Danube plain, near the Miiselievo village, Nikopol district, rocky niche in Kainaka

locality, western slope, 180 m a.s.l., N 43° 37’ 3" E 24° 5 Г 58", on limestone, with

spores, 25.10.2005.

Specimens examined

;

SOM - 583, Vratza Balkan ad stationem Lakalnik, SOM-157583, Vratza Mt,

Stojanovo village, on open limestone rocks, 25.05.1968; V. Velcev; SOA -257, on

limestone rocks above the village o f Lakatnik, 30.05.1926, N. Stojanov; SOA-258, near

the St Ivan Pustinmk monastery, Vratza region, 03.09.1935, B. Stefanov.

For the distribution of this taxon Greuter et al. (1984) and Tulin et al. (1993)

mention South-east and South-central Europe extending locally westwards to North­

eastern Spain,

Димитров (ред.) (2001) considers this species as an Alps - Balkan geoelement.

In our opinion this determination is incorrect taking into account the area presented by

Davis (ed.) (1965), Brownsey (1976) and Tutin et al. (1993).

The distribution of

Asplenium lepidum

is concentrated in Southern Europe and the

localities known can be found in the Allas Florae Europaeae (Jalas, Suom inen , 1972)

and in Brownsey (1976).

Until now the localities in Bulgaria were reported from the floristic region

Western Stara planina (Ахтаров , Й орданов , 1963, Стоянов и д р ,: 1966,

Д елипавлов (ред.), 1983, 1992; Андреев , 1992; Д елипавлов , Чешмеджиев

(ред.), 2003).

According to Урумов (1905) the species is indicated for the area of Eovetch

(floristic region Balkan foothills) cited only by Стоянов, Стефанов (1948). Unfortu­

nately, there are no specimens available in the Bulgarian herbaria

(SO, SOA, SOM

This

information on the chorology o f the species is not considered in die floras (Fig. 2).

From a taxonomical point of view

Asplenium lepidum

is not comprehensively

studied in Bulgaria. There is no data about Hie infraspecific variation and hybridization as

known from other parts of its area (B rown sey, 1976). This author has investigated the

morphological variation of 29 populations of

Asplenium lepidum

complex and considered

the species

Asplenium lepidum

as composed of two subspecies (subsp.

lepidum

and

subsp.

hamscknechtii)

distinguished primarily by gland, sporangial characters and

rhizome scales. He points for the distribution of subspecies

hausscknechtii

the mountains

of Central and Eastern Crete, Southwestern Asia (Turkey), Lebanon, Iraq, Iran and the

Caucasus, between 900 and 2000 m a.s.l. The subspecies

lepidum

, distributed in France,

Italy, Sicily, Austria, Hungary and Crete, grows at lower elevation (300-800 m a.s.l.).

According to Стефанов, Китанов (1962)

Asplenium lepidum

is one of the nine

ferns in the list of the relicts - rare, disappearing or extinct plants in our country. The

species

Asplenium lepidum

is included in The Red Data Book o f Bulgaria (Велев, 1984)

with category' “threatened” and in The List of Protected Species in the Bulgarian Flora,

Supplement 3 in The Law of Biological Diversity (ДВ, 77/2002; 88/04.11,2005).
