TL;DR: Both molecular (ITS1) and morphological data support the recognition of an additional clade, Ehretia III (E. longiflora species group), characterised by four endocarpids, but differ in the presence of distinct lamellae on the abaxial surface of eachEndocarpid.
Abstract: Ehretia (Ehretiaceae, Boraginales) has been divided into two major clades, characterised by fruits with four endocarpids (Ehretia I, including species of Ehretia formerly belonging to Rotula) and by fruits with two endocarpids (Ehretia II, plus E. microphylla (= Carmona retusa) with an undivided endocarp), respectively. Both molecular (ITS1) and morphological data support the recognition of an additional clade, Ehretia III (E. longiflora species group). Its representatives are characterised by four endocarpids (as in Ehretia I), but differ in the presence of distinct lamellae on the abaxial surface of each endocarpid (as in Bourreria, also belonging to Ehretiaceae). However, molecular data suggest a close relationship with Ehretia II. At least three species belong to Ehretia III: Chinese E. longiflora, eastern Indian E. wallichiana, and Indonesian E. javanica.

TL;DR: The papillose, multicellular floral trichomes, the tepal’s erose margins, the small, zygomorphic perianth mouth and the dull purplish brown coloration give A. foertheriana a distinctive appearance within the genus.
Abstract: Afrothismia foertheriana, a new species of Burmanniaceae (tribe: Thismieae) from the peripheral zone of the Onge Forest Reserve in Cameroon’s Southwest Province is described and illustrated. The papillose, multicellular floral trichomes, the tepal’s erose margins, the small, zygomorphic perianth mouth and the dull purplish brown coloration give A. foertheriana a distinctive appearance within the genus. The species is here assessed as being critically endangered.

TL;DR: The genus Ochrosia Juss.
Abstract: The genus Ochrosia Juss. is revised in the Malesian region. Thirteen species are recognized as Ochrosia, including one new species, O. basistamina. Seven species previously placed in Neisosperma Raf. are now included in Ochrosia. The names Ochrosia section Echinocaryon F. Muell. and Ochrosia section Ochrosia are applied for the fibrous-fruited species and cavity-fruited species of Ochrosia, respectively. Neisosperma Raf. is reduced to Ochrosia section Echinocaryon F. Muell. Separate keys are given for the species of both sections.

TL;DR: Pimelodendron comprises five species, while P. naumannianum is regarded as a synonym of P. amboinicum, and one Sumatran species is to separate in the rest of Pimeloda without naming it.
Abstract: Pimelodendron comprises five species. Four species were already known (P. amboinicum, P. griffithianum, P. macrocarpum, P. zoanthogyne). One Sumatran species is to separate in the rest of Pimelodendron without naming it (Pimelodendron spec. nov.?). One name is excluded (P. dispersum = Actephila excelsa var. javanica), while P. naumannianum is regarded as a synonym of P. amboinicum.

TL;DR: A taxonomic revision of Amaracarpus Blume (Rubiaceae, Psychotrieae) is presented, with particular attention to the differences between AmaracARPus, Dolianthus and Psychotria.
Abstract: A taxonomic revision of Amaracarpus Blume (Rubiaceae, Psychotrieae) is presented. The salient characteristics of Amaracarpus are given, with particular attention to the differences between Amaracarpus, Dolianthus and Psychotria. The taxonomic account includes a key to species, an informal (artificial) subgeneric classification, full descriptions, and a list of specimens examined. Amaracarpus comprises 22 species: six new combinations are proposed, one new species is described, eight species are moved to other genera, the transfer of 12 species to Psychotria is confirmed, and numerous taxa are placed into synonymy. A checklist of all Amaracarpus names is provided.

TL;DR: Annesijoa is an endemic monotypic genus from New Guinea with as single species A. novoguineensis, and Elateriospermum is also monotypesic and found in West Malesia.
Abstract: Annesijoa is an endemic monotypic genus from New Guinea with as single species A. novoguineensis. Elateriospermum is also monotypic (E. tapos) and found in West Malesia. The South American genus Hevea comprises about 10 species. One species (H. brasiliensis) is presently cultivated worldwide in plantations for its rubber and has become one of the major economic products of SE Asia. Two other species, H. guianensis and H. pauciflora are sometimes present in Malesian botanical gardens.

