The Samydaceae, a tropical and subtropical family, includes 17 genera and about 400 species, the majority of
which are found in the tropics. At the present time, two genera, Casearia and Homalium, with approximately 18
species, one variety and one form are known in this country. Most members of this family prefer the moist
atmosphere of rain forests in southern latitudes, consequently they are more abundant and more luxuriant in the
island of Hainan, where 11 species occur, amounting to about 60% of the known elements of this family so far
accredited to our region. The number of species recorded for provinces on the mainland are: Kwangtung 9,
Kwangsi 6, Yunnan 3, Fukien 2. Only one species has been definitely recorded for the island province of
Taiwan and Hunan.
The Chinese species are mostly shrubs, rarely medium sized trees, scattered individually so that they do not
constitute dominant components in forest formations. In Hainan, a few species, such as Casearia membranacea
Hance, Homalium hainanense Gagnep., while moderate in size, yield wood of fair quality which is suitable for
railroad ties, house-building and ship-construction. The wood of Homalium stenophyllum Merr. and Chun is
strong and tough, used locally for manufacturing agricultural implements.
In the present review of the Chinese Samydaceae, in preparation for a Flora of Hainan, 7 new species have been
proposed, 6 in Homalium, 1 in Casearia, namely C. yunnanensis. The new additions amount to an increase of
50% over previously known records.
