Sagittaria montevidensis

Sagittaria montevidensis is a species of flowering plant in the water-plantain family Alismataceae. Common names include giant arrowhead and California arrowhead. Sagittaria montevidensis is widespread in wetlands of North America (United States, Canada, Mexico) and South America (Brazil, Bolivia, Ecuador, Peru, Argentina, Chile, Paraguay, Uruguay). In North America, the distribution is disjunct, primarily in a wide area from West Virginia to Texas to South Dakota, but with isolated occurrences in New Brunswick, Maine, Connecticut, New York, New Jersey, California, Florida and Alabama It is reportedly naturalized in Spain, Tanzania, and the Island of Java in Indonesia. Habitat. It grows preferentially at the edges of ponds, in shallow and often only temporarily existing waters. Subspecies. Sagittaria montevidensis subsp. calycina (Engelm. ) Bogin (syn. Sagittaria calycina Engelm. ) - United States, MexicoSagittaria montevidensis subsp. montevidensis - South AmericaSagittaria montevidensis subsp. spongiosa (syn. Sagittaria calycina var. spongiosa Engelm. , Lophotocarpus spongiosus (Engelm. ) J. G. Sm. ) - Mid-Atlantic and Northeastern United States, New Brunswick in CanadaSagittaria montevidensis is a robust, stemless, rhizomatous, aquatic plant. The young ribbon-like leaves grow submerged, while the leaves of older plants emerge above the water surface. The leaves are sagitatte and glabrous, up to 28 centimeters long and 23 centimeters wide. Its terete, spongy petioles may reach a length of more than 0. 75 m (2. 5 ft) and are up to 3 inches thick. Inflorescences are typically shorter than the leaves and decumbent. Flowers are in whorls or pairs at nodes and have a diameter of two to three centimeters. . They have three petals, each of which is white with a striking wine-colored stain, and three green sepals. The thick pedicels are as long as 5 cm (2. 0 in). Flowering occurs from June to September.

Dwarf Saltwort

Salicornia bigelovii

Salicornia bigelovii is a species of flowering plant in the amaranth family known by the common names dwarf saltwort and dwarf glasswort. It is native to coastal areas of the eastern and southern United States, as well as southern California, Belize, and coastal Mexico (both the east and west coasts). It is a plant of salt marshes, a halophyte which grows in saltwater. It is an annual herb producing an erect, branching stem which is jointed at many internodes. The fleshy, green to red stem can reach about 60 cm in height. The leaves are usually small plates, pairs of which are fused into a band around the stem. The inflorescence is a dense, sticklike spike of flowers. Each flower is made up of a fused pocket of sepals enclosing the stamens and stigmas, with no petals. The fruit is an utricle containing tiny, fuzzy seeds. The southern part of the species range is represented by the Petenes mangroves of the Yucatân, where it is a subdominant plant associate in the mangroves. This plant is gaining scientific attention for its potential to serve as an oil crop that can be grown in desert environments and maintained with water containing high levels of salts. It is the source of salicornia oil. The plant is up to 33% oil. The oil contains up to 79% linoleic acid and is functionally similar to safflower oil. It can be used as a cooking oil and a replacement for more valuable oils in chicken feed. Domestic animals can be fed the plant as a forage. The plant could also be a source of biofuel.