TL;DR: The new orchid genus Devog Amelia from the Moluccas and New Guinea is described and its possible affinities are discussed and it is tentatively concluded that Devogelia belongs either to the tribe Cymbidieae or to the Malaxideae.
Abstract: The new orchid genus Devogelia from the Moluccas and New Guinea is described and illustrated. Its possible affinities are discussed and it is tentatively concluded that Devogelia belongs either to the tribe Cymbidieae or to the Malaxideae. So far a single species, here described as D. intonsa Schuit., is known, which occurs as a locally abundant terrestrial in lower montane forest.
TL;DR: The genus Solena Lour is redefined, and its 3 species and 1 subspecies are keyed out and described, and Solena amplexicaulis is taxonomically more distinct from the other two species of Solena.
Abstract: The genus Solena Lour. is redefined, and its 3 species and 1 subspecies are keyed out and described: S. amplexicaulis occurs in S India, S. heterophylla, with 2 subspecies is widespread, but does not occur in S India, and S. umbellata (Klein ex Willd.) W.J. de Wilde & Duyfjes, comb. nov., occurs in S India and Sri Lanka. The status of S. heterophylla subsp. napaulensis (Ser.) W.J. de Wilde & Duyfjes, comb. & stat. nov. needs further study as this subspecies is very similar to the more widespread subsp. heterophylla, but it is distinct by sigmoid thecae. Solena amplexicaulis is taxonomically more distinct from the other two species of Solena. In southern India Kedrostis foetidissima much resembles Solena in general habit, especially by the more or less amplexicaul leaves, and therefore it is discussed and keyed out against Solena.
TL;DR: Three new species of the Southeast Asian orchid genus Dendrochilum Blume are described and all seem to belong to the phenetically defined subgenus Platyclinis (Benth.) Pfitzer.
Abstract: Three new species of the Southeast Asian orchid genus Dendrochilum Blume are described. All three seem to belong to the phenetically defined subgenus Platyclinis (Benth.) Pfitzer. As indicated by the name, D. celebesense H.A. Pedersen & Gravend. originates from Sulawesi. The geographic origins of D. coccineum H.A. Pedersen & Gravend. and D. warrenii H.A. Pedersen & Gravend., on the other hand, are unknown, but parsimony analyses of sequences of the plastid accD-psaI intergenic spacer and nuclear ribosomal ITS1-5.8S-ITS2 region and morphological affinities suggest they should both be counted as members of the Philippine flora.
TL;DR: Eight new species are described here, six of which are endemic to Mt Kinabalu, and a new name is established.
Abstract: The genus Elatostema J.R. Forst. & G. Forst. (Urticaceae) is a large Palaeotropical group with perhaps 300 or more species. Eight new species are described here, six of which are endemic to Mt Kinabalu, and a new name is established.
TL;DR: A new species of Secamone (Apocynaceae, Secamonoideae), S. badia Klack, from Sarawak, Malaysia, is described and illustrated and the distinctness of the genera Toxocarpus and Genianthus in relation toSecamone is discussed.
Abstract: A new species of Secamone (Apocynaceae, Secamonoideae), S. badia Klack. from Sarawak, Malaysia, is described and illustrated. The distinctness of the genera Toxocarpus and Genianthus in relation to Secamone is also discussed.
TL;DR: Chromosome numbers and other karyological data of four Stemona spp.
Abstract: Chromosome numbers and other karyological data of four Stemona spp. (Stemonaceae) from Thailand are reported. Three taxa (S. collinsae Craib, S. kerrii Craib and an unidentified species) exhibit 2n = 14 chromosomes, for S. curtisii Hook.f. a range of 2n = 13–16 was established. Based on the counts of c. 30% of the species of Stemona, x = 7 is very likely to be the basic number for the genus. Chromosome size and morphology of the investigated species are compared with literature data and show differences that might be of importance for infrageneric classification. In this connection the taxonomic position of the genus Pentastemona from Sumatra is also discussed.

TL;DR: When going through the herbarium collections from western Africa for the ECOSYN Project, among them was Coccinia longicarpa, a new species described below, easily recognised by its urceolate flowers and long cylindrical fruits.
Abstract: When going through the herbarium collections from western Africa for the ECOSYN Project (see acknowledgement) we came across several not yet published new species. Among them was Coccinia longicarpa described below. Both Keay (1954: 216) and Jeffrey (1964: 87) were, when they prepared a key to the Cucurbitaceae species from West Africa, left with undescribed Coccinia species. These species were at that time insufficiently known. The publication of C. keayana by Fernandes (1959: 191) solved part of the problems left by Keay. More recent collections from Côte d’Ivoire and Ghana made the publication of C. longicarpa possible. The new species is easily recognised by its urceolate flowers and long cylindrical fruits, a combination found in no other Coccinia species so far.
TL;DR: A new monotypic genus from Cambodia described, Khmeriosicyos harmandii, defined by a unique combination of characters and has distinct pollen features.
Abstract: A new monotypic genus from Cambodia is described. The genus is defined by a unique combination of characters and has distinct pollen features. The only species is Khmeriosicyos harmandii W.J. de Wilde & Duyfjes.
TL;DR: As this species was published in 1939 without a latin description, which is required for all names published after 1 January 1935, this name is illegitimate, and Miliusa vidalii, on the contrary, was properly published.
Abstract: When we published the revision of the genus Miliusa in the Flora Malesiana area and Australia, nomenclatorial confusion concerning the species Miliusa vidalii has arisen (Mols & Kesler, 2003: 455). During the process of publishing the sentences “Published without latin description. No validation has been found.” were separated from the true nomenclatorial section. Therefore it appears that this statement refers to Miliusa vidalii. In truth the sentences refer to the synonym Polyalthia pacifica elmer. As this species was published in 1939 without a latin description, which is required for all names published after 1 January 1935, this name is illegitimate. Miliusa vidalii, on the contrary, was properly published.
