Relationship Of

Generic circumscriptions and phylogenetic relationships of the Cape genera Capnophyllum, Dasispermum, and Sonderina are explored through parsimony and Bayesian inference analyses of nrDNA ITS and cpDNA rps16 intron sequences, morphology, and combined molecular and morphological data. The relationship of these genera with the North African genera Krubera and Stoibrax is also assessed. Analyses of both molecular data sets place Capnophyllum, Dasispermum, Sonderina, and the only southern African species of Stoibrax (S. capense) within the newly recognized Lefebvrea clade of tribe Tordylieae. Capnophyllum is strongly supported as monophyletic and is distantly related to Krubera. The monotypic genus Dasispermum and Stoibrax capense are embedded within a paraphyletic Sonderina. This complex is distantly related to the North African species of Stoibrax in tribe Apieae, in which the type species, Stoibrax dichotomum, occurs. Consequently, Dasispermum is expanded to include both Sonderina and Stoibrax capense. New combinations are formalized for Dasispermum capense, D. hispidum, D. humile, and D. tenue. An undescribed species from the Tanqua Karoo in South Africa is also closely related to Capnophyllum and the Dasispermum–Sonderina complex. The genus Scaraboides is described herein to accommodate the new species, S. manningii. This monotypic genus shares the dorsally compressed fruit and involute marginal wings with Capnophyllum, but is easily distinguished by its erect branching habit, green leaves, scabrous umbels, and fruit with indistinct median and lateral ribs, additional solitary vittae in each marginal wing, and parallel, closely spaced commissural vittae. Despite the marked fruit similarities with Capnophyllum, analyses of DNA sequence data place Scaraboides closer to the Dasispermum–Sonderina complex, with which it shares the erect habit, green (nonglaucous) leaves, and scabrous umbels.

A Collection of ticks from British Somaliland recently sent to the British Museum (Natural History) contained specimens of a species of Ornithodoros unlike any in the national collection and (from the appearance of the integument) related to the North African species O. foleyi Parrot (from Algeria) and O. delanoëi Roubaud & Colas-Belcour (from Morocco). The late Prof. G. H. F. Nuttall presented to the Museum a specimen of O. foleyi, and the writer is indebted to Prof. E. Roubaud for comparing one of the present specimens with the type of O. delanoëi. Prof. Roubaud writes to say that, having examined the Somaliland specimen, he and M. Colas-Belcour are of the opinion that it belongs to the species O. delanoëi: and that the various details of structural difference do not warrant a specific distinction, but indicate that the present specimens may belong to a different biological or geographical race. The large size of these Somaliland ticks, the discovery of their larvae and their presence in a locality so widely separated from that of the type, are considered important enough to be placed on record, and the specimens are regarded as representing a subspecies of O. delanoëi

A comparison of endemic Lathyrus species of different continents has been carried out with regard to venation, epidermal cell structure, and number of leaflets to apply the information so obtained to phylogenetic considerations. Morphologically primitive Lathyrus species have several leaflets with pinnate venation, and epidermal cells with undulate walls. This type is represented by all the North American endemic species and by some Eurasian ones. Most Eurasian and North African species, however, have only one pair of leaflets, parallel venation, and epidermal cells with undulate walls. The South American species are the furthest advanced in evolution. They have two leaflets with parallel venation, and epidermal cells with straight lateral walls. The endemic species of South and North America thus differ sharply with regard to the characteristics examined while Eurasian and North African species show relationship to species of both South and North America. The distribution of the leaf characteristics studied and evolution of species within this genius might have its cause in historical geology.

In this paper the North African species of the genus Oiketicoides Heylaerts, 1881, are revised. In total there are 16 species of which Oiketicoides algeriensis sp. nov., Oiketicoides albomaculatus sp. nov., Oiketicoides pseudochottella sp. nov., Oiketicoides numidicum sp. nov., Oiketicoides maroccensis sp. nov., Oiketicoides maghrebensis sp. nov., Oiketicoides imazigheni sp. nov. and Oiketicoides atlanticum sp. nov. are described here as new for science. The subspecies described as Oiketicoides febretta lambessa (Heylaerts, 1889) is treated here as belonging to the species rank and a lectotype is formally fixed.

AbstractGenetic variation within the North African toad Bufo mauritanicus was estimated by sequencing partial 12S rRNA and 16S rRNA mitochondrial regions from widespread populations in Morocco, Algeria and Tunisia. Unlike many other wide ranging species from this area, B. mauritanicus demonstrated very low levels of intraspecific variation. The minimal intraspecific genetic variation may be due to a relatively recent, possibly post-glacial, expansion into its current range. Further phylogeographic studies of other North African species are needed to assess if this is a common biogeographical phenomenon. Phylogenetic analyses support immunological data that B. mauritanicus is part of a clade of predominantly sub-Saharan Bufo, recently assigned to a new genus Amietophrynus. Two different lineages within this clade, B. mauritanicus and the B. pardalis group, appear to have reverted from 20 chromosomes to the more typical 22 chromosomes found in most other Bufonids. However, the alternative hypothesis that the Bufo species with 20 chromosomes form a monophyletic lineage cannot be rejected.

Inflammatory Effect

The seeds of Ammodaucus leucotrichus Cosson and Durieu have been used in the North African Sahara as a traditional medicine to treat diabetes. The present study investigates the antidiabetic, antihyperglycemic, and anti-inflammatory properties of the defatted hydroethanolic extract of Ammodaucus leucotrichus (DHEAM). The antidiabetic and the antihyperglycemic studies were assessed on alloxan-induced diabetic with orally administered doses of DHEAM (100 and 200 mg/kg). At the same time, its anti-inflammatory propriety was evaluated by measuring edema development in the Wistar rats paw induced with carrageenan. Treatment of diabetic mice with DHEAM for four weeks managed their high fasting blood glucose levels, improved their overall health, and also revealed an excellent antihyperglycemic activity. Following the anti-inflammatory results, DHEAM exhibited a perfect activity. HPLC results revealed the presence of seven molecules (chlorogenic acid, 3-p-coumaroylquinic acid, gallic acid, ferulic acid, myricetin, quercetin, luteolin). This work indicates that the DHEAM has an important antidiabetic, antihyperglycemic, and anti-inflammatory effect that can be well established as a phytomedicine to treat diabetes.
