Our specimens are usually broader in the frond than the figures 

 above quoted, and the sori are sometimes in a single line near the midrib.

small 



ceeding a foot in length, and the sori are larger than in the normal 



state of P. irioides.

Hab. Foo-chow-foo, along the coast, on trees, rocks, and in moist 

 places, Mr. Alexander. 



I am very doubtful about this species. It very much resembles the 

 Pleopeltis ensifolia, Hook. Exot. FL t. 62, which Presl refers to Pleo- 

 peltis linearis of Kaulfuss, but which Presl himself includes in Polypo- 

 dium. Indeed our own specimens from Foo-chow-foo exhibit varieties 

 or species, some with blunt and some with an acuminated apex ; some 

 with very large, others with small sori ; some have scales on the under 

 side of the frond, others very few or none. They belong to a form of 

 small, simple-fronded Drynaria (or Pleopeltides), which are found in 



different parts of the world, and which require much care to distin- 

 guish specifically. 



4. Drynaria Phymatodes, Fee. Phymatodes vulgaris, Presl. Polypo- 

 dium Phymatodes, Linn. 



Hab. Hongkong, Br. Bill. » 



About 14 inches long in the frond. Our specimens are a common 

 pinnatifid form of this species. 



5 . Drynaria subspathulata ; caudice repente copiose radiculoso, frondi- 

 bus parvis bi- vix tri-uncialibus subcoriaceis costatis lineari-spathu- 

 latis nudis dorso nigro-punctatis basi in stipitem brevissimum atte- 

 nuates marginibus paululum recurvis, soris paucis 4-8 in apicem 

 frondis in duabus lineis seriatim dispositis.
