NATURAL HISTORY
It is not possible to make any distinction between the trees of Hong Kong and those of neighbouring southern China. The prin- cipal trees in the Colony are pine, Chinese banyan and camphor. A large number of others have been added since the area came under British administration, the most common being casuarina, eucalyptus and flamboyant. The traditional Chinese belief that the disposition of buildings, graves, trees, water and mountains may affect a person's fortune and destiny has done much to preserve fine groves of trees, mostly camphor, banyans and clumps of bamboo around many farms and villages in the New Territories. Some of the mountain slopes, from a distance, seem bare of any plant covering except grass, but on closer observation it can be seen that the water courses are marked by narrow bands of low shrubby growth and scattered trees.
The principal locally-grown fruits include lychee, lung ngan, wong pei, loquat, pomelo, tangerine, banana, papaya, pineapple, custard apple, guava and Chinese varieties of plum and pear. The Portuguese originally introduced the papaya, the pineapple, the custard apple and the guava from South America some time after the foundation of Macau. The tangerine on the other hand is a native of South China which was introduced to the West in the 17th-Century when the Portuguese transplanted it to Tangier, then under their control.
The flora of the Colony is tropical, although at about the northern limit of tropical flora. Alternation between hot humid summers and cool dry winters causes tropical plants to lie dormant during winter and encourages the development of large flowers borne at definite seasons of the year. As a result of this a genus tends to produce a greater wealth of flowers of large size in Hong Kong than it does in other equatorial countries.
Hong Kong is famous for its great variety of flowering plants, many of which are exceptional for the beauty or fragrance of their blossoms. As might be expected most species flower during spring and early summer. Some are easy to place in their correct families- for example, the common wild Gordonia looks like, and is related to, the camellia, and the wild roses are unmistakably roses. But most are not so easy to name. They include a Magnolia, a Michelia
