2014 37E(2) 88-93 Van Du Nguyen, Van Tien Tran, Cong Sy Le, Thi Van Anh Nguyen Rediscovery of Arisaema pierreanum Engl. after 145 Years, and its Current Status (Read)
ABSTRACT: The genus Arisaema belongs to the Arum family – Araceae, which includes about 210 species Govaerts & Frodin, 2002 and is distributed from temperate to tropical areas, mainly in high mountain region. Since established by Martius in 1831, the genus Arisaema was studied by different authors such as Schott (1860), Engler (1920), D. Chatterjee (1955), Hara (1971), Li Heng (1979), Ohashi and Murata (1980), Murata (1984), V.D. Nguyen (1998, 2000, 2002, 2005, 2007). In Engler’s publication, many new species from different countries were described. Among them, Arisaema pierreanum was described based on the collection from Ba Den mountain (Tay Ninh province of Vietnam) made by L. Pierre in his journey in Indochina in 1869. Over 150 years passed without any collection of this species made from other places and with no information published on this species. This paper redescribes the species with more detailed morphological characters, discusses the status of the plant now, and provides images of living plants.

2015 38E(1) 130-142 Van Du Nguyen, Hong Quang Bui, Van Tien Tran, T. Masuno, Peter Matthews Useful aroids and their prospects in Vietnam (Read)
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: The paper includes information on the ecology and biology, distribution and content of glucomannan in tubers of the species Amorphophallus yuloensis H. Li in Vietnam. Amorphophallus yuloensis belongs to a group in the genus with short peduncles. It differs from other species in the group by having a much smaller inflorescence, stout conical appendix and violet blue berries. This is one of five species in Vietnam whose tubers contain high glucomannan content for the food industry. Glucomannan content in its tuber is about 29.2% of dried weight.
