F. CELLULOSES, sp. n. Pusillus flaccidus decumbens ; folia 

 alterna oblongo-lanceolata acuta ubique limbo e dupHci serie 

 cellularum anguste marginata, nervo angusto obscuriore infra 

 apicem evanido ; cellulis magnis oblongo-bexagonis pellucidia 

 areoiata. 



Hab. TIsagara Mountains, on the earth, Bishop Sanninr/ton.

These very incomplete specimens indicate the presence of 

 another species of that small group which contains F. hyalinus^ 

 F. deolhatuSj and the Conomitrium (§ Polypodiopsis) Metzgeria^ 

 C. MiilL, with a very lax pellucid areolation and an incomplete 

 or obsolete nerve. 



Plagiochila, Nees et Mont. 



P. saeme:n^tosa, Lehm. 



Sab. Kilimanjaro, Bisliop Sannington. 



The specimens are larger than those figured by Lindenberg, 

 and in this they agree with some collected on Table Mountain 

 by Mr. Eaton. Other specimens still more elongate have been 

 collected at Fernando Po, Mann^ on the Niger, Barter j and 

 closely similar ones were sent out of M. Bojer's herbarium at 

 Mauritius by Dr. Ayres. All these seem to be really states of 

 one species, which varies in colour and in stature, but very little 

 in the outline of its leaves, which is similar to that of the European 

 -P. asplenioides.
