S. petersianus, var. grandiflorus, was based in the first place on s))cciiuens 

 <-ollecte(l by Montciro in Delap^oa Hay. They at least suggested the name, and a 

 plant raised from seeds of the same origin was subsequently figured in Bot. Mag. t. 

 7390 as re])resenting this variety. Unfortunately other si>ecinieiiis, some of which 

 were described simultaneously and independently by Pax as S. sarmeniosus, var. 

 verrucosus, were mixed up with the Delagoa plant. I agree with Gilg in consider- 

 ing Pax's variety verrucosus as specifically distinct from S. sarmentosus ; but 

 it differs just as much from the Delagoa plant, for which the name grand iff ortis 

 may appropri itcly be retained, designating it as a distinct species.
