Abstract\—Previous studies have shown Homalomena as traditionally defined to be polyphyletic, with Neotropical species phylogenetically distinct from Asian species. This study of 29 accessions of 10 Neotropical taxa, and a total of 135 accessions representing 92 taxa of Homalomena, Furtadoa, and Philodendron for nuclear ITS and plastid matK regions, supports resurrection of the genus Adelonema for Neotropical species currently assigned to Homalomena. Adelonema is here delimited as a Neotropical genus of 16 species divided into two new sections: sect. Adelonema and sect. Curmeria, based on morphologically supported molecular results. The genus Adelonema is distinguished by a hypogeal rhizome, crushed vegetative tissues smelling of anise, an extensively sheathing, sometimes prickly petiole, chartaceous often variegated leaf blades, a spadix either obliquely inserted on the spathe/peduncle (sect. Adelonema), or stipitate (sect. Curmeria), ovaries with 2\–4-pluriovulate locules, and anatropous ovules on an axile placenta. Four new species are described: Adelonema orientalis, A. palidinervia, A. panamensis, and A. yanamonoensis. Eleven new combinations are made: Adelonema allenii, A. crinipes, A. hammelii, A. kvistii, A. moffleriana, A. peltata, A. picturata, A. roezlii, A. speariae, A. wallisii, and A. wendlandii.

The genus Philodendron (Araceae) is a large neotropical group whose classification remains unclear. Previous classifications are based on morphological characters, mainly from the inflorescence, flower and leaf shape. The classification by Krause, with few modifications, is still the most commonly used system. To examine phylogenetic relationships in the genus, two ribosomal DNA nuclear markers, internal transcribed spacer (ITS) and external transcribed spacer (ETS), and the chloroplast intron rpl16, were sequenced and analysed for more than 80 species of Philodendron and its close relative Homalomena. According to the resulting phylogeny, the genus Homalomena may be paraphyletic to the genus Philodendron. The inclusion of the American Homalomena species within the genus Philodendron might resolve this taxonomic problem. All three subgenera of Philodendron were revealed as monophyletic. Below the subgeneric level, the groups obtained in our phylogeny globally correspond to sections recognized in previous classifications. Among the morphological characters used by previous taxonomists to build their classifications, and which we optimized onto one of the most parsimonious trees, most characters were found to be homoplasious. However, leaf shape, characteristics of the sterile zone on the spadix and venation patterns are useful for delimiting subgenera and sections within the genus.

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.
