Fenestratarum is described as a new genus of Tribe Schismatoglottideae, with a single novel species, Fenestratarum culum. Preliminary molecular analyses places Fenestratarum near the base of a clade comprised of Bakoa, Hottarum, two clades containing species currently assigned to Aridarum, and a clade of species presently included in Piptospatha.

A new species of Araceae, Rhodospatha arborescens, was found in two preservation areas in Minas Gerais state, Brazil, Caratinga Biological Station and Rio Doce State Park, both located in a semideciduous seasonal forest (Interior Atlantic Rainforest). The new species is helophytic and arborescent. It is described, illustrated, and compared with Rhodospatha species that occur in the Atlantic Rainforest, using a dichotomous key. Information is also presented on the geographic distribution, ecology, and phenology these species.

None of the 17 recorded genera are endemic, and one (Colocasia) is non-indigenous. Two species occur as adventives (Alocasia macrorrhizos and Amorphophallus paeoniifolius), and one (Colocasia esculenta) occurs semi-naturalized as an escape from cultivation as a carbohydrate crop. A preliminary checklist of the Araceae of Sulawesi is offered, and keys to the genera, and to the Sulawesi species of Schismatoglottis and Homalomena, are presented.

A collection made in 1872 by Johannes Elias Teijsmann (J.E. Teijsmann 16705) on Pulau Lingga (Kepulauan Riau Province, Lingga Regency, Indonesia) has long been Piptospatha. Recent living collections have now shown that this collection is a taxonomic novelty, endemic to the Lingga Archipelago, and here described as Piptospatha teijsmannii. Piptospatha teijsmannii is morphologically most similar to Piptospatha ridleyi N.E.Br ex Hook.f., a species restricted to the Peninsular Malaysian states of Johor and Pahang, differing by the morphology of its flowers. Both P. teijsmannii and P. ridleyi are illustrated in colour, and differentiated with an identification key to the species of Piptospatha in Peninsular Malaysia and Lingga Regency. Speculation as to the possible evolutionary origin of P. teijsmannii is proffered.

The genus Bognera Mayo \& Nicolson with its single species Bognera recondita (Madison) Mayo \& Nicolson, is described and illustrated and its relationships are discussed in detail. Discussions of its history, discovery, distribution, ecology, pollination, etymology and cultivation are given. The genus Bognera is characterized by its creeping rhizome shoot architecture with two cataphylls preceding each foliage leaf, the last one partly enveloping the petiole (a character unique in the family), the essentially parallel-pinnate venation type (philodendroid) but with third order veins in a clearly reticulate pattern, the unconstricted spathe, the stamens of each male flower connate into a synandrium, the female flowers lacking staminodes, the unilocular ovary with a single anatropous ovule on a basal placenta and the inaperturate pollen grains with smooth (psilate) exine.

Summary. A comparative study of the leaf outline morphometrics of Monstera adansonii var. klotzschiana, M. adansonii var. laniata and M. praetermissa was carried out. The study focused on populations in isolated montane humid (brejo) forests of Cear\á state in Northeast Brazil and compared them with populations from Amazonia and the Brazilian Atlantic Forest. Digitised outlines were prepared from a total of 1,695 field-collected leaf images from 20 populations, and elliptic Fourier analysis was used to generate matrices of coefficients, from which six shape variables (principal components) were extracted using Principal Components Analysis. Intra-population variability and inter-population differences were analysed with multivariate distance methods. Separate analyses were carried out for each of three leaf size classes (juvenile, submature, mature) because of the strong heteroblasty typical of this genus. Juvenile leaves were the least variable size class within populations of M. adansonii var. klotzschiana. The shape variables expressed very similar types of variation in all three size classes. The Cear\á brejo populations of M. adansonii var. klotzschiana showed significant differences between mature leaf outlines in all pairwise comparisons; the Pacatuba population was the most distinct. The Cear\á populations did not cluster together exclusively. In all three size classes, populations clustered together into their taxonomic groups, most clearly so in mature leaves. No correlation between morphological and geographic distance matrices was found, nor between morphological and molecular distance. The study showed that leaf outline shape is a practicable and useful quantitative trait for studying morphological variability at species, varietal and population levels.
