| In tropical forests, tree ferns constitute an important phorophyte for the establishment and occurrence of epiphytic species. Composition, structure and vertical distribution of epiphytic ferns were studied on Alsophila setosa Kaulf., in a semideciduous seasonal forest fragment, in the city of Morro Reuter (29º32'07"S and 51º05'26"W), in the state of Rio Grande do Sul, Brazil. The sample consisted of 60 caudices of at least 4 m high, which were divided in 1 m intervals from the ground. The specific importance value was estimated trough the coverage value and caudex frequency at the intervals. A total of 14 species was recorded, belonging to 10 genera and five families. The highest specific richness occurred in Polypodiaceae. The rarefaction curve for the... |

| Cystoseira baccata, a biological quality element for the implementation of the Water Framework and Marine Strategy EU Directives, is a dominant species in the subtidal rocky bottoms of the Basque coast. As part of this issue and given the need to better understand the functional character of benthic rocky ecosystems and use them as a reference to anthropogenic changes, two samplings campaigns were conducted in 2014 and 2017. Several population parameters (i.e. frond density, frond length frond-length/total frond-length ratio and taxonomic richness of epibionts) of C. baccata were studied from three sites monitored within the Water Directive Framework in relation to bathymetry during the two campaigns. The results showed a significant influence of... |

| One hundred and thirty eight epiphytic lichen species in 40 genera, are recorded from Conguillio National Park (38°30'-38°50' S; 71°30'-71°55' W), with predominancy of typically southern South American species. Lichen diversity is high, about 9 % of the lichen mycobiota from Chile, due mainly to species of the genera Bunodophoron, Menegazzia, Nephroma,, Pannaria, Protousnea and Pseudocyphellaria. Levels of endemism are rather high (nearly 40 %); also austral and cosmopolitan species, about 19 % and 16 % respectively, are the most representative biogeographical elements in the Park. |

| Se describen las estructuras reproductivas en Avrainvillea elliottii A. Gepp et E. S. Gepp, A. longicaulis f. laxa D. S. Littler et M. M. Littler y A. digitata Littler et Littler para aguas cubanas. Se revisaron materiales de herbario del género Avrainvillea, así como ejemplares de reciente colecta y se registraron un total de 41 táxones, 23 Rhodopyta, 4 Ochrophyta y 14 Chlorophyta como epífitas. A. levis Howe presentó como epífitas a miembros de su misma especie, tanto en la lámina como en la porción apical del estipe. Los rizoides pegados a los talos epifitos de A. levis tiene forma de disco. El estipe fue la región del talo que presentó el mayor número de especies epífitas. Se adicionan siete especies de algas marinas a la flora ficológica de Cuba:... |

| The taxonomy and ecology of the genus Hoya R.Br, are unclear, especially in the core area of its distribution: Sumatra, Borneo, Sulawesi and Irian Jaya. This paper summarises the available information on the ecology of Hoya species, and describes eight species from central Sulawesi. An important ecological trait of many Hoya species is their association with ants. Four types of mutualistic relationships with ants occur in the genus: 1) species with specialised leaves to house ants; 2) a single species that provides housing for ants under imbricate leaves; 3) species growing on the carton of ant nests; and 4) species that root in ant inhabited cavities in tree trunks and branches. Four of the eight described species grew in association with ants (types... |

| ABSTRACTThe genus Sinningia belongs to the Neotropical tribe Gesnerieae, subtribe Ligeriinae, presently consisting of only three genera, Paliavana, Sinnigiaand Vanhouttea. These genera were separated from a larger concept of tribe Gloxinieae based on phylogenetic studies with molecular data. In Rio Grande do Sul, southern Brazil, 12 species and one natural hybrid of Sinningiahave been recorded. Species of Sinningia in this area are erect or ascending herbs or subshrubs arising from underground or partially exposed tubers. They grow in very distinct ecological conditions, from water-saturated marshes to dry grasslands or shrublands, but most often in rupicolous or epiphytic habitats commonly associated with forest environments. In this review we provide an... |

| Pollen grain morphology of Bromeliaceae species collected in areas of the Atlantic Rainforest of southeastern Brazil was studied. The following species were analyzed: Aechmea bambusoides L.B.Sm. & Reitz, A. nudicaulis (L.) Griseb., A. ramosa Mart. ex Schult.f., Ananas bracteatus (Lindl.) Schult.f., Billbergia distachia (Vell.)
