The anatomical structure, of the leaf blade as seen in transverse section, and of the abaxial epidermis, of Merxmuellera stricta (Schrad.) Conert is described and illustrated. In this variable species four distinct anatomical “forms” are recognized viz. the typical  M. stricta form, the Cathedral Peak form, the Drakensberg form and the alpine form. The alpine and Cathedral Peak forms have recently been described as M. guillarmodiae Conert (1975). The degree of anatomical differentiation of these “forms” resembles the situation described in M. disticha (Nees) Conert (Ellis, 1980). Populations of both M. stricta and M. disticha from the Drakensberg mountains display extensive anatomical diversification which appears to be correlated with environmental factors. In addition, morphological differences are exhibited as well and the anatomical “forms” of M. stricta probably warrant taxonomic recognition.

After several decades of apartheid rule, which denied human rights to the majority of the population on the ground of race and came to be regarded as a crime against humanity, South Africa adopted its first democratic Constitution in the early 1990s. The 1996 Constitution, which succeeded the 1993 interim Constitution, is considered one of the most progressive in the world. In its founding provisions, it states that South Africa is a democratic state founded on human dignity, the achievement of equality, the advancement of human rights and freedoms. The Constitution enshrines fundamental human rights in a justiciable Bill of Rights as a cornerstone of democracy. Unfortunately, in the eyes of a number of politicians, officials and lay-persons, the rights in the Bill of Rights accrue to South African citizens only. Xenophobia, which has been rampant since the end of apartheid, seems to support the idea that foreigners should not enjoy these rights. Foreign nationals have often been accused of posing a threat to South African citizens with regard to employment opportunities. In light of the South African legislation and jurisprudence, this article affirms the position of the South African labour law that foreign nationals are indeed protected by the Constitution and entitled to rights in the Bill of Rights, including the rights to work and fair labour practices.
