PLANTS COLLECTED IN JAPAN. 329 



specifically as that of our northwest coast, although the panicle is more densely flowered. The 

 scahrous palese and the very long and tortuous awn are characteristic. The smallest specimen 

 accords, likewise, with Thunherg's description of his Bromus hifidus in its short leaves and 

 pubescent sheaths. The larger specimens are glabrous, except the lower sheaths, and sometimes 

 the rhachis of the panicle. Thunberg, however, states that the spikets are scarcely a line long ; 

 which I suspect is a clerical error, for he describes the pointed tips of the lower paleaj as half a 

 line long, and he hardly would have referred to Bromus a grass, with the aspect of Avena, and 

 with its spikelets only the twelfth of an inch in length. 



Hierochloa borealis, Pcem. & Schult. Hakodadi. In a grave-yard. 



Pennisetum Japonicum, Trin. Ic. Gram. 2, t. 19. Simoda. 



Panicum (isachne) lepidotum, Steud. Syn. Glum. 1, p. 95. Milium globosum, Thunb J 

 Simoda. In the spikets examined, the lower flower was staminate; the upper pistillate only. 



Imperata pedicellata, Steud. Syn. Glum. 1, p. 405. Simoda. Doubtless, only the well 

 known I. arundinacea, which is widely diffused over the world. 



FILICES : By Daniel C. Eaton, of Yale College. 



Equisetum arvense, Linn. Hakodadi and Simoda. 



Drynaria hastata? Polypodium hastatum, Thunb. Fl. Jap., p. 1335 ; Willd. Sp. PI. 5, 

 p. 164. Simoda. 



Drynaria ensata? Polypodium ensatum, Sicartz, Syn. Fil., p. 29. P. Phyllitidis, Thunb. 

 I. c. Simoda. 



Polypodium lineare, Thunb. Fl. Jap., p. 335? Simoda. 



Leptogramma ; the species not determined. Simoda. 



Drymoglossum piloselloides, Presl, Pterid., p. 227. Pteris piloselloides, Linn.; Thunb. Fl. 

 Jap., p. 331 ; Sivartz, Syn. Fil., p. 94, t. 2. Simoda. 



Onychiom Japonicum, Kunze. Simoda. 



Pteris Cretica, Linn. ; Thunb. I. c. p. 334. Simoda. 



Adiantum pedatum, Linn. Hakodadi. The specimens, although too young for proper exami- 

 nation, are apparently identical with the North American species, which extends to Unalaschka 

 and Kamtschatka, and also recurs in the Himalayas. This intermediate station is therefore 

 interesting. 



Woodwardia radicans, Swartz, Syn. Fil. p. ll^. W. orientalis, Siuartz, I. c, &p. 315. 



Woodwardia JjiPONiCA, Sioartz, I. c. Blechnum Japonicum, Thunb. Fl. Jap. p. 333, t. 35. 

 Yokohama or Simoda. Only one imperfect specimen found, which, by the coadunate pinnte, 

 must belong to this species. 



Asplenium ; a delicate species, not identified, but probably not undescribed. Simoda. 



With it was gathered an imperfect specimen of an Athyrium, also not identified. 



Diplazium lanceum, Presl. 1. c. Asplenium lanceum, Tlmnb. Fl. Jap. p. 333. Simoda. 



Cyrtonium falcatum, Presl. I. c. p. 86. Aspidium falcatum, Swartz. Polypodium falcatum, 

 Linn. /.; Thunb. Fl. Jap. p. 336, t. 35. Simoda, Yokohama, and Webster Island ; on rich banks. 



Aspidium (Lastrea): not identified, nor sufficient for description. Yokohama. 



Aspidium (Lastrea) lacerum, Swartz, Syn. Fil. p. 55 1 Simoda. We have only imperfect 

 specimens of an apparently well-marked species, which does not disagree with Thunberg's Poly- 

 podium lacerum.
