Leaf, pollen and seed morphology of Eremostachys superba was studied using scanning electron microscopy (SEM) to facilitate identification of this critically endangered medicinal herb. The SEM analysis of the species showed that the leaf of the species is covered with unicellular sparse indumentum of short or longer simple hairs and more pronounced at the margins. The seeds of E. superba are triradiate with triquetrous surface and a tuft of stiff multicellular hairs are present at the apical end. The pollen grains are tricolpate with reticulate surface.Keywords

An ethnobotanical survey of plants used by the 'Rongmai' tribe for the treatment of various diseases was carried out in the Mashkall village, Lakhipur sub-division of Cachar district of Assam. Information on the names of plants, part used and methods of preparation was collected through a questionnaire which was administered by the local herbalists, traditional healers and rural dwellers. Information collected has revealed 16 plant species belonging to 15 families have been found to be utilized for 48 diseases.Keywords

The present study describes seed viability, germination and storage behaviour studies of Eremostachys superba seeds under controlled condition. Eremostachys superba is an endangered medicinal and ornamental herb of North-West Himalaya. Fresh seeds exhibited 98% seed viability and a gradual decrease in seeds stored for different durations at room temperature (RT) and 0-4°C in refrigerator. Maximum germination percentage was observed in seeds stored at 0-4°C for 6-months (35.15%) as compared to the freshly collected seeds (5.7%). Seed germination percentage was enhanced by presoaking the seeds in different concentrations of gibberellic acid. Presoaking of seeds in 400ppm of GA3 was found most effective and 79.32% and 29.43% germination was reported in the seeds soaked in 400ppm GA3 and stored for 6-months at 0-4°C while 29% germination was seen in freshly collected seeds stored at the same temperature and duration. Seeds stored for 6 months at 0-4°C, after presoaking for 24 hours in 400ppm GA3 and sowing in the month of August were found to be most conducive for propagation.Keywords

Pittosporum eriocarpum (Pittosporaceae), commonly known as agni, is an endangered and endemic species of North-West Himalaya and facing a grim situation in the wild. Bark of the species is widely used for the preparation of traditional medicines for the treatment of narcotic, expectorant, bronchitis as well. Microprogation of the species has been carried out by using the shoot tip explant and 93.54% shooting was reported in MS medium supplemented with BAP (5.7 μM) and NAA (1.59 μM) with 24.6 average number of shoots and 5.8 cm shoot length. The in vitro regenerated shoots were shifted to the ischolar_maining medium and quarter-strength basal MS medium fortified with IBA (7.3μM) was observed as the optimum medium for the ischolar_main induction and 95.78% ischolar_maining was reported with 17.4 average numbers of ischolar_mains and 3.6 cm ischolar_main length. After proper development of ischolar_mains (3 weeks) with average ischolar_main length 3.6 cm, 50 plantlets were washed properly and shifted to polythene bags containing mixture of vermiculite and soil (1:1w/v) and maintained in the green house. Initially the pots were covered by the transparent polythene bags to ensure the required humidity content and watered with 1/4 modified Hoagland's solution on alternate day. These acclimatized plants were transferred to the field with survival rate of about 84%.Keywords

Lilium polyphyllum D. Don ex Royle (Liliaceae) is a critically endangered herbaceous perennial, commonly known as white lily or Ksheer kakoli. Bulbs of the plant are of immense medicinal use and have a stringent and anti-inflammatory properties. Over exploitation of the species from the wild and degradation of habitats are posing threats to its existence. In the present study, a protocol was standardized for micropropagation and mass multiplication of the species from scale leaves. Callusing was induced in basal MS medium containing 2,4-D (6.78 μM) and BAP(4.4 μM), where maximum effect (95.32%) was recorded. Maximum shooting (97.45%) was found in the calluses when shifted to MS medium fortified with BAP (4.4 μM), NAA (0.53 μM) and GA3 (20 ppm) with an average of 19.2 shoots/per culture. The well developed in vitro regenerated shoots were shifted to the ischolar_maining medium and 100% ischolar_maining was achieved in half-strength MS basal medium enriched with IBA(9.8 μM). The in vitro regenerated plant lets were shifted to a glasshouse for acclimatization and finally transferred to the open environment with 85% success.Keywords
