Floristic aspects of the Hills of Camena village / Ovidius University Annals, Biology-Ecology Series 14: 45-54 (2010)
Spermatophyta [6], Flora Europaea [7, 8] and
Flora României [4]. The life forms, floristic
elements and ecological categories have been
established on the base of the synthesis works
Conspectul florei cormofitelor spontane din
România [9] and Flora ilustrată a României.
Pteridophyta et Spermatophyta [6]. The rare and
threatened plant species was done according to the
Romanian Red List [10] and the Romanian Red
Book of the vascular plants [11].
3. Results and Discussions
The floristic researches carried out on the hills
of Camena village have lead to identification of 178
vascular taxa (168 species and 10 subspecies)
(Table 1). Taxa found in the studied area belong to
46 families and 38 classes of Spermatophyta
Divisio. The following families are well
represented as number of taxa (Fig. 1): Asteraceae
(12,35%), Lamiaceae (10,67%), Poaceae (9,55%),
Rosaceae si Brassicaceae (5,05%), Liliaceae,
Caryophyllaceae si Fabaceae (cate 4,49%),
Apiaceae (3,93%), Boraginaceae (3,37%),
Ranunculaceae (2,80), Geraniaceae (2,24) and
Scrophulariaceae (1,68%).

number of species (AST-Asteraceae; POA-
Poaceae; LAM-Lamiaceae, ROS-Rosaceae; LIL-
Liliaceae;CARY-Caryophyllaceae; FAB-Fabaceae;
API-Apiaceae; BRAS-Brassicaceae;
RAN-Ranunculaceae; BOR-Boraginaceae;
GER-Geraniaceae; SCR-Scrophulariaceae)
From the point of view of the biological forms
(Fig.2), the dominant ones are the
46
hemicryptophytes (42.13%) and the annual and
biennial terophytes (35.95%), present especially in
the steppe meadows. Poorly represented are the
phanerophytes (9.55%), which are included in
forests (with Quercus petraea subsp. dalechampii,
Quercus pubescens, Carpinus orientalis, Fraxinus
ornus, Prunus mahaleb, Tilia tomentosa) and
bushes (with Crataegus monogyna, Prunus spinosa,
Cotinus coggygria, Ligustrum vulgarae, Rosa
canina, Cornus mas) in the investigated area.
The category of phanerophytes also includes
alien species encountered in these hills, some of
them invasive or potentially invasive (Robinia
pseudacacia, Ailanthus altissima, Elaeagnus
angustifolia). The geophytes (7.30%) and the
camephytes (5.05%) are perennial species found
especially in the grassy blanket from forests or
forest edges.

(H-hemicriptofite; TH-therofite; PH-fanerofite;

Among the floristic elements (Table 2 and
Figure 3), the dominant species are the Eurasian
(35.39%) and Pontic (26.40%) ones, followed at
great distance by other categories of geoelements:
European (8.98%), Central-European (6.17%),
Mediterranean and sub-Mediterranean (6.17%),
Balkan (5.61%), circumpolar (1.68%), Atlantic-
Mediterranean, Taurean-Balkan, Carpatho-Balkan-
Caucasian, and endemic (each with 0.56%).
The large proportion of Pontic species reflects
on the one side the dominance of the steppe
meadows in the studied area, and on the other side,
the nearness of the Razelm-Sinoe lagoon complex
(located approx. 10 km east), which belongs to the
Pontic biogeographic region. Among the categories
