    Re-shaping Mallotus [Part 2]: inclusion of Neotrewia, Octospermum and Trewia in Mallotus s.s. (Euphorbiaceae s.s.) (2007)

    Beschreibung: A recent molecular phylogenetic study of Mallotus and related genera showed that three small Asiatic genera are clearly part of a strongly supported main Mallotus clade (Mallotus s.s. clade), rendering the genus paraphyletic. In this paper these genera, Neotrewia, Octospermum and Trewia, are merged with Mallotus. The monotypic Neotrewia and Octospermum were originally described within Mallotus and are now transferred back to it. Trewia was never included in Mallotus; it has two distinct species, for which new combinations within Mallotus are made. A full taxonomic treatment with descriptions, distribution maps and drawings is given for the species transferred, and a new generic description for Mallotus is provided. The morphology of the newly transferred species in comparison to Mallotus in general and to related species in particular is discussed.

    A taxonomic survey of seaweeds from Eritrea (2005)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (0006-5196) vol.50 (2005) nr.1 p.65
    Details
    Publikationsdatum: 2015-03-06
    Beschreibung: A survey of seaweeds was made in Eritrea in December 1995 and January 1996 on some islands of the Dahlak Archipelago and the surroundings of the port town of Massawa. During our study 101 specific and infraspecific taxa were identified, including 26 Chlorophyta, 20 Phaeophyta and 55 Rhodophyta. The survey resulted in 36 new records for Eritrea (11 Chlorophyta, 7 Phaeophyta and 18 Rhodophyta). Of these Eritrean records, 26 are new for the Red Sea (5 Chlorophyta, 4 Phaeophyta and 17 Rhodophyta). Comparison of records of seaweeds from localities in Eritrea to those from other localities in Eritrea as well as from other coasts of the western Indian Ocean have revealed that the regional distribution of seaweeds in the Red Sea is very patchy and that generally the area seems to be undersampled. The comparisons have also underscored the stressful seasonal environmental conditions for macroalgae in the southern Red Sea.

    Gulella johannae spec. nov. (Gastropoda, Pulmonata, Streptaxidae), a new land snail from the Drakensberg range in Limpopo Province, South Africa, with notes on G. johannesburgensis (M. & P.) (2006)
    In:  Zoologische Mededelingen (0024-0672) vol.80 (2006) nr.1 p.63
    Details
    Publikationsdatum: 2010-12-12
    Beschreibung: Gulella (s.l.) johannae n. sp. is described from a few forest localities in the Tzaneen District, Limpopo Province, South Africa. It is characterized by a cylindrical, costulate shell with an almost entire peristome and a four-fold apertural dentition consisting of a prominent angular lamella (delimiting an only here discontinuous peristome), a mid-labral denticle, a left basal denticle, and a mid-columellar process. The shell is somewhat similar to that of G. johannesburgensis, but is consistently larger and more slender and has more whorls, while at the same time the apertural dentition is better developed; the almost uninterrupted peristome also appears to be a signifi cant character. This new taxon most likely is a restrictedrange endemic on the eastern flanks of the northern Drakensberg escarpment. Numerical data of a lot of material identified and mostly also published as G. johannesburgensis show that probably not all specimens belong to this taxon so that more than one species may be involved here.

    A taxonomic revision of Mallotus section Philippinenses (former section Rottlera – Euphorbiaceae) in Malesia and Thailand (2005)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (0006-5196) vol.50 (2005) nr.2 p.221
    Details
    Publikationsdatum: 2015-03-06
    Beschreibung: A revision of Mallotus section Philippinenses (former section Rottlera) in Malesia and Thailand is given. Descriptions, distribution maps, habit drawings, and a key to the species are provided. The diagnostic characters for the section are briefly discussed. Five species (M. kongkandae, M. leptostachyus, M. pallidus, M. philippensis, and M. repandus) are recognised. Mallotus chromocarpus is excluded from the section because it has more shared characters with the monospecific genus Octospermum, like the presence of indehiscent fruits, absence of stipules, marginal extrafloral nectaries on the upper side of the leaf blade, broad connectives (shaped umbrella-like), and its occurrence in New Guinea, and is therefore probably closely related to it.
