Bruguiera × dungarra (Rhizophoraceae), a previously undescribed hybrid species between B. exaristata and B. gymnorhiza is recorded from north-east Australia. Eight taxa are currently recognised in this Indo West Pacific genus, including three putative hybrids. The newly described hybrid is widely occurring, and it is described here with notes provided on typification, phenology, distribution and habitat. A revised identification key to all Bruguiera taxa is presented, along with a table of comparative diagnostic characters.

A taxonomic revision of the genus Sapranthus is presented. Within the genus Sapranthus 8 species are recognized, 2 of which are new. Distinguishing morphological characteristics are discussed, and a dichotomous key to all species is given. The species treatments include descriptions, full synonymy, geographical and ecological notes, vernacular names, and taxonomic notes. Distribution maps are presented of all species, and a complete identification list of exsiccatae examined is included.

Trigonostemon is taxonomically revised for Malesia based on herbarium collections and field observations. Thirty-eight species are recognized in Malesia, of which four of uncertain status and four newly described. The previous infrageneric classifications are briefly reviewed, but none is accepted. Some useful characters are discussed. An identification key, nomenclature, descriptions, typification, geographic distributions and taxonomic notes are provided.

A review of new data relating to Nepenthes insignis in Indonesia indicates that three taxa in section Insignes, not one, are present in New Guinea. One of these, endemic to the limestone of the island of Biak, is formally named as Nepenthes biak and assessed as Critically Endangered; the other, from limestone of the Raja Ampat islands is provisionally distinguished as Nepenthes sp. Raja Ampat, since only images are available.

In preparing the treatment of Dracaena for Flore du Gabon and Flore d’Afrique centrale, a relatively high number of taxonomic and nomenclatural novelties were discovered; these are presented here. Within Dracaena five species and one forma are described as new, D. bushii, D. haemanthoides, D. marina, D. wakaensis, D. waltersiae and D. laxissima forma aureilicia. Each new species is provided with a full description and taxonomic notes. Apart from that, five species are reinstated, D. braunii, D. nitens, D. perrottetii, D. tholloniana and D. usambarensis. A further 23 names are treated here as a synonym for the first time: D. bequaertii, D. buettneri, D. cuspidibracteata, D. densifolia, D. gabonica, D. gazensis, D. ledermannii, D. letestui, D. litoralis, D. longipetiolata, D. monostachya var. angolensis, D. oddonii, D. perrottetii var. minor, D. poggei, D. pseudoreflexa, D. reflexa var. buchneri, D. rubroaurantiaca, D. soyauxiana, D. talbotii, D. tessmannii, D. usambarensis var. longifolia, D. vanderystii and Pleomele heudelotii, while for four names a neotype and for 14 names a lectotype has been designated. Distribution maps are provided for a total of 23 species. An index of taxon names is included.

A new species, Rubus ramachandrae, from Upper Subansiri district of Arunachal Pradesh, India is described and illustrated. It is closely similar to R. stipulosus and R. fuscifolius but differs by densely bristly or hirsute branches; narrowly ovate or oblong-lanceolate leaves with caudate-acuminate apex and adaxially hirsutulous vesture; abaxially grey tomentose intermixed with hirsutulous hairs; larger size of stipules and bracts with distinct margin and vesture; smaller size of floral structure. The distinct foliar as well as floral morphology of R. ramachandrae differs from all previously described species of Rubus. Differences in key morphological characters of R. ramachandrae, R. stipulosus and R. fuscifolius are also tabulated. In addition, pollen morphology is described based on light (LM) and scanning electron (SEM) microscopy. Based on the presence of straggling shrubby habit, free stipules, simple leaves, reflexed and strong needle shaped prickles, the new taxon is assigned to Rubus subg. Malachobatus. An image of the type specimen; digital images of habit, stipule, inflorescence and flower, a detailed illustration and scanned electron microscope images of pollens are provided.
