25. Pteris cheilanthoides Hayata, 1. c, p. 619. 



Radix caespitosa, stipitibus elongatis 15 cm longis ebeneis, inferne 

 squamosis, squamis, linearibus, frondibus 6—7 cm longis, 7 — 8 cm latis, 

 subcoriaceo-membranaceis, deltoideis, glabris pinnatis apice acutis subtus 

 albo-glaucis, superioribus non perfecte ad rachin fidis inferioribus sub- 

 semideltoideis basi bipinnatis, indusiis marginalibus, linearibus, continuis. 

 suberosis. 



At first sight, this species seems to be Gheilanthes argentea Hook; 

 but studying the plant carefully, I found that the sori are on the intra- 

 marginal strand connecting the vein-tips, but not on the vein-tips 

 themselves. It should, therefore, be referred to Pteris, on account of the 

 position of the sori. Besides, it differs from C. argentea Hook, by the 

 frond glaucous beneath, but not farinose. 



Formosa: Hab. Loco non indtcato, leg. G. Nagasawa, anno 1905.
