COMPARATIVE MORPHOLOGICAL AND HISTOLOGICAL STUDIES OF TALINUM TRIANGULARE (JACQ.) WILLD. AND TALINUM PANICULATUM (JACQ.) GAERTN. (MYANMAR GINSENG)
Abstract
- Talinum triangulare (Jacq.) Willd. (waterleaf, Ceylon ginseng or leaf ginseng) and T. paniculatum (Jacq.) Gaertn. (fame flower, jewels of opar or ginseng jawa) belong to the family Talinaceae. Both were locally known as Myanmar-ginseng. Their leaves have been used as leafy vegetables and roots as medicinal purposes. These were look alike with each other but they have different botanical characters. The root of T. triangulare (Jacq.) Willd was light brown and T. paniculatum (Jacq.) Gaertn was dark brown. T. triangulare (Jacq.) Willd. can easily be distinguished from T. paniculatum (Jacq.) Gaertn.by its triangular peduncle and cymose inflorescence (terete peduncle and paniculate cyme in T. paniculatum (Jacq.) Gaertn). The fruits of T. paniculatum (Jacq.) Gaertn were colorful like jewels while the fruits of T. triangulare (Jacq.) Willd were creamy white with reddish spots and persistent sepals. By using the methods of Trease and Evans (2009), their common histological characters were found as the presence of paracytic stomata, starch grains, calcium oxalate crystals and mucilages in leaves, stem and root. T. triangulare (Jacq.) Willd. can be differentiated from T. paniculatum (Jacq.) Gaertn. by the presence of triangular outline young stem, presence of papillae and rounded xylem vessels.
