family Erythroxylaceae, native to north-western South America. The plant plays a significant role in traditional Andean culture. Coca leaves contain cocaine alkaloids, a basis for the drug cocaine, which is a powerful stimulant. Coca should not be confused with the similarly named South American cocoa bean from which chocolate is made. The plant resembles a blackthorn bush, and grows to a height of 2–3 m (7–10 ft). The branches are straight, and the leaves, which have a green tint, are thin, opaque, oval, and taper at the extremities. A marked characteristic of the leaf is an areolated portion bounded by two longitudinal curved lines, one line on each side of the midrib, and more conspicuous on the under face of the leaf. The flowers are small, and disposed in little clusters on short stalks; the corolla is composed of five yellowish-white petals, the anthers are heart-shaped, and the pistil consists of three carpels united to form a three-chambered ovary. The flowers mature into red berries.
