CIOCÂRLAN∗ Summary: the author has analyzed the variability at 3 (three) plant species, namely: Silene supina Bieb., Alkanna tinctoria Tausch, Himantoglossum hircinum (L.) Spreng. After this analyze, there are two new subspecies, depicted here for the first time: Silene supina Bieb. subsp. longicarpa Ciocârlan subsp. nova şi Alkanna tinctoria Tausch subsp. petrosa Ciocârlan subsp. nova. As concerning Himantoglossum, there is a mention that in the flora of Romania is growing H. hircinum subsp. caprinum (Bieb.) Sunderm., and not H. hircinum subsp. hircinum. In this paper, is showed that a synonymyzation of the species S. supina Bieb. with S. spergulifolia (Willd.) Bieb. is an error ! The same is the situation of the synonymy between Himantoglossum hircinum (L.) Spreng. şi H. caprinum (Bieb.) Sundern. Key words: variability - Silene supina - Alkanna tinctoria - Himantoglossum hircinum – Romania. The infraspecifically variability at the vascular plant species in the Romanian flora, has been relied, in a large measure, on the leaf features, i. e. just on that organ which is the most plastic one, as well as the most variable one. The fruit’s features, as well as the seed’s features, are more constantly, having a larger sistematic value, but they have been less used. It has been described a very large number of varieties and forms of plant species. In the lately Floras, often, the infraspecifically variability is stopped at the level of subspecies and, rarely, at varieties. In this paper, it has been analyzed the variability at 3 (three) plant species, namely: Silene supina Bieb., Alkanna tinctoria Tausch, and Himantoglossum hircinum (L.) Spreng.. The results are the next ones: 1. Silene supina Bieb. This species has been described, more or less unitary in all the Floras; only the calyx is depicted, within great differences, thus: - Schischkin (Flora of U. R. S. S., 1936): the calyx has a longer of 14-20 mm; - Klokov (Flora of Ukraine, 1952): the calyx has a longer of 17-24 mm; - Chater & Walters (Flora Europaea, 1964): the calyx has a longer of 17-20 mm; - Chater, Walters & Akeroyd (Flora Europaea, 1993): the calyx has a longer of 11-20 mm; - Jordanov & Panov (Flora of Bulgaria, 1966): the calyx has a longer of 12,5- 14,5 mm. In all the references sources, the capsule is more or less equally in length, having a pubescent carpophore. Our samples has been collected from Dealul Pietros – Agighiol, Tulcea county; the calyx is of 17-23 mm in length, the capsule is of 8-10 mm in length, equally in length with the carpophore, which is of 7-12 mm in length; it means that all of these data are alike with those ones from the reference material. ∗ Universitatea de Ştiinţe
