Festuca. Lately the species of Festuca arenicole in the Danube Delta area and the
coastline were more thoroughly explored. Apart from F. arenicola (Prodan) Soó – of different
taxon positions (Bas.: Festuca pallens Host subsp. arenicola Prodan; Festuca cinerea
Vill. subsp. arenicola (Prodan) Beldie; Festuca vaginata Waldst. & Kit. var. arenicola (Prodan)
Soó & Simon) with the synonim: Festuca pallens Host subsp. mamaiae Prodan; Festuca
pallens Host var. mamaiae (Prodan) Beldie; taxon ackowledged in Flora Europaea
(MARKGRAF-DANNENBERG 1980: 147) CIOCÂRLAN (2009: 1009) mentions it on the coastline
sands in Rm and NE Bulgaria (where we collected it in 2008, from the coastline sand at
Duranculac HGN); other species indicated in our country:
164. Festuca beckeri (Hack.) Trautv. (incl. subsp. beckeri) (syn. Festuca ovina L. subsp.
beckeri Hack.) /POA/ – according to our researchers, it is also encountered in our country
(DIHORU 1987): BR: Movila Miresei; TL: Delta Dunării: Letea, Grindul Letea ut Cardon;
CT: Mamaia (DIHORU 1987). According to Ciocârlan (2009: 1009) the species does not
grow in Rm. After Soó (1955: 198), F. beckeri is a pontic and aralocaspic element while F.
polesica is a northern Baltic one (SOÓ 1955: 197). I believe that F. arenicola grows on the
coastline and continental sands in the regions of lower Bârlad and SW Brăila, while F.
beckeri is a pontic and aralocaspic element and F. polesica is a Baltic element; they may
be vicariant taxa in the affinity area of the F. vaginata.
165. Festuca polesica Zapał. (Festuca beckeri (Hack.) Trautv. subsp. polesica (Zapał.)
Tzvelev) /POA/ – mentioned by us on the sands in the region of lower Bârlad, Hanul Conaki
(CIOCÂRLAN 2009: 1009). Reservatio "Hanul Conaki" (DIHORU 1987). Iveşti (CIOCÂRLAN
1998: 20). In silva Drăgăneşti (DIHORU 1987). In silva Torceşti; Blăjerii de Sus; inter
Diechieni–Călmăţui–Hanul-Conaki (OPREA 1998). TL: Delta Danubii, in silva Letea (ROMAN
1992: 51). Nevertheless 6000 years ago the Black Sea coastline spread up to Hanul-Conaki
area and to the sands SW of Brăila and many plants here seem relics of that period (Aeluropus
littoralis, Hymenolobus procumbens, Juncus maritimus, strictly littoral plants).
166. Filipendula ulmaria (L.) Maxim. subsp. picbaueri (Podp.) Smejkal /ROS/ – SB: dextra
rivuli Pârîul Strâmb, prope confluentio cum rivulum Pârîul Ruşciorul (SCHNEIDER-
BINDER 1976). Chorology: Atlas Fl. Eur. map 3284 (KURTTO et al. 2004: 38).
Fraxinus L. More taxa and fito-geographical information was gathered regarding
the ashtree in our country. Still we don’t have a clear unitary point of view about the ashtrees
in our country. More and more botanists and still more sylviculture specialists indicate the
plain regions, especially the ones in the Romanian Plain- Fraxinus excelsior, though this
taxon grows in regions of hills and mountains and moderate wet areas. It is interesting that a
peasant in the Plateau of Mehedinti, at the foot of the Mehedinti Mountains (Giurgean, Giurgeni
- Isverna) knew that and when asked if he could show me a “black” ashtree he answered
it was quite scarce there in that chalky stone area and that it only grew in the mountains.
There is also a PhD diss. at the Faculty of Sylviculture Univ. Brasov, which unfortunately I
could not see. Flora Europaea brought some clarifications concerning the ashtrees (AMARAL
FRANCO & ROCHA AFONSO 1972: 53) but not ultimate ones. Now it is known that the Fraxinus
angustifolia Vahl is a plant with leaves without hairs, mainly growing in western areals. Other
taxa replace it in plain regions like ours. One of them is:
