Vulnerable flora species in Natural Park Bucegi Fam. Gramineae Sesleria rigida Heuff. ex Rchb. Synonymy: Sesleria haynaldiana Schur, Sesleria filifolia Hoppe Chorology: Cheile Brateiului, Cheile Zanoagei, Cheile Tatarului Area: Bulgaria, Greece, Romania Cenologic habitat: in the mountain and alpine zone, on meadows on steep slopes, sunny and shadow rocky lands on calcareous substrate Limiting factors: endemic species Conservation measures: species located under Natural Park Bucegi protection area References: 1. Monica Neblea (2005), 2. V. Alexiu (2008), 1. Andreea Matei (2013). Vulnerable plants analysis Through taxonomical analysis (Fig.2), was made the floristic inventory from the studied area, which contains 18 taxa, assigned in 17 genres and 13 families. The floristic abstract reveals that the biggest percentage is held by families: Ranunculaceae (2 sp.), Compositae (2 sp.), Orchidaceae (3 sp), the rest of the families being represented by a single species. Fig. 2: The number and families of vulnerable species identified in the studied area The bioforms spectrum analysis (Fig.3) shows the high percentage of hemicryptophyte (44%), which are the main builders of grassy carpet of forest, alpine and subalpine meadows and also of saxicole vegetation. The chamephytes hold a significant percentage (11%), often found especially in subalpine floor and geophytes (17%) represented by ephemeral species. From total categories of biological forms, annual and biennale therophytes have 8% frequency; this large percentage reveals the existence of a high pressure exercised by anthropical factors over analyzed territory. 103 Primulaceae Gentianaceae Thyme leaceae Saxifragaceae Ranunculaceae Polygonaceae Poaceae Orchidaceae Grossulariaceae Ericaceae Compositae Campanulaceae Brassicaceae Apiaceae
