Arapawa Island
The origin of the Arapawa sheep is not certain but they have been on the New Zealand island of Arapawa for at least 135 years. They are considered a rare and endangered breed. There are many theories on the origin of the sheep. One theory implies that they are Middle Eastern breed introduced by the whalers. Another theory suggests that they originated from Austalian Merinos. The most intriguing theory is that the sheep landed on the Arapawa island from a Spanish galleon as far back as the 1500s. According to the Maori legend on the island, the Spanish galleon sailed into a bay 400 years ago and befriended the people. But when the Spaniards stole the Maori Women, the men turned upon them and burned the ship. The ancestors of the Arapawa sheep escaped the wreck and swam ashore. The sheep are prehistoric looking wild sheep with fine black wool and white points. They are also horned.

The stem is swollen at the base and throws out creeping stolons or runners, which produce globose winter tubers one cm in diameter, composed almost entirely of starch. The leaves are borne on triangular stalks that vary in length with the depth of the water in which the plant is growing. The leaves don't lie on the surface of the water, but stand above it. The leaves are large, glossy and shaped like an arrowhead. The flower stem rises directly from the root and bears several rings of buds and blossoms, three in each whorl. Each flower is composed of three outer sepals and three large petals which are white in colour with a purple base. The root of the arrowhead has long been eaten by the Chinese, Japanese and North American Indians.

Arrowroot

The flowering stem reaches a height of two meters and bears creamy flowers at the ends of the slender branches that terminate the long peduncles. They grow in pairs. The numerous, ovate, glabrous leaves are from 5 to 25 cm long with long sheaths often enveloping the stem. A starch is extracted from the rhizomes and used in cooking and in herbal medicine for treating scorpion and spider stings.
