Abstract\—A phylogenetic analysis of the genus Homalomena (Araceae: Homalomeneae) based on the nITS region is presented. Eighty-nine taxa are included; representing all Asian supergroups, several Neotropical species currently assigned to Homalomena, and selected species of Philodendron. Asian Homalomena is well supported as monophyletic and excludes Neotropical Homalomena. The Cyrtocladon supergroup is monophyletic after transferring the Insignis complex and Havilandii complex into the Punctulata supergroup. The Homalomena and Chamaecladon supergroups are well supported. A reduced phylogeny of 20 accessions representing 15 taxa was used for subsequent morphological and chemical marker optimization. A constricted spathe and four stamens per staminate flower are plesiomorphic for Homalomena. Staminodes among the pistillate zone are lost three times independently in Homalomena supergroup, Punctulata supergroup, and H. vivens. Chemical markers identified from liquid chromatography-mass spectroscopy profiling provided an independent set of markers that further support the separation of Neotropical species of Homalomena from the Asian taxon. Three chemical markers at Rt 2.55 min, 2.69 min, and 2.90 min are shared among the majority of taxa sampled for Asian Homalomena, and Neotropical species currently assigned to Homalomena show two unique peaks at Rt 3.25 min and 3.54 min. Five chemical markers support the Cyrtocladon supergroup with the exception of Homalomena vivens. A chemical marker at Rt 3.60 min is plesiomorphic for the Chamaecladon, Homalomena and Punctulata supergroups. A chemical marker at Rt 2.80 min is apomorphic for the Chamaecladon supergroup, with a separate gain in H. punctulata. This study supports removal of the Neotropical species from Homalomena, redefines the morphological boundaries of Homalomena sensu stricto (i.e. the Asian species), and supports and refines the grouping of Asian species into supergroups.

Abstract Tribe Schismatoglottideae comprises one large genus, Schismatoglottis, and six small \‘satellite\’ genera. A combined molecular phylogenetic analysis of matK, the 3\′ portion of the trnK intron, and trnL-F sequence data was carried out on 77 taxa representing all genera in the tribe, all informal groups in Schismatoglottis, together with sister tribe Cryptocoryneae, and outgroups from Araceae. Analyses of combined datasets with parsimony, maximum likelihood, and Bayesian methods revealed tribe Schismatoglottideae to be a polyphyletic assemblage. Neotropical Schismatoglottis is shown to be sister to the palaeotropical Schismatoglottideae + Cryptocoryneae. Schismatoglottis acuminatissima is a sister clade to the rest of the Schismatoglottideae. Palaeotropical Schismatoglottis is unsupported as a monophyletic genus. A new neotropical tribe of Araceae, Philonotieae S.Y.\ Wong \& P.C. Boyce, sister to Cryptocoryneae + palaeotropical Schismatoglottideae, is proposed.

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.

Abstract. The genus Philodendron Schott comprises the following three currently accepted subgenenera: P. subg. Philodendron, P. subg. Pteromischum and P. subg. Meconostigma; however, these lack a well-defined classification. In the present study, we examined anatomically samples of adventitious roots in species of the group, so as to establish aspects relevant for taxonomic purposes. The anatomical analyses emphasised the characteristics of the steles in cross-sections of the root samples from regions near the apex to the most mature zones. A species of a closely related genus Adelonema, namely A. crinipes, was included in the study to clarify the results. Our results indicated notable differences in the species of the subgenus Meconostigma, mainly in terms of the presence (and variations) of a lobed stele, whereas the cylindrical stele stood out among the common characteristics in P. subg. Philodendron, P. subg. Pteromischum and the related species A. crinipes. Moreover, the characteristics shared by P. subg. Philodendron and P. subg. Pteromischum corroborated the phylogenetic hypothesis that these two taxa were more closely related to one another than to P. subg. Meconostigma.

