| Se describe Thamniopsis flexifolium, una nueva especie para las Yungas en el noroeste de la Argentina que se distingue de sus congéneres por las plantas rojizas a púrpuras, los dientes del margen foliar grandes y agudos, y las células de la lámina de paredes lateralmente engrosadas, a veces proradas. Se registra además un nuevo taxón para el país: Lepidopilum muelleri. Se incluyen descripciones, distribuciones, ilustraciones, comentarios de las novedades taxonómicas y una clave para las especies de la familia Pilotrichaceae del noroeste de Argentina. |

| In the present contribution, the sporophyte of Chenia lorentzii is described in detail and microphotographs are provided. In addition, the role of sporophytic characters is discussed in a phylogenetic context. To accomplish this task, first, a phylogenetic analysis of a reduced dataset of Pottiaceae genera was carried out by using molecular data (nad5, rps4, 26S) and combined data (morphology and molecular markers). Then, gametophytic and sporophytic characters were mapped onto the molecular tree and their fit to the phylogeny was assessed on the basis of their extra steps and the number of diagnosed nodes. Results suggest that sporophytic characters should be treated with caution when nomenclatural generic changes are proposed. |

| Philonotis pomangium is a neotropical species recorded from Argentina, Bolivia and Brazil. It is characterized by the ovate-lanceolate leaves, laminal cell quadrate at the base, papillose at the distal angles, and propagules present (brood branches). During the revision of the genus Philonotis in southern South America some samples collected in Peru agreed with P. pomangium, a species not recorded for the country. In addition, the study of the type specimens of Philonotis boliviensis was performed, and it is proposed as a new synonym of P. pomangium. A description, photomicrographs on OM and SEM, comments on the species, and a comparative table for related Philonotis species of Peru are here presented. The Neotropical distribution of P. pomangium is... |
