may i9io.] TAKEDA.—NOTULAS AD PLANTAS NOVAS. 113 



Hasc dubia et insignis species Pox Fauriei Hack., quae mihi 

 solum ex descriptione nota est, affinis esse videtur. Sed et a 

 Poa et a Colpodio in multis rebus distinguitur. Oportet, ut 

 opinor, genus novum proponi.

The occurence of this plant in Japan has not yet been recorded 

 for the first specimens collected in Japan by Prof. Dr. K. Miyabe 

 at Sharisando, in the province of Kitami, in the island of Yezo, 

 on the 21st. July 1884, were erroneously named Aspidium spinu- 

 losum var. dilatatum (= Dryopteris dilatata A. Gr.). In fact 

 our plant resembles Drypoteris dilatata var. deltoideum, from 

 which it is, however, easily distinguished by the shape and colour 

 of the scales and the structure of the pinnee and pinnules. This 

 fern is fully described by Milde on the above cited page.
