Systematic Exploration of Medicinal Plants: Morphology, Palynology and Leaf Epidermal Anatomy of Medicinal Plants of Upper Himalayas, Pakistan Mir Ajab Khan

The study was aimed to analyze systematic value of morphology, pollen features and foliar epidermal characters for the purpose of identification and delimitation of 26 species of medicinal plants from Upper Himalayas. The highest cell length was observed in leaf epidermal cells of Galium aparine L. in adaxial surface which was 100 µm and of Caltha alba Camb.in abaxial surface which was 85.8 µm and the lowest cell length was recorded in leaf epidermal cells of Ranunculus laetus Wall. in adaxial surface i.e. 35.8 µm and of Geranium wallichianum D. Don. in abaxial surface i.e. 27.5 µm. The highest cell width was reported in leaf epidermal cells of Convolvulus arvenesis L. in adaxial surface i.e. 64 µm and of Caltha alba Camb. in abaxial surface i.e. 85.8 µm and the lowest cell width was observed in leaf epidermal cells of Ranunculus laetus in both adaxial and abaxial surfaces i.e. 19.2 µm and 16.7 µm. The Highest polar and equatorial diameter was recorded in the pollen of Geranium wallichianum D. Don. i.e. 95 µm and 93.5 µm respectively whereas the lowest polar and equatorial diameter was observed in Cynoglossum lanceolatum Forssk. i.e. 6.25 µm and 3.15 µm respectively.
