Luzon Isl., Pr()\. Benguet, Baguio, with th(> type, 

 (ToppiNci no. 1 94). 



The type and variety are very distinct in api)eai'anc(\ and 

 1 was at first inclined to i-egard them as different ferns; l»ut 

 Kilmer's more recent collection connects them fully. 



The i-elationship of this Asplenium is ratiicr mixed. The 

 half -green stipe and rhachis strongly suggests the "viridc" 

 group, and the shape of the pinnae points toward Tric/w?naiies. 

 Judging by the descri])tion, it differs from A. Loherianum 

 Christ, from the same locality, in its larger size, more erect 

 bearing, long stipe, auriculate pinnae and non -rooting apex. 



Its most remarkable feature is tiic torm of the sori, Avliidi 

 are most often confined to the one side of the vein, but l)y 

 no means infrequently are bent across it into the form of 

 a l)r(jad horseshoe. But for the evident nearer affinity to 

 A. viride, and the absence of near relatives in Athijriutii, 1 

 would ])lace it iu the latter genus. The texture of the paleae 

 furnishes no ade(|uate or reliable basis for a generic differen- 

 tiation, and the holding oi Athyrium as a distinct genus seems 

 to me more \ioli'iit than |»iactical.
