1987 10(1) 9-13 Peter Matthews Wild taro and the context of cultivation (Buy)
ABSTRACT: Two historical questions of primary importance are, first, what was the natural distribution range of taro before its use by humans? Secondly, in what areas has cultivation of local indigenous taro taken place? The present distribution of taro is the outcome of selection and transfer by humans, as well as natural selection dispersal.

ABSTRACT: Although aroids are best known as food plants, a large majority of the wild and cultivated species in Vietnam have medicinal uses. Detailed studies of optimal growth conditions and effectiveness for medicinal use are needed for all of these plants. Ethnobotanical and practical studies also needed for sustainable management of wild aroid populations. This paper highlights the general scarcity of information on medically useful aroids.

ABSTRACT: Economic aroids are likely to have an increasingly important role in food security and agro-biodiversity. Vietnam is located within the Southeast Asian region that appears to be a cradle of origin for aroid crop species. Aroids have had long cultural and economic history among the diverse ethnic communities within Vietnam. There is not only a wealth of biological diversity among the economic aroids of Vietnam, but also a wealth of local knowledge concerning the planting, care, harvest, storage and use of aroids. The Plant Resources Center (former Plant Genetic Resources Center) is a focal point of the National Plant Genetic Resources conservation network in Vietnam and has conducted field surveys, collecting missions, and conservation efforts for economic aroids and related knowledge in Vietnam. We will introduce the previous history, study, and utilisation of aroid collections at the Plant Resources Center. The Center currently maintains 600 accession of Colocasia, 100 accessions of Xanthosoma, 16 accessions of Amorphophallus, 12 accessions of Alocasia and more than 32 unidentified accessions. We will also discuss aroid conservation strategies for Vietnam in the future.

2015 38E(1) 153-176 Peter Matthews, Van Du Nguyen, Daniel Tandang, E. maribel Agoo, Domingo A. Madulid Taxonomy and ethnobotany of Colocasia esculenta and C. formosana (Araceae): implications for the evolution, natural range, and domestication of taro (Read)
ABSTRACT: A critical problem for the taxonomy of taro (C. esculenta), and for understanding the evolution and domestication of this species, is that there is no way to recognise, by simple visual inspection, a wild population of taro as part of a natural distribution. This is because people throughout Southeast Asia have long used wild taro as a vegetable for human and animal consumption (as food and fodder). The example of C. formosana Hayata is introduced here because our observations so far indicate that this is a naturallydistributed wild species throughout its known range, despite its close phenotypic similarity to C. esculenta. To learn about the evolution, natural range, and domestication of taro, closer study of C. formosana is recommended.
