will not do to begin casting doubts on the validity of Geaster "soecics" 

 on the evidence of connecting forms. If you follow uplLtTne of 

 work you will soon have but one or at the best but two spedes left. 

 GEASTER PERUVIANUS (Plate 95 ).-This plant can be de- 



Geaster pectmatus, except that it has an 

 "' in Peru and is preserved at Kew. 





for GE A? T ER MAC9WANI (Plate 9 6.)-This is the South African 

 form of Geaster formcatus. It differs from the type form only h 

 having a furrowed mouth. 



As is now well known, Geasters are divided into two sections 

 those wi h even and those with sulcate mouths. Geaster MacOwani 

 really belongs to neither, being intermediate. I have seen the 4e 

 specimens m the museum at Berlin, and have received specimens from 

 Professor Plottnen Both collections are from South Africa Geas?er 

 formcatus is usually a rare but widely distributed plant. Cfr Lye of
