The Hornwort and Liverwort Atlas of Romania

The beginning of the 20 th century is dominated by the Romanian bryologist Simeon ŞtefanRadian, who describes the genus Bucegia, with the species B. romanica, from the Cerbului Valley in theBucegi Mountains, the species being confirmed by Schiffner V. in 1903 and Müller K. in 1906. Becauseof the author’s special flair, the correctitude with which he described this species and because of the factthat it was included in the work of reference entitled “Die Lebermoose Deutschland, Österreich u. d.Schweiz mit Berücksichtigung der übrigen Länder Europas” (Müller 1906-1911), Bucegia romanicaRadian remained untouched by the later attempts of some bryologists for renaming the species (asRadiania rumaenica or Bucsecsia).After obtaining his diploma in natural sciences in 1894, Radian immediately started his bryologicalstudies in the Bucegi Mountains. In 1901 he published two synthesis works for that period regarding thebryophytes from Romania (Radian 1901a, Radian 1901b), together with a list of mosses collected byPopovici A. Bâznoşanu from Stânca-Ştefăneşti, Botoşani county (Procopianu-Popovici 1901:27, annex).In 1903, he described the species Bucegia romanica in the paper entitled “Sur le Bucegia nouveau genred'Hépatiques a Thalle”. In 1915 and 1920 the contributions III and IV to the Romanian liverwort florawere published, where liverwort species are cited for the first time, some of them confirmed by us after89 years since the first publication (Asterella gracilis), some still unfound (Riccia warnstorfii). In 1922 hepresented the work entitled “Anatomia aparatului vegetativ de la Bucegia romanica Radian” (Theanatomy of the vegetative apparatus of Bucegia romanica Radian) in order to obtain the doctoral title, thisbeing the first doctoral thesis in the domain of bryology in Romania (Radian 1923).The first half of the 20 th century is marked by the apparition of several important bryologicalpublications. In this period the following authors have published: Degen A. (1901), Röll J. (1902, 1903),Matouschek F. (1903, 1905), Péterfi M. (1901-1904, 1906, 1908-1910, 1918), Györffy I. (1903-1912,1914-1917), Barth J. (1905), Wolcsánszky J. (1905), Grinţescu G.P. (1907), Prodan I. (1907), SchiffnerV. (1908), Pax F. (1908), Gusztáv M. (1910), Lilienfeldówna F. (1911), Szurák J. (1912), etc.Another Romanian researcher who activated in the field of bryology for 48 years (1924-1972) andwho published in this domain about 90 scientific papers in and outside the country was Constantin Papp.Born on the 1 st of January 1896, Papp C. has studied at the Faculty of Sciences (botany) of the “Al.I. Cuza” University and also at the Faculty of Medicine (pharmacy), obtaining his diploma certificate bothin natural sciences (1921) and in pharmacy (1922). In 1926 he defended his doctoral thesis “Contribuţiunila studiul briofitelor din Moldova” (Contributions to the study of bryophytes in Moldova), that representsthe second doctoral thesis in bryology from Romania.Most of his publications in bryology are referring to different regions from Moldova (56 titles), buthe has also conducted research in Dobrogea, Bucovina, Transylvania, Banat etc.He studied the bryoflora of the Ceahlău, Rarău, Bucegi and Leaota Mountains, from Cheile Turzii,Cheile Mari ale Bicazului and from Cumpătul.A special merit of prof. Papp C. in the field of bryology is represented by the publication of thefirst guide for cryptogams, “Plante vasculare cuprinzând şi chei dichotomice pentru determinarea până lagenuri a briofitelor din împrejurimile oraşului Iaşi” (Vacular plants, containing also dichotomous keys forthe determination till the genus of the bryophytes from the surroundings of the city of Iaşi) (Papp &Răvăruţ 1938), “Flora pentru determinarea briofitelor cunoscute în Moldova dintre Carpaţi şi Prut” (Florafor the determination of bryophytes known in Moldova, between the Carpathians and the Prut River)(Papp 1943), “Briofitele din Republica Socialistă România (determinator)” (The bryophytes from theRomanian Socialist Republic - guide) (Papp 1967a) (Mititelu & Barabaş V. 1971:913).Papp C. collaborated at the editing of the Exssicatae and the Schedae from Romania (Cluj, Iaşi,Constanţa, Bacău), he determined and verified the bryological materials from geobotanical works. Heorganized the Botanical Department of the University in Iaşi, a collection with a rich bryological material(Ştefureac 1973a:467-472; Ştefureac 1973e:664-667).The most prolific Romanian researcher in the domain of bryology was Traian I. Ştefureac, who in1940 defended his doctoral thesis entitled “Cercetări sinecologice şi sociologice asupra bryophytelor dinCodrul Secular Slătioara (Bucovina)” (Sinecological and sociological studies on the bryophytes from theSlătioara Ancient Forest (Bucovina) (Ştefureac 1941), the first doctoral thesis in the field of bryophytecenology from Romania (Plămadă 1987a:335-337).During his 52 years of activity he published over 110 papers in the field of bryology in thespecialty journals from Romania and outside the country. Between his published works there are severalsynthesis works with monographic character, such as: “Studii briologice în unele formaţiuni de vegetaţie10