Two taxonomically novel Aridarum species, A. kazuyae and A. orientale, are described from Kalimantan Timur, Indonesian Borneo. They are most similar to A. burttii from Sarawak, and together with A. minimum from Kalimantan Barat represent a morphotaxon, here called the Burttii Complex, defined by staminate flowers comprised of one stamen with an obliquely excavated expanded connective, hemispherical interstice staminodes, a spathe limb deliquescing acroscopically from its junction with the lower persistent portion and leaf blades with adaxially prominently raised primary lateral veins. Recognition of the new species proposed here takes the genus Aridarum to 12 accepted species.

Recent studies on Schismatoglottideae have resulted in the recognition of four new monophyletic genera, the resurrection of two additional genera following clarification of their monophyly, and the publication of many taxonomically novel species. However, generic boundaries among some parts of Schismatoglottideae remain unclear owing to several reasons: (1) more taxa are being revealed through our on-going fieldwork, now expanded to previously unsampled localities on Borneo; (2) established occurrence of a high level of homoplasies among the morphological characteristics hitherto used to delimitate genera; and (3) gene regions used in previous studies contradicted some of current taxonomic placements. Among the unsolved groups from previous studies a clade comprising Schismatoglottis sarikeensis and S. josefii needs further investigation. Therefore, phylogenetic analyses were carried out to investigate the position of these two species using the nuclear region, internal transcribed spacer and combined plastid regions: trnL intron and trnLF intergenic spacer, coding matK?partial 30 trnK, intergenic spacer trnH-psbA. A total of 23 accessions representing 16 taxa of Schismatoglottideae and Philonotieae were included in the study. Phylogenetic analyses of a total 4,658 bp combined dataset using parsimony, maximum likelihood, and Bayesian methods revealed that S. sarikeensis and S. josefii do not belong to Schismatoglottis, and therefore are transferred to Schottarum (:Hottarum sarikeense: Schismatoglottis sarikeense). Flowering mechanism, pollination strategy, and fruitset of S. sarikeense are also presented in the paper.

C.\ Boyce, sp. nov. Furthermore, three pre-existing species names are transferred from Microcasia Becc. to Bucephalandra: B. elliptica (Engl.) S. Y. Wong \& P. C.\ Boyce, comb. nov. (\≡ Microcasia elliptica Engl.), B. muluensis (M. Hotta) S. Y. Wong \& P. C.\ Boyce, comb. nov. (\≡ M. muluensis M. Hotta) and B. oblanceolata (M. Hotta) S. Y. Wong \& P. C.\ Boyce, comb. nov. (\≡ M. oblanceolata M. Hotta). Together these changes take Bucephalandra to 27 species. An updated generic description is provided, and a key to all species is offered. All species dealt with taxonomically and nomenclaturally are illustrated from living plants, and with comparative plates of the spadices. Where possible scientific names are correlated to nomenclature used by commercial suppliers. Remaining taxonomic problems are highlighted, and foci for further study suggested. Notes on the role of the motile interstice staminodes are supplied.

Subsection Rupicola, a new subsection of Anthurium section Calomystrium is proposed, encompassing nine rupicolous species. Descriptions and a key are provided for these species including: A. antrophyoides Killip, from Ecuador and Colombia, A. chocoense Croat and A. antioquiense Engler from Colombia, as well as A. amnicola Dressler, and A. sytsmae Croat from Panama. Five species, A. palacioanum Croat and A. werffii Croat from Ecuador, and A. chocoense Croat, A. callejasii Croat, and A. vanderknaapii Croat, from Colombia, are described as new. Members of this group were previously thought to belong in section Porphyrochitonium because of their generally lanceolate leaf blades, and stems with short internodes. However, lack of distinct glandular punctations on blade surfaces and the ability to interbreed readily with other members of section Calomystrium indicate that this new group belongs in section Calomystrium, and has evolved without conspicuous posterior lobes typical of section Calomystrium, owing to their rupicolous habitat.

A new Gorgonidium species from Bolivia, G. beckianum, is described and illustrated. It is characterized by its globular ovary, a subsessile, discoid stigma and shorter, slightly clavate and slender staminodes of the female flowers. G. beckianum is closely related to G. vermicidum and G. striatum, which mainly differ by an ovoid ovary, a distinct style and a star-like or subhemispheric stigma as well as by the shape of their staminodes.
