Abstract
This investigation was concerned with the reserve area at Msallata (Libya). During the study period (two years), 368 of different plant species were collected and classified. They belong to 223 genera and 58 families. It was noticed that of these plants, 309 species, 181 genera and 49 families were belong to the dicotyledones, while the monocotyledons were represented by 54 species, 38 genera and 5 families. As well as, 4 different species of Gymnosperms belong to 3 genera and 3 families were found. It was noticed that there was a new plant species among the flora of Libya was discovered for the first time in this study. The discovered species was Bupleurum gibrataricum which belongs to the family “Apiaceae”. Morover, 15 different plant species were collected for the first time from the North Western part of the country. Also, some rare plant species were found such as Globularia alyum within the family “Globuluriaceae and Pacncratium maritimum of the family Amaryllidaceae. Also, Cheilanthes vellea (pteridophyte) was collected for the first time from the North Western part of Libya. It was noticed that the vegetation contains 80.1% herbs, 16.3% Shrub and 3.6% Trees. The present research show that soil consisted of sand and clay particles with PH ranged from 8.3 to 8.6 and the total salts did not exceed 89.6 ppm and thus the studied soil was not salinity. Also, this soil was poor in organic matter (0.84% on the average). The ecological study revealed that the vegetation was intensive reached to 78% in some localities of the position area. Also, data indicated that the most dominant species was Stipe tenacissima, followed by Pinus halepensis which was widely spread in location A and B in the East side of the reserve and a few ones were found in the South part. It was found that some Shrub plants were widely spread in the reserve such as Cistus parviflorus and Thymus capitatus. Three different plant habits were found namely: Herbs, Shrubs and Trees. The most dominant herbaceous plants were Linum strictum, Coronilla scorpioides , Anagalis arvensis , Valantia hispida , Plantago spp., Ranunuculus aslaticus and Scilla peruviana. It could be concluded that the most common plant species in the flora of the reserve was Stipa tenacissima, so it could be considered its name as Stipe population.
