Addendum. H. pubescens MBB8011, SW Sandberg.
I need to point out that there is a still earlier article which covers Haworthia maculata (Haworthia maculata <–> Haworthia pubescens) that lays the basis for this discussion. In that article I note the position of the Sandberg to Cilmor and DeWetsberg and intended to include the Sandberg H. pubescens in that article. We could not get landowner contact and so that fell away. However, this problem was overcome and we first explored a Dwyka Tillite outcrop southeast of Sandberg. There is a vast accumulation of windblown sand on the first hill and we saw no Haworthia. There is a smaller hill further to the southeast that is also Dwyka and erosion exceeds wind deposition so smaller non-geophytes do quite well. We found both H. herbacea (see fig.1 MBB8014) and H. pumila there. From there we went to the southernmost point of the Sandberg. A misjudgement landed our vehicle in mud and the drama to get out limited the time we had to explore. We found a lone H. herbacea (fig. 2 MBB8012). Returning a week later we approached the Sandberg from the southwest, and almost immediately on reaching the top we found H. pubescent. Fig. 3 is a view towards Cilmor and DeWetsberg where the plants appear to be intermediate H. pubescens↔H. maculata. The picture is useful to get some idea of the role of geographic and geological considerations. The high mountains in the background are Table Mountain Sandstone and no Haworthia is known there. I am not certain that this is true and G J Payne did tell me that he had seen plants on the extreme lower right and south of the Brandvlei Dam. But also on the absolute distant and absolute left, is the Riviersonderend Mt. That is also TMS. The deep Wolfkloof Valley behind that is the locality for the much unexpected H. herbacea ‘lupula’. (These inverted single commas are not entirely necessary but I use them to underscore my informal use of names that have less reality. The var. lupula is real). The mountains ahead of that last line are Hammansberg on the left and the Moddergat to the right. Between there and DeWetsberg has not so far turned up Haworthia, but this is an exploration problem. Behind the DeWetsberg is also underexplored. H. herbacea does occur between DeWetsberg and behind the mountains on the low right just in the picture and also east of the brickfield out further right. H. maculata is only known in this area along the Nekkies north (further to the right) of the Brandvlei Dam just visible in the picture.
