Cyathea geluensis is a species of tree fern native to central and eastern New Guinea as well as the Louisiade Archipelago, where it grows in mossy forest.
 In New Guinea itself, plants grow at an altitude of 1000–2000 m, however they are present at lower elevations of 700–900 m on associated islands.
 The trunk of this tree fern is erect and may be 5 m tall or more.
 Fronds are bi- or tripinnate and 1-2.5 m long.
 They are usually about ten live fronds present in the crown at once.
 The stipe may be warty and/or have short spines as well as many scattered scales towards the base.
 These scales are pale to dark and have dull, fragile edges.
 Sori occur near the fertile pinnule midvein and are protected by pale, thin indusia.
 "C. geluensis" is a variable taxon and further study is needed to determine whether it does not in fact represent a species complex.
Carpobrotus, commonly known as pigface, ice plant, sour fig, and Hottentot fig, is a genus of ground-creeping plants with succulent leaves and large daisy-like flowers.
 The name refers to the edible fruits.
 It comes from the Ancient Greek "karpos " "fruit" and "brotos " "edible".
Cyathea chinensis is a species of tree fern native to Yunnan in China, Sikkim in India, as well as Nepal, Myanmar, Laos and Vietnam.
 Plants grow in forest and montane forest at an altitude of 900-1800 m.
 The trunk is erect and 1-2 m tall.
 Fronds are bipinnate and 1-2 m long.
 The stipe is either long and warty or has short spines towards the base as well as scattered glossy dark brown scales with fragile edges.
 Sori occur near the midvein of fertile pinnules and are covered by thin indusia.
Oxalis stricta, called the common yellow woodsorrel (or simply yellow woodsorrel), common yellow oxalis, upright yellow-sorrel, lemon clover, or more ambiguously and informally "sourgrass" or "pickle plant", is a herbaceous plant native to North America, parts of Eurasia (including India ), and has a rare introduction in Britain.
 It tends to grow in woodlands, meadows, and in disturbed areas as both a perennial and annual.
 Erect when young, this plant later becomes decumbent as it lies down, and branches regularly.
 It is not to be confused with similar plants which are also often referred to as "yellow woodsorrel".
Cress (Lepidium sativum), sometimes referred to as garden cress to distinguish it from similar plants also referred to as cress (from old Germanic cresso which means sharp, spicy), is a rather fast-growing, edible herb.
Chervil ( ; Anthriscus cerefolium), sometimes called garden chervil to distinguish it from similar plants also called chervil, or French parsley, is a delicate annual herb related to parsley.
 It is commonly used to season mild-flavoured dishes and is a constituent of the French herb mixture fines herbes.
Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales.
Pilgrim Nuclear Power Station (PNPS) is the only nuclear power plant operating in Massachusetts.
 It is located in the Manomet section of Plymouth on Cape Cod Bay, south of the tip of Rocky Point and north of Priscilla Beach.
 Like many similar plants, it was constructed by Bechtel, and is powered by a General Electric BWR 3 boiling water reactor inside of a Mark 1 pressure suppression type containment and generator.
 It has a 690 MW production capacity.
 Pilgrim Station produces about 14% of the electricity generated in Massachusetts.
Shchi (Russian: щи ; ] ) is a Russian style cabbage soup.
 When sauerkraut is used instead, the soup is called sour shchi, while soups based on sorrel, spinach, nettle, and similar plants are called green shchi (Russian: зелёные щи , "zelyoniye shchi").
 In the past, the term "sour shchi" was also used to refer to a drink, a variation of kvass, which was unrelated to the soup.
Cyathea fulgens is a species of tree fern native to Cuba, Jamaica and Hispaniola.
 It forms part of the complex centered on "Cyathea woodwardioides" comprising six very similar taxa from the Greater Antilles.
 The other five species are "Cyathea crassa", "Cyathea grevilleana", "Cyathea portoricensis" and "Cyathea tussacii".
 Large and Braggins (2004) note that this group is known to cross with members of the "Cyathea minor" complex.
 In the wild, "C. fulgens" also forms hybrids with "Cyathea brooksii".
