Present study has revealed that a good number of species of vascular plants have not been relocated after their discovery. Several species are still restricted to their type localities and there are many species which have been collected only once or twice after their discovery. These species are enumerated in this communication with hope that these may be relocated during survey and exploration work in future.

Kuntze (tea) is one of the most widely consumed beverages worldwide, serving as an essential commodity crop for several developing countries. A bulk of tea's health-promoting properties are attributed to the antioxidant properties of Epigallocatechin Gallate (EGCg), its predominant polyphenol. As a result of these health benefits, tea production and consumption have expanded and promoted tea industries' development globally. Tea cultivation is dependent on a good distribution of rainfall, and the current changes in climate pose a significant threat to its global supply chains. Through the efforts of the International Centre for Tropical Agriculture (CIAT), predictions of future climate changes in the tea growing regions of Kenya between now and 2050 have been generated. A study was conducted to develop models to identify essential tea growing regions that will remain ideal for tea farming and investigate the metabolomic differences between 243 droughts susceptible NonCommercial (NComm) and 60 Commercial (Comm) cultivars. Non-targeted, high-resolution UPLC-MS was used to attain a new profound understanding of the metabolomic multiplicity between the Comm and NComm groups and elucidate their association with tea liquor quality and drought tolerance. Several metabolites, namely argininosuccinate, caffeic acid, caffeine, catechin, citric acid, epicatechin, epigallocatechin gallate, gallic acid, gluconic acid, glucose, maltose, quercetin and theanine, were found to differentiate between the Comm and NComm cultivars. These detected metabolites were linked to improved tea quality and drought tolerance in the Comm cultivars.

C. carpio was administered intraperitoneally with various doses such as methanol extract (0, 0,1, 1, 10 and 100 mg/kg). The immunological parameters of fish blood and serum samples (Neutrophil activity, Lysozyme activity, Serum myeloperoxidase intensity, Serum bactericidal activity, and Serum antiprotease activity) were investigated at 7, 14, 21, and 28 days of post-immunization. Fish had been tested by virulent A. hydrophila for 30 days after treatment and 14 days after infection were identified with mortalities. The findings showed that neutrophil levels, lysozyme activity, serum bactericidal activity, myeloperoxidase activity, and serum antiprotease activity significantly enhanced (p<0.05) compared to untreated control. Mixed dietary algae at 1 and 10 mg/kg lev...

Methods: Fishes were exposure with different CUD in the medium at 0.1% (v/v) as C (Without CUD), T1 (Gir), T2 (Haryana), and T3 (Holstein Friesian [HF] crossbred) for 7 days, a study was conducted. Various growth, food utilization parameters and mortality were examined at 10, 20 and 30 days, respectively, of post-exposure of CUD. Results: The results showed that Gir CUD was a more effective to compare with Haryana and HF crossbred CUD. The maximum growth rate of 0.0160 mg/daywas observed in the L. rohita fingerlings treated with Gir CUD treated fingerlings when compared with control. The maximum feeding rate of 0.0039 mg/body wt/day was observed in the same group. The survival rate of 90% was observed in the same treated group when compared with 60% survival rate in control. Conclusion: Our results indicate that growth parameter and food utilization parameter values were increased significantly due to CUD exposure while comparing with control group. In addition, levels of growth rate, feed conversion rate, percentage increased body weight, and specific growth rate were also increased in the treatment groups.

Its application in Aquaculture has not been explored so far. Hence the present study has been aimed to assess the effect of different breeds of cow urine on the growth and biochemical parameters of Cirrhinus mrigala fingerlings. Urine from different breeds of cow like Haryana, Gir, Jercy was collected. Fingerlings were treated with 0.1% concentrations of different breeds of cow urine for a period of seven days. The control and treated groups were sacrificed on the 30 th day post cow urine treatment and the growth and biochemical parameters were analysed, the results show significant effect of cow urine on the nutrient value of the Indian major carp Cirrhinus mrigala.
