Genus in ordine post Etij)korbiam viistissinnini, PhyUaniho numerosiiis, sod characteribus essen- 

 tiaUbus minus variat, et sat definite limitatur. llaMtu valde polyniorphum eit, sed vix adhiic in 

 sectiones idoneas ab auctoribus dividitur. Klotzsch in variis comnientationiljus genera ultra 20 

 separavit, eed pleraque, ad species unicas definite, a botanicis recentiuribus haud adoptautur e.t 

 auctor nunquam totius generis revisionem edidit. Baillon 11. cc. sectiones 22, plerasque sat naturales 

 proposuit, sed conspectus comparativus nobis deest, et species plurimse postea editse segre includuntur. 

 Mueller Argoviensis sectiones 10 admisit, stricto sensu artificiales et quani maxime insequales. 

 Divisiones ergo scquentes, in Prodromo propositse in Flora Brasiliensi ultorius elaborate clavem 

 exhibent artificialem sed nequaqunm sectiones natnrales existimandjie: —
