ABSTRACT
FLORA OF VIETNAM 19
THEACEAE D. Don, 1822
(2 subfamilies, 5 tribes, 11 genera, 124 species, 15 varieties and 2 forma)
INTRODUCTION
The family Theaceae includes about 29 genera and 550 species, which is distributed in tropical and subtropical regions of the two hemispheres. The most basal representations are concentrated in Asia, especially in China and Indo-China. Vietnam has 11 genera, 124 species, 15 varieties and 2 forma, distributed in 40 among 63 provinces and cities, chiefly in the mountainous regions. The economic value of Theaceae is well-known, chiefly in drinking, giving tannin, some wood and drugs.
The studies about the taxonomy of Theaceae began very soon as C. Linnaeus (1753), Moech (1974), D. Don (1822), etc. After that, G. Bentham & J. D. Hooker (1862-1887), V. H. Heywood (1993), H. Melchior (1964), Phedorov (1981), A. Takhtajan (1973, 1987, 1996) etc. The revisory studies on Camellia were carried out by J. R. Sealy (1958), H. T. Chang & B. Bartholomew (1984); T. L. Ming (1999); and the genus Eurya was worked out by C. E. Kobuski (1947), L. K. Ling (1966) etc.
In Vietnam, several foreign authors also studied Theaceae such as J. Loureiro (1790), J. B. L. Pierre (1887), C. J. Pitard (1910), F. Gagnepain (1943, 1948). Besides, a lot of studies were carried out by the local taxonomists who updated the taxon status and documented several new species for the flora of Vietnam such as Le Kha Ke (1970), Pham Hoang Ho (1970, 1991, 1999), Tran Dinh Ly (1984), Nguyen Tien Ban (1997), Nguyen Tien Ban & Nguyen Huu Hien (2003), Trần Ninh (1998), Tran Ninh & N. Hakoda (1998), J. C. Rosmann (1997), etc.
In addition, there were several studies carried out related to the economic importance and uses of Theaceae members in Vietnam, such as Do Tat Loi (1986, 2000), Vo Van Chi (1997, 2012), Do Huy Bich & al. (2004), etc.
In the countries adjacent to Vietnam, studies on taxonomy of Theaceae were also carried out by several authors such as T. L. Ming (1997, 1999), H. T. Chang (1954, 1981, 1991, 1998), L. K. Ling (1996, 1998) in China; W. T. Thiselton Dyer (1874) in India; etc.
Flora of Vietnam, volume 19 on Theaceae D. Don is a full and systematic study on taxonomy. It is an output of decades of investigation, collection and research carried out in different parts of the country, especially at the places which are suitable habitat for the species of Theaceae. At the same time, authos also studied specimens and documents housed at different herbaria such as Institute of Ecology and Biological Resources (HN); Hanoi University of Science, Vietnam National University, Hanoi (HNU); Forest Inventory and Planning Institute (HNF); Institute of Tropical Biology, Ho Chi Minh City (VNM); Hanoi University of Pharmacy (HNPI), Institute of Medicinal Materials, Hanoi (HNPM); Botanical Institute Komarov, Leningrad (St. Peterburgh), USSR (LE) and Museum Natural d’Historie Naturelle, Paris, France (P).
This volume comprises of about 360 pages dealing with different systems of classification studied for Theaceae in Vietnam. It also mentions the diagnostic characters of every species of this family found in Vietnam, inventory of classification systems and keys to taxa. Accepetd Latin names for every taxon along with synonyms, morphological characters, type, ecological and biological characters, distribution inside and outside the country, specimens examined, economic value, notes (if any) are provided.
In addition, there are 117 figures of different species and 18 supporting coloured photo, keys to identification, accepted Latin and Vietnamese names, along with references. Besides, the introductory part in dealt in English (Introduction and Keys to taxon).
At the end, references, figures, coloured images from other authors are also provided.
Index to Taxa of Theaceae in Vietnam (provided as per an accepted classification systems).
