Assistant Professor Dr Wilawan Promprom and Assistant Professor Dr Wannachai Chatan, SCIMSU researchers from the Department of Biology at Mahasarakham University, published a new article, \u201cNew Medicinal Plant Variety of Trichosanthes tricuspidata<\/em> Lour.

ABSTRACT<\/strong>: Objectives<\/strong>: This research was carried out for describing, illustrating and treating a new medicinal plant variety in the genus Trichosanthes<\/em>. Methods<\/strong>: This research was carried out by collecting plant specimens in the Northeastern Thailand. Morphological characters were studied and compared with the closely related taxon and taxonomic literatures. Results:<\/strong> T. tricuspidata<\/em> subsp. rotundata<\/em> var. longirachis<\/em>, was found. This plant is described and illustrated here and treated as a new variety. It differs from the other of T. tricuspidata<\/em> subsp. rotundata<\/em> by having the following combination characters: Comparatively stout herbaceous climber up to 20 m long, tendril 3\u20135-brached, probract obovate with obvious glands, mature blade unlobed or 3-shallowly lobed with 1-2 short angles, blade not deeply lobed (unlobed blade found in juvenile plants), blade size 5-11 cm diameter and raceme rachis length 10\u2013130 cm. Its fruits and seeds were used as medicinal parts. Conclusion: <\/strong>Totally, three subspecies and four variety of T. tricuspidata<\/em> in Thailand have been recorded so far. Important comparative morphological characters with some closely related variety are discussed. The local people used it as medicinal plant.<\/p>\n\n\n\n

Type<\/strong>: THAILAND, Kanthawichai district, Maha Sarakham Province, location 48Q 0312952 UTM 1796680, alt. 140\u2013150 m, 18 June 2013, W.Chatan 1626 (Holotype: MSUT!)<\/p>\n\n\n\n

Diagnosis:<\/strong> The new plant variety differs from T. tricuspidata<\/em> Lour. subsp. rotundata<\/em> W.J.de Wilde and Duyfjes var. rotundata<\/em> by having the following combination of characters: comparatively stout climber up to 20 m long, tendril 3\u20135-brached, probract obovate with obvious glands, mature blade unlobed or having 3-shallowly lobed with 1-2 short angles, not deeply lobed (unlobed blade found in juvenile plants), blade size 5-11 cm diameter and raceme rachis length 10\u2013130 cm.<\/p>\n\n\n\n

Flowering and fruiting:<\/strong> Flowering of male flowers in April\u2013August. The flowering of female flowers is unknown. Fruiting in July-September.<\/p>\n<\/div>\n\n\n\n

Distribution:<\/strong> T. tricuspidata subspecies rotundata<\/em> var. longirachis<\/em> is endemic to Thailand and known from Ban Phai District, Khon Kaen Province, and Kanthawichai District, Maha Sarakham Province, Northeastern Thailand.<\/p>\n\n\n\n

Ecology:<\/strong> This species grows in dry dipterocarp forest or near roadside at an elevation of 130\u2013150 m. It climbs on shrubs or trees in slightly dense or open areas.<\/p>\n\n\n\n

Vernacular name:<\/strong> Tam Lueng Kok and Khi Ka (\u0e15\u0e33\u0e25\u0e36\u0e07\u0e42\u0e04\u0e01\u0e2b\u0e23\u0e37\u0e2d\u0e02\u0e35\u0e49\u0e01\u0e32)<\/p>\n\n\n\n

Etymology:<\/strong> The name of variety is named after the distinct morphology of this plant, i.e the very long rachis of inflorescence.<\/p>\n\n\n\n

Uses:<\/strong> The local people use this plant variety as a medicinal plant. Its fruits and seeds were used as purgative. The seeds were used as laxative.<\/p>\n\n\n\n

Additional specimen examined:<\/strong> W.Chatan 1630 (MSUT), THAILAND, Ban Phai District, Khon Kaen Province.<\/p>\n\n\n\n
