A MORPHOLOGICAL STUDY ON FIFTEEN MEDICINAL PLANTS GROWN IN BANGLADESH OPEN UNIVERSITY CAMPUS (Pages : 5 - 15)
M.A. TALEB AND A.H.M. SHAMIMThe research focuses the understanding on morphological features of 15 medicinal plants for their authentic identification, popularization of cultivation, necessity, future scientific study, sustainable uses and useful information. The lowest growth rate was recorded 08.0 cm in arjun tree and the highest was 95.0 cm in neem tree. The highest number of primary branches (14) in arjun tree identical to orange jessamine, secondary branches (30) in gynura and tertiary branches (168) in arrowleafsida were recorded. The growth habit of majority of the plants were erect and some were of spreading. The canopy diameter was found the lowest 25 cm in arjun tree and the highest 160 cm in arrowleafsida. Wild almond and curry leaves tree did not show any branches. Among the remaining plants, the lowest branch density (02) was recorded in cedrela and the highest (188) was in arrowleafsida. The lowest stem diameter was found 0.64 cm in shalpani and the highest was 3.18 cm in wild almond tree. Different stem color was recorded. No plants showed stem hairs. The shape of leaf was found lanceolate, digitate, odd-pinnate, ovate, even pinnate, elliptic and linear. The shape of leaf apex in most of the plants was acute and other plants showed pointed, caudate, acuminate, obtuse and cordate. The acute shape of leaf base was found (5) followed by rounded and cuneate 4 of each and the other two showed oblique type leaf bases. Six plants had entire shaped leaf margin followed by undulate (5) shape, but other plants showed serrate, serrulate and dentate. Thirteen out of fifteen medicinal plants had green colored leaf, but the other two had dark green. The highest length of leaf was recorded 35.0 cm in cedrela. But the lowest was 1.8 cm in shalpani. The leaf width was found highest 30 cm in cedrela, but the lowest was 1.0 cm in arrowleafsida. The highest length of petiole was found 23.0 cm in wild almond tree, but the lowest 0.5 cm in pomegranate, arjun and glory bower. The leaves, roots, stems, barks, flowers, fruits and seeds of the medicinal plants perform to control different diseases e.g. headache, toothache, diarrhea, dysentery, fevers, coughs etc. The size, type and nature of the plants were also studied to comprehend the morphological characters.
