| Abstract: |
arcissus tazetta L. and Pancratium maritimun L. are ornamental bulbous herbs belonging to the family flidaceae; both are usually termed in Egypt by the public reissus. These plants contain mainly alkaloids, volatile flavonoids, lipids and carbohydrates. The pharmacognostical study including the botanical and chemical studies of the different organs of these two tlants were found to be unsufficient. For this reason the present work was planned aiming filling the gaps in. the study of the different organs the two plants and for finding out a means of different— IlatiOfl between them. I, I. Botanical Study Macromorphology :Narcissus tazetta I. and Pancratium maritimum L. are <beautiful, popu’ar perennial Amaryllidaceous herbs, nearly similar to each other; having small ovate ti.rnicated bulbs, adventitious fibrous root systems, radical linear leaves and odorous flowers arranged in umbells.BulbsBulbs of both plants a:re tunicated, ovate in shape,a basal disk like stems and numerous adventitiousous roots. In Narcissus tazetta L. the bulbs are usually :1ler than those of Pancratium marimum L.; being nearly ].f its size; attaining 2 to 4 cm in diameter and 3 to 5 cm leugth. Bulbs of both plants have slight odour and dis— jmct bitter taste.Foliage leavesFoliage leaves of both plants are, radical, simple,to 7 in number. They are sessile, linear in shape. Leaves lof both plants are coriaceous when fresh and brittle when dry. They are odourless and possess a persistent bittertaste. In Narcissus tazetta L. the foliage leaves are usually smaller than those of Pancratium maritimu. L.; being nearly ‘half its size; attaining 25 to 40 cm in length, and 1 to 1.8 cm in width. The foliage leaves of Pancratiummaritimum L. are slightly spirally twisted in appearance.3- The Root :Roots of both plants are formed of fibrous root systems, faint whitish—yellow in colotw. They are flexible when fresh and brittle when dry, odourless, but have a persistent bitter taste. In arcissus tazetta L. they measure from 3o 6 cm in length arid about 0.1 cm in diameter, whilein paricratium maritimum L. they are distinctly larger in size; airiing from 8 to 32 cm in length, and about 0 .3 to 0.5 cm diameter. micromorphology 1- Bulbs : The inner and outer epidermal cells of bulbs of both nbs are covered with thin smooth cuticle.
