A small plant from the same locality growing among P. hastata and 

 P. calomelanos (No. 183rf) possesses characters common to the two 

 plants which led Dr. Welwitsch to question the value of the species. 

 This plant has the habit of P. hastata Link., but the segments are 

 scarcely subcrenate, the rachis is not winged, and the veins in the 

 segments are inconspicuous as in L. calomelanos Link. Welwitsch 

 suggests that it may be the plant named Pteris leucomelas Mett. in 

 Kuhn, Fil. Afr. p. 83.
