Mate (Ilex paraguariensis A. S. Hil.) is an economically important Brazilian native species. Mate genetic improvement programs have been established basically aiming biomass productivity and product quality. Controlled pollination allows to combine desirable characteristics for this species. Thus, adequate controlled pollination techniques must be made available. This work aimed to develop a methodology for controlled pollination in mate. For that purpose, a 15 years old clonal test was used at Embrapa Florestas-Colombo-PR with nine treatments applied on three flowering trees (replications). Flowers were pollinated in November 2010 and the fruits were collected in March 2011. Fruits and seeds produced were quantified and embryos viability was evaluated throughout tetrazolium test. Data analysis was made based on the GLM procedure of the R program. Higher production of fruits and seeds was showed in controlled pollination when compared to open pollination. It can be concluded that controlled pollination after the anthesis of this species must be lead in two consecutive days to ensure a good seed production for mate. © 2015, Sociedade de Investigacoes Florestais.

Piper delirioi Sarnaglia & E. F. Guim. (Piperaceae), is a new species from southeastern Brazil (Espírito Santo State) proximately related to P. aduncum and P. gaudichaudianum. Although considered a taxonomic novelty, it is already regarded as endangered by the IUCN standards, due to its limited distribution area of about 250 km². We present complete description, taxonomic and geographic notes, and illustrations. © 2015 Magnolia Press.
