PTERIDEJE PAESIA. 105 



(45) PAESIA St. Hilaire. 



Rhizome creeping; stipe with a single horseshoe-shaped fibro- vascular 

 bundle; otherwise like Pteridium, except that the extrorse indusium is 

 sometimes wanting, and the spores are bilateral. 



(1) P. rugulosa (LaB.) Kuhn. Stipe and rachises slender, glutinous- 

 pubescent, castaneous; frond quadripinnatifid, rhomboidal; pinnae close, 

 erecto-patent, under 30 cm. long; pinnules close, lanceolate, nearly sessile, 

 1 cm. broad; segments lanceolate, cuneate-truncate on lower side at base, 

 the lower deeply pinnatifid with oblique blunt lobes, subcoriaceous, glutinous 

 and minutely furfuraceous especially below, dull green; sterile segment 

 serrate, fertile with revolute margin, the sorus reaching to the costa. 



Mount Data, Lepanto, in pine forest, Loher. 



New Caledonia, Otaheite ( ?) . 



I do not know this fern, but find nothing in the descriptions to indicate 

 that it has an extrorse indusium; its aspect must be that of Hypolepis, to 

 which it was assigned by Hooker.
