Monstera alcirana, endemic to Panamá, is described and illustrated using a color plate based on photographs of the vegetative and reproductive structures of living material. This species is the fourth of the very small species of Monstera in Central America. It is morphologically similar to M. obliqua, M. minima and M. gambensis but differs by has short internodes, thickly coriaceous blade and peduncle longer than the length of the leaf.

A New Species

Species of genus Monstera are among the most representative hemi-epiphytic Araceae in the Neotropics. They are widely distributed and abundant in the tropical forests of Costa Rica and Panama. During recent exploration in the border region between the two countries, an undescribed species belonging to the genus has been identified. The new species, Mostera limitaris, is described and illustrated here, using a color plate based on photographs of the vegetative and reproductive structures of live material.

Living Material

The genus Monstera is represented in Colombia by 20 species, 12 of them from the Pacific slope of the Andes. Fieldwork between 2017 and 2019 in this region and a thorough revision of the main Colombian herbaria allowed us to discover two undescribed species belonging to Monstera section Monstera. The two new species are described and illustrated using color photographs of vegetative and reproductive features from living material, and compared to Monstera oreophila, M. epipremnoides and M. dissecta from Central America.

The genus Dendropsophus Fitzinger, 1843 currently includes 92 species of hylid treefrogs distributed from South and Central America to southern Mexico (Frost 2011). Dendropsophus haddadi is a small species of this genus (male SVL 15–19 mm; female SVL 21–24 mm) that is allocated in the D. decipiens clade, part of the D. microcephalus group, together with other three species: D. berthalutzae, D. decipiens, and D. oliveirai (Faivovich et al. 2005; Frost 2011). This species was recorded in regions of ombrophilous Atlantic forest and scrubby restinga vegetation mainly in coastal areas between the state of Espírito Santo and Pernambuco, Brazil (Bastos & Pombal 1996; Amorim et al. 2009; Camurugi et al. 2010; Araújo-Neto et al. 2012), ranging from sea level up to 650 m of elevation (Peixoto & Pimenta 2004). In this paper, we described the tadpole of D. haddadi from a population from southern Bahia, northeastern Brazil.

A New Species

Anthurium Schott (1829: 828) is a monophyletic and neotropical genus, which is present from Mexico to Argentina (Croat 1986, Carlsen & Croat 2013). The genus is estimated by ca. 1500 species in the Neotropics (Boyce & Croat 2012), including 250 that are present in Central America, where the greatest diversity is found in Panama and Costa Rica (Croat 1986). In the Revision of Anthurium for Panama (Croat 1986), 16 sections are recognized. Croat et al. (2005) described a new section of the genus, called Decurrentia Croat (2005: 14), which includes A. decurrens Poeppig & Endlicher (1845: 83) and A. pittieri Engler (1898: 372). The latter species are present in Panama and Costa Rica (Croat 1986) and were previously classified within Section Oxycarpium Schott (1860: 450) based on the work of Schott (1860) and Engler (1905). The Decurrentia section is mainly characterized by short internodes, elongate petioles and epunctate leaf blades with an acute base. There are currently 46 species in section Decurrentia but some of the species are as yet unpublished.

The advantages of freeze substitution fixation over conventional chemical fixation for preservation of ultrastructural details in fungi have been discussed by various authors. As most ascomycetes, basidiomycetes and deuteromycetes do not fix well using conventional chemical fixation protocols, freeze substitution has attracted the attention of many individuals interested in fungal ultrastructure. Thus far most workers using this technique on fungi have concentrated on thin walled somatic hyphae. However, in our laboratory we have experimented with the use of freeze substitution on a variety of fungal reproductive structures and spores with promising results.Here we present data on freeze substituted samples of sporangia of the zygomycete Umbellopsis vinacea, basidia of Exobasidium camelliae var. gracilis, developing teliospores of the smut Sporisorium sorghi, germinating teliospores of the rust Gymnosporangium clavipes, germinating conidia of the deuteromycete Cercosporidium personatum, and developing ascospores of Ascodesmis nigricans.Spores of G. clavipes and C. personatum were deposited on moist pieces of sterile dialysis membrane where they hydrated and germinated. Asci of A. nigricans developed on pieces of dialysis membrane lying on nutrient agar plates. U. vinacea was cultured on small pieces of agar-coated wire. In the plant pathogens E. camelliae var. gracilis and S. sorghi, a razor blade was used to remove smal1 pieces of infected host issue. All samples were plunged directly into liquid propane and processed for study according to Hoch.l Samples on dialysis membrane were flat embedded. Serial thin sections were cut using a diamond knife, collected on slot grids, and allowed to dry down onto Formvar coated aluminum racks. Sections were post stained with uranyl acetate and lead citrate.
