illis interdum confusti, snepinsime tnmen accurate distingiiltiir capstilne dchi^centia semiuum strnctura 

 numero et situ, ssepeque calyce aliisque notis, et genus nullum revera intermedium nobis notum est-

Quoad specierum distribution em in genera et tribus confusio maxima prsevaluit, quam Nees ab 

 Eseobeck assiduo labore per plurea anuos partim expedivit ; genera tamen (in DC, Prod, xi.) inordi- 

 nate multiplicavit, nee semper eharacteribus certis distinxit, et species non paucse ab auetore ipso in 

 diversis herbariis examioatae in diverfeis generibue repetit£e oeciirrunL T, Anderson poetea Acan- 

 Mrtf?m5 gerontogeas (in /oiirn, Linn. Soc. vii. et ix.) in genera et niagis naturjtlia et meljuy limitata 

 ordinavit, sed morte praematura ablatus opus imperfectum r*^liquit, characteribus genericis nondum 

 elaboratis. Nos pro parte Neej^ium sa^piuB tamen Andcrsonium seciiti tumus, e.g. sestivationem
