1 By T. Pócs, Eger and P. TIXIER, Paris

2 In the course of working up their SE Asian Syrrhopodon material, authors encountered a number of problems, since the widely ranging ciliferous species — excepting the well isolated S. ciliatus — of the genus so rich in species had been described in the different areas by one name after the other. The cause of this confusion may have been the fact that in the description of the new species the breadth and the length of the lamina was taken as the fundamental specific concept, a character extremely varying even within a given plant in the Syrrhopodon species. Authors found a more reliable and important feature in the type of the laminál papillae, and the situation of the cancellinae (endohyalocysts) of the leaf base. For their comparative studies, they used the material of the Laboratoire de Cryptogamie, Muséum Nat. d'Histoire Naturelle, Paris, for which they wish to express their thanks also in this place to Director Prof. ROGER HEIM. T. PÓCS received also a valuable comparative material from MAURICE BIZOT, Professor of Botany, Dijon, France, Dr. SINSKE HATTORI, Director of the HATTORI Botanical Laboratory, Nichinan, Japan, and Prof. ÁDÁM BOROS, Budapest. The senior author expresses his gratitude for their support and cordial aid. Syrrhopodon larminati PAR. & BROTH. Z. IWATSUKI (1965:219) showed the identity of Syrrhopodon philippinensis BARTRAM, and S. doii (SAK.) SAK., with the earlier Syrrhopodon tsushimae CARD., in the Section Cavifolii of the genus Syrrhopodon. Since T. Pócs and TRAN NINH collected in North Vietnam plants belonging to the Formenkreis of S. tsushimae. The authors compared them to the available S. tsushimae specimens, and to exemplars of Syrrhopodon larminati PAR. et BROTH., described from North Vietnam, and identified by E. G. PARIS. It was found that Syrrhopodon larminati PAR. & BROTH, is also synonymous with the preceding ones, and as the first available name it is the senior synonym, and has precedence over them. The only problem is that PARIS failed to define exactly in his paper (1901:125) the locality of origin of the type-specimen of S. larminati, hence we based our comparison on the specimen deriving also from LARMINAT'S collecting in 1904, and also identified by PARIS. The new synonyms of Syrrhopodon larminati PAR. & BROTH., Rev. Bryol. 28(1901): 125, are therefore S. tsushimae CARD., Bull. Herb. Boiss. 7(1907) :716; S. philippinensis BARTRAM, PHILIPP. Journ. Sei. 68(1939) :83; Trichostomum doii SAK., Bot. Mag. Tokyo 47(1933) :333; Syrrhopodon doii (SAK.) SAK., Muscologia Japonica (1954) :49. 1 The study was sponsored by the Centre National de la Recherche Scientifique (France). The material studied is deposited in the Laboratoire de Cryptogam ( , Muséum Nat. d'Histoire Naturelle, Paris, partly in the Botanical Department of the Hungarirn Natural History Museum, Budapest, in the Department of Botany of the Teachers' College, Eger, Hungary, and in the Department of Biology of the Scientific Council, Hanoi, Democratic Republic of Vietnam. 2 Dept. of Botany, Teachers' College, Eger, Hungary, and Laboratoire de Cryptogamie, Muséum National d'Histoire Naturelle, Paris, France.
