This article analyses the judgment of the Supreme Court of Poland of 25 June 2020, in which the Court refused to recognise registered mail receipt forms issued by the authorities of the so-called Turkish Republic of Northern Cyprus (TRNC) as foreign official documents, despite the Public Prosecutor General and the claimant arguing to the contrary. The text attempts to show that the ruling is consistent with earlier Polish practice and the majority view in domestic literature. Still, the international jurisprudence shows that there is no clear rule of public international law that would make non-recognition of documents absolutely mandatory in such cases, and some exceptions could even support their recognition under special circumstances. Also, in similar cases foreign national courts do not always refuse recognition.

The purpose of this article is to establish a frame for arranging and classifying observations relating to the indigenous knowledge and oral traditions of the San people of southern Africa, mainly in Namibia. Oral literature of the San people serve, therefore, as a valuable source for re-constructing and reinforcing a positive collective identity of their history and cultural diversity. Several forms of expression such as folklore, poems, plants' names and personal narratives will be provided.

Members of the Nyctaginaceae Jussieu. are distributed throughout southern Africa. Eight species of the family occur naturally in arid parts of Namibia. These species have acquired the ability to survive and reproduce in these dry conditions. They are xerophytes, which have been described as drought evaders, avoiders, and drought-tolerant. In the Nyctaginaceae, Boerhavia deserticola, B. hereroensis, Commicarpus helenae and C. squarrosus are thought to be drought avoiders. In this study we investigated their stem, leaf and anthocarp anatomy for adaptations to arid environments. The results indicated that the four species are avoiders, with modifications of the trichomes, secretions, crystals, secondary growth, Kranz mesophyll, water storage cells, tannins, mucilage, inner and outer stomatal ledges, large-diameter xylem vessels, and the presence of sclerenchyma in their stems, leaves and anthocarps. These adaptations enable the plants to tolerate arid conditions, conserve water and maintain a high photosynthetic rate, and aid seed dispersal.
