Wright 382, the type collection of Solanum pachyneurum var. glabrescens and a syntype of S. pachyneurum, is a mixed collection of S. pachyneurum (e.g., the sheet at BM [BM000886750] is S. pachyneurum) and S. pachyneuroides (also see below). I have chosen the left-hand two stems of GH00112906 (Fig. 4b) to lectotypify the varietal name; the right-hand stem and a small stem in the lower left corner are S. pachyneurum .
