Trematocarpus Kützing in southern Africa is found to comprise four taxa in three species: newly described is T.  fragilis (Ag.) De Toni var. divaricatus Simons, var. nov. Two of the species, T. flabellatus (J. Ag.) De Toni and T.  affinis (J. Ag.) De Toni are restored to independent specific rank after being regarded as synonyms of T.  scutellatus (Her.) Searles. It is shown that  Sphaerococcus (Chondrus) scutellatus Her., the basionym of  T.  scutellatus refers to a species of Gigartina, therefore a new combination Gigartina scutellata (Her.) Simons is made for this species which was formerly known as G. fastigiata J. Ag. and G. scabiosa (Kiitz.) Papenf. Trematocarpus elongatus Kiitz. is relegated to synonymy under T. fragilis var.  divaricatus.

This electron microscopy study of the materials from ultraoligotrophic lake Elgygytgyn (Chukotka) revealed variability of morphological features in Hannaea arcus var. arcus and H. arcus var. recta. An emended diagnosis for H. arcus var. arcus is presented, and a new combination in specific rank is published: H. inaequidentata (Lagerstedt) Genkal et Kharitonov (= H. arcus var. recta).

Abstract In the Flora of southern Africa area, comprising the countries of South Africa, Namibia, Botswana, Lesotho and Swaziland, the moss family Sematophyllaceae consists of three genera (Trichosteleum, Donnellia and Sematophyllum) and nine species. Core sematophyllous taxa with collenchymatous exothecial cells, long rostrate operculum, linear leaf cells and differentiated alar cells are included in the family. Meiothecium fuscescens is transferred to Donnellia and a new combination made. Sematophyllum wageri is reduced to synonymy under S. brachycarpum and a lectotype is designated for S. dregei. Each species is described and its distribution mapped.

Six species of the mainly tropical genus Emilia (Asteraceae, Senecioneae) occur in southern Africa. These species are generally not well known as no revision of the genus on a global scale has as yet been undertaken and previous work has focussed on eastern, central and northern Africa. A new combination, Emilia schinzii (syn. E. ambifaria), is proposed here because of priority. Detailed descriptions, distribution maps and a key to the southern African species are presented in this synopsis. Lectotypifications for E. limosa, E. marlothiana, E. schinzii and E. transvaalensis are provided. Included is information relevant to conservation of the species in the form of red data assessments and notes.

The Australian species of two genera, Nothorhaphium, gen. nov. andSyntormon Loew (Diptera : Dolichopodidae), are described, illustrated and keyed, and discussed in context of the Western Pacific fauna. The two genera are phylogenetically close. The Australian Nothorhaphium comprises four species: N. aemulans Becker, comb. nov. (= Xiphandrium pudicum Parent, syn. nov.), N. nudicorne, sp. nov., N. callosum, sp. nov., and N. curalo, sp. nov. The montane New Guinean N. oro, sp. nov. is also described, and its close relationship with the predominantly southern temperate Australian fauna is discussed, suggesting it was part of a common Australian fauna which became isolated with the uplift of New Guinea in the mid–late Tertiary. The Australian Syntormon comprises six species: S. xiphandroides Parent, S. flexibile Becker, S. singularis, sp. nov., S. tasmanense, sp. nov., S. janelithae, sp. nov., and S. lucare, sp. nov. As well, S. aotearoa is described from New Zealand. Genera once thought to be close to Syntormon are discussed. The subfamily Rhaphiinae is briefly discussed, noting the problem of subfamily definition. The New Zealand Syntormon formosus Parent is placed in new combination [= Dactylonotus formosus (Parent)] in a genus previously known only from southern Africa.

Following the most recent phylogenetic analyses of Menonvillea, an updated taxonomic revision of the genus based on molecular and morphological data is presented here. Menonvillea currently includes 24 species distributed in Argentina and Chile. Three new sections, sects. Cuneata, Menonvillea, and Scapigera, are proposed. One subspecies is raised to the specific rank, and the new combination M. marticorenae is proposed. Descriptions, keys to all taxa, updated geographical distributions, maps, and illustrations are provided. Lectotypes for M. filifolia, M. minima, M. purpurea, and M. flexuosa f. tomentosa are designated.

A new species of the southern Africa endemic genus Eliokarmos, that includes the well-known chincherinchees, is described from the vicinity of Kotzesrus, Northern Cape Province of South Africa. Eliokarmos humanii sp. nov. is unique in the genus based on its single, slightly fleshy, suborbicular, convex leaf with ciliate margin, and the short subspiciform inflorescence with almost sessile flowers. A complete description is presented for this species, and data on morphology, ecology, and distribution are reported. In addition, Ornithogalum richtersveldensis, recently described from northwestern South Africa, is transferred to Eliokarmos based on its morphology and biogeography, and a new combination is presented for this species in the latter genus.

Background: Ongoing systematic studies in the African flora necessitate periodic nomenclatural adjustments and corrections.Objectives: To effect requisite nomenclatural changes.Method: Relevant literature was surveyed and relevant material was examined.Results: Nomenclatural adjustments are provided for recently described taxa of Hyacinthaceae subfamily Urgineoideae in order to accommodate them in the alternative classification system in use in South African herbaria.Conclusion: A broadly circumscribed Drimia Jacq. has the advantages of nomenclatural stability and utility. The newly described segregate genera Austronea Mart.-Azorín et al. and Zingela N.R.Crouch et al. are formally included in Drimia, and A. densiflora Mart.-Azorín et al., A. hispidoplicata Mart.-Azorín et al. and A. pinguis Mart.-Azorín et al. are transferred to that genus as D. densiflora (Mart.-Azorín et al.) J.C.Manning Goldblatt, D. hispidoplicata(Mart.-Azorín et al.) J.C.Manning Goldblatt and D. pinguis (Mart.-Azorín et al.) J.C.Manning Goldblatt, respectively, whereas A. grandiflora Mart.-Azorín et al. and A. linearis Mart.-Azorín et al. are treated as synonyms of D. vermiformis J.C.Manning Goldblatt; A. olifanta Mart.-Azorín et al. is treated as a synonym of D. barkerae Oberm. ex J.C.Manning Goldblatt; and A. papillosa Mart.-Azorín et al. and A. pygmaea (A.V. Duthie) Mart.-Azorín et al. are treated a synonyms of D. virens (Schltr.) J.C.Manning Goldblatt. Zingela pooleyorum N.R.Crouch is considered to be conspecific with Urginea zambesiacaBaker, for which the new combination D. zambesiaca (Baker) J.C.Manning Goldblatt is provided. The combination D. zebrina (Mart.-Azorín et al.) J.C.Manning Goldblatt is provided for an allied species. Examination of recent collections of Ornithogalum toxicarium C.Archer R.H.Archer confirms that it is actually a species of Drimia and it is accordingly transferred to that genus as D. toxicaria (C.Archer R.H.Archer) J.C.Manning Goldblatt.

A taxonomic revision of the genus  Ornithogalum L. (Liliaceae) in southern Africa is presented. Three subgenera and 54 species are recognized; 8 of these species are new to science; there is one new subspecies, 3 taxa are accorded subspecific rank, one variety has been raised to specific rank, 4 were taken out of other genera and placed in  Ornithogalum and one was placed under Albuca (see p. 372 for enumeration). Characters separating  Ornithogalum from  Albuca are defined. Historical notes on the genus are given and reference is made to poisonous and cultivated species.
