Towards the end of the last millennium when Müller's 1984 field guide, Grasses of South West Africa/Namibia, became sold out, students started relying on South African field guides. This coincided roughly with the untimely death of Mike Müller in a car accident. The void led to frequent misidentification of Namibian grasses as South African ones, some of which do not even occur in Namibia. The void has at last thankfully been filled with the re-publication of Müller's field guide, as revised by Johan van Eck with the help of some of his colleagues at the National Botanical Research Institute (NBRI).
