Antrophyum Perrierianum C. Christensen sp. nov. 



Région lloristùine du Centre. Ankaizina . Vers 1 Joo mètres 

 d'altitude. Sur les troncs dans la mousse. 

 Octobre ifjoS. .V 7S67. 



DIAG.NOSE ORIGINALE. 



Species anterioribus habita omnino similis, viltarii- 

 formis. 



Foliis ad 10 cm longis, 2-3 mm latis, coriaceis, raargi- 

 nibus revolutis. Venis reticulatis, 3-4 séries areolarum 

 formantibus, costa niilla. 



Soris saepe venas exteriores solum occupantibus, duas 

 lineas submtirginalibus a marginibus obtectis formanti- 

 bus, sed interdum recticulatis, paulo vel vix immersis. 



Obs. I. The spécimen seen is a poorone, and without 

 soakening the leaf for making the venation visible, one 

 should be inclined to believe it to be the same as 

 A. trivittatum. It has, however, a distinct reticulate 

 venation as in other species of Antrophvum. It connects 

 the sabgenus Bathia with Antrophyopsis Benedict.
