SOME NOTES ON ETHNO-BOTANY IN THE NEW TERRITORIES OF HONGKONG
ARMANDO DA SILVA*
There is an old Cantonese proverb that goes "Kau shan yak shan, kau shui yak shui, (*****). When translated it means "When in the hills, live off the hills, when on water, live off the water". In many of the smaller villages of the New Territories, and especially among the more isolated coastal ones, this maxim is still practised to some extent in everyday life. Most of the older villagers possess an intimate knowledge of various qualities of common plants. Many plants that thrive in the neighbourhood of settlements owe their survival because they have some useful or medicinal qualities to offer, which distinguish them from mere brushwood destined for the kitchen stove.
A source of income for coastal settlements derives from economic activities related to the use of beaches by Tanka and Hoklo fishermen for careening their boats. These fishermen also use the beaches to dry and mend their nets. As these tasks must be done frequently to prevent rot and tear, many villagers often find it profitable to provide services for the fishermen. Large vats are installed so that salt can be boiled out of the nets. Other vats are used for dyeing and for applying net preservatives. Most nets are made from imported ramie or coconut coir fibers. However, a plant common to many coastal villages is often used to make fibers for fishing nets. This is the Agave, called by Tanka and Hoklo fishermen poh lo ma ("pineapple hemp"). It is also known by its other Chinese name of lung sit lan (⃧ "dragon tongue orchid") because of its high flowering stamen. The Agave thrives on drier sandy soils near beaches and does not seem to be affected by salt water spray. After the spines are removed from the plant, fiber is extracted by pounding and retting. The juice is often used as an insecticide and the saponin content as a form of soap for washing clothes.

His article "Fan Lau and its Fort: an Historical Perspective" appeared at pp. 82-95 of last year's Journal. Mr. da Silva states that the present article refers, in particular, to some coastal settlements in Lantau and the Saikung Peninsula where he spent much time visiting and observing people and things from October 1962 to September 1963, and again in the summer of 1964.
