but I bave no evidence that this featurc is present in ali tbc species. 

 More over tbe rugose appearance is confined to parts of Ibe frond 

 and does not extend over the wbole surface as in Gratcloiipia 

 hieroglyphìca J. Ag. 



6. Myrioglossa Beckeriana. In the text explanatory of tbe plates 

 tbis name is givcn, I prefer to retain it as there is a genus of 

 flowering plants named Myriopkyllum. Concerning this plant D.'' 

 Schmitz considers that it should belong to the Botryoclada section 

 of Chrysymenia because he could not see the delicate cells which 

 fili the lateral leaflets. But as Mr, Batters as well as I bave seen them, 

 and as they are not easily seen except in longitudinal section, 1 think 

 that D/ Scbmitz's opinion is due to imperfect observation. In any 

 case it appears to me that the structure of the frond is nearer to the 

 Cryplarachne section of the genus, than to the Botryoclada and 

 that owing to the distichous arrangement of tbe pinnules it is most 

 conveniently placed in a new genus. 



AUhougb D/ Schmitz sent me only a barren piece of bis cysto- 

 carpis specimen, the babit and structure are so distinct that 1 bave 

 no doubt that bis plant and mine are identical. The similarity of tbe 

 cystocarp is not suljicient of itself to unite genera seeing that several 

 genera of Cryptonemiaceae bave similar cystocarpic fruits.
