For example, according to the inflorescence and fruits, farmers in the Hainan divide areca into long-pedicle species and short-pedicle species. Areca nut yield, alkaloid species and content, medicinal value and biological and ecological characteristics of different varieties are greatly different.
Ecological environment: The tree was native to Malaysia, Areca catechu is mainly distributed in Southeast Asia, tropical Asia, and parts of Europe, in the Pacific region it is mainly distributed in Papua New Guinea, Solomon Islands, Fiji, Vanuatu and Micronesia, scattered in the skin's island, in the Mariana Islands and the Marshall Islands, Hawaii islands Areca catechu is only used as ornamental planting.

The optimum temperature is 10-36 °C (Celsius, or 50~96.8 degrees Fahrenheit), the minimum temperature is not less than 10 °C (Celsius, or 50 degrees Fahrenheit), and the maximum temperature is not more than 40 °C (Celsius, or 104 degrees Fahrenheit). It can grow well in areas with an altitude of 0~1,000 meters and an annual rainfall of 1,700~2,000 mm.
Characters of herbs: Seeds are oblate or conical, the top is blunt and round, the base is flat and wide, the height is 1.5~3 cm, and the base diameter is 1.5~3 cm. The surface is yellowish-brown to dark brown, with slightly concave light reticulated lines, occasionally with silvery-white endocarp patches or pericarp fibers, with concave pits in the center of the base (the micropyle part) and a large light-colored navel beside it. The texture of the herb is extremely hard, marble-like lines can be seen on the cut surface, which is formed by the reddish-brown seed coat and outer endosperm mistakenly inserted into the white-like inner endosperm. There are gaps inside the longitudinal section of the micropyle, and there are embryos smaller than shrinkage. The herb has a slight odor, it tastes slightly bitter. The herb of better grade is big, heavy, hard, and unbroken.
In 2003, the international center for research on cancer published the conclusion that "areca nut itself is the first type of carcinogen", which is the authoritative conclusion after collecting hundreds of areca nut research reports from seven countries and regions, including Taiwan, and Pakistan. This conclusion also tells people, often eat areca nut may cause cancer. Besides, a 2010 study by the Taiwan institute of health showed that the percentage of oral cancer cases in the public could be attributed to betel nut chewing (38%) and smoking (31%). The researchers also called for people to quit betel nut and quit smoking to prevent oral cancer.
