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&ndash;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.</p>

Considering the small size of previously included genera in the tribe (10 geophytic genera, none with more than 15 described species), generic circumscription has been considered troublesome. To address these issues, we sequenced two cpDNA markers (matK and trnL-F) and reconstructed the phylogeny of the tribe using two approaches: Maximum parsimony and Bayesian Inference. We also evaluated the eVect of adding phenotypic characters in a “total evidence” analysis. Our results conWrm the previous suggestion that the two non-geophytic genera Dieffenbachia and Bognera should be included in Spathicarpeae, but the precise placement of Bognera within the tribe is still unresolved. Our results also support the segregation of Asterostigma pavonii and Asterostigma integrifolium, recently described as new monospeciWc genera (Incarum and Croatiella, respectively). The reconstructed phylogenies suggest that the invasion of the Andean range by the Spathicarpeae occurred in at least two independent events. The inclusion of phenotypic characters in a combined analysis has improved both internal resolution and the number of strongly supported clades.10aAraceae10aBayesian inference10aBognera10aCombined data10aDieffenbachia10amatK10aSpathicarpeae10aTotal evidence10atrnL-F1 ac}alves, E., G.
