Stem Structure

A new species, Rhexoxylon piatnitzkyi is described and illustrated. It is a small stem showing the primary organization of the vascular cylinder and has enabled the authors to present a new interpretation of the development of the complex mature stem structure of Rhexoxylon . Together with further specimens of larger stems described provisionally as Rhexoxylon sp.A the material has revealed new anatomical details. The diagnosis of Rhexoxylon and of R. tetrapteridoides Walton are emended. R. waltonii Kräusel is reduced to a synonym of R. africanum Bancroft. R. priestleyi (Seward) Walton is restored to Antartic-oxylon Seward because of differences judged to be of generic value. The affinities of Rhexoxylon are discussed. The present record from Triassic strata in north-west Argentina is the first occurrence of Rhexoxylon outside Africa and supports a stratigraphical correlation of the beds (Ischigualasto Formation) with the Stormberg Series of South Africa.

A New Species

Haroldius lyleae Daniel, Strümpher & Snäll, new species, is described and illustrated from South Africa. The new species can be easily distinguished from other species of the genus by its notable triangular clypeus lacking the distinctive mid-anterior indentation and denticles present in other Haroldius Boucomont, 1914 species. Monomorium albopilosum Emery, 1895 (Hymenoptera: Formicidae: Myrmicinae) is recorded as a possible ant host of the new species. Haroldius modestus (Janssens, 1953) is recorded from Zimbabwe for the first time, and Haroldius convexus (Philips & Scholtz, 2000) is now recorded from the North West and KwaZulu-Natal Provinces of South Africa as well.

A New Species

The genus Trimelopter has been recently reinstated to include Ornithogalum unifolium and other closely related species from Southern Africa, comprising up to 10 species. Within the context of a revision of Trimelopter, a new species, T. craibii, is here formally described to name plants discovered by the late Charles Craib in the North West Province of South Africa. This taxon is closely related to T. dyeri and T. unifolium, but it can be clearly differentiated by floral and vegetative characters. Data on morphology, ecology, and distribution are reported for this new species, and affinities and divergences with other closely related taxa are also discussed. The new combination T. unifolium var. vestitum is also proposed.

A New Species

Frithia N.E.Br (Mesembryanthemaceae), formerly thought to be a monotypic genus, has been found to comprise two species. Populations from the eastern parts of the distribution range of Frithia pulchra N.E.Br. are recognised as a distinct species,  Frithia humilis PM Burgoyne The genus has a limited distribution, although present in three provinces of South Africa, namely Gauteng, North-West and Mpumalanga. The two window-leaved species are allopatnc and morphological differences between the roots, leaves, flowers, pollen, capsules and seeds are discussed. A formal description of the new species, an identification key and a distribution map of the two species are provided.

General Appearance

I have received from South Africa specimens of blood taken from cattle which contain a new species of Trypanosoma. This new species can be at once distinguished from the Trypanosomas of Surra, Tse-tse Fly Disease, or Rat by its larger size, it being almost twice as large as any of the others. In general appearance it conforms closely to the others in possessing an oval protoplasmic body, a longitudinal fin-like membrane, and a single flagellum.

A New Species

About thirty years ago a species of manna, obtained from the Eucalyptus Mannifera, was brought from New South Wales, and was examined by Dr Thomas Thomson, and afterwards by Professor Johnston, both of whom ascertained it to contain a new species of sugar, different from the mannite which exists in ordinary manna. The author had, through the kindness of Mr Sheriff Cay, an opportunity of examining a very different species of manna, remarkable both from its chemical constitution, and from its possessing a definitely organised structure. This substance was discovered by Mr Robert Cay in 1844, in the interior of Australia Felix, to the north and north-west of Melbourne, where it occurs at certain seasons on the leaves of the Mallee plant, Eucalyptus Dumosa, and is known to the natives by the name of Lerp.
