Segregation of Leptatherum from Microstegium (Andropogoneae, Poaceae) confirmed by Internal Transcribed Spacer DNA sequences Naturalis
Chen, C.-H.; Veldkamp, J.F.; Kuoh, C.-S.; Tsai, C.-C.; Chiang, Y.-C..
Phylogenetic analyses of Microstegium (Andropogoneae, Poaceae) and some other Andropogoneae species were conducted inferred from the ITS/5.8S sequences. As a result of this study, Microstegium is polyphyletic. There are two rather distant monophyletic clades, one with Microstegium nudum (type of Leptatherum), M. japonicum and M. somae, the other one with M. ciliatum, M. fauriei, M. geniculatum and M. vimineum (type of Microstegium). Therefore we feel justified to reinstate the genus Leptatherum and three new combinations, Leptatherum boreale, L. nudum and L. somae, are proposed.

On the morphology and molecular basis of segregation of Ceriops zippeliana and C. decandra (Rhizophoraceae) from Asia Naturalis
Sheue, C.-R.; Liu, H.-Y.; Tsai, C.-C.; Rashid, S.M.A.; Yong, J.W.H.; Yang, Y.-P..
Ceriops zippeliana, a member of the mangrove Rhizophoraceae, was first reported in 1849. It was considered to be a synonym of C. decandra, which is still widely accepted. We present morphological and molecular evidence to show that C. zippeliana is significantly distinct from C. decandra, and illustrations and an identification key to both species.
Tipo: Article / Letter to the editor Palavras-chave: Ceriops decandra; Ceriops zippeliana; Lectotypification; Malesia; Mangrove; Rhizophoraceae; TrnL intron.
