We see no reason for Turner's genus Staurophanum, as no clear 

 line of demarcation can be drawn between those species which it 

 would include and those referable to Tetraedron. Indeed Tetraedron 

 pusillum is very closely connected through its var. angolense with 

 T. lobidatum (Niig.) Hansg.
