Segmenta terminalia sterilia obtusiuscula 'erecta aut leviter pa- 

 tentia; in plauta spheerosporifera segmenta terminalia ob sphaerospo- 

 ras grandescentes magis divergunt et ob bases latiores magis acumi- 

 nata adparent; in his ultimis allquando sphserosporam emergentem 

 quoque observare licet.

Habitus Cer. cancellati, at microscopio observata statim diversita- 

 tem prodens. Rami multo magis patentes, terminales divaricati et in 

 apiculum mollem (nec in mucronem) excurrentes. Sphgerosporae in 

 ramulis fere antepenultimis, alio respectu a sterilibus non diversis 

 evolutfe, extra corticem vix prominulee, in verticillo 6 — 8 et plures. 

 In Grunow Novara p. 64. ha3c species jam indicata; me judice nullo 

 modo cum uua aut altei^a forma Capensi C. cancellati conjungenda.
