Pteris Cheilanthoides Hayata, «p. nov. Radix easpi- 

 tosa, stipitibus elongatis 15 cm. longis ebeneis, inferne squamosis, 

 squamis linearibus, frondibus 6-7 cm. longis, 7-8 cm. latis, sub- 

 coriaceo-membranaceis, deltoideis, glabris pinnatis apice acutis 

 subtus albo-glaucis, superioribus non perfecte ad racliin fidis 

 inferioribus subsemideltoideis basi bipinnatis, indusiis marginalibus, 

 linearibus, continuis, suberosis. 



At first sight, this species seems to be Chellanthes argentea 

 Hook ; but studying the plant carefully, I found that the sori are 

 on the intramarginal strand connecting the vein-tij^s, 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 G. 

 argentea Hook, by the frond glaucous beneath, but not farinose.
