leaves, fa far as they are reprefented, are placed in the fame manner 

 as in the annexed figure. 



I ihall now fubjoin a fhort defcription of it under the name of 



Jungermannia/0;?//<7. Tab. 20. Fig. 1. 



J.furculis pinnatis ramofis medio floriferis, fioribus fubfcflilibus, 

 vaq;mis obovatis inflatis. 

 Habitat in Pennfylvania. 



Descr. Surculi decumbentes ramon. Folia alterna, obovata, 

 perforata, pellucida, fubtus auriculata. Vagina fubpedunculata in- 

 flata, exiguis aliquot ad bafin fquamis cincta. Seta breviflima. 



The Splachnum which I received at the fame time with the above, 

 when compared with Dillenius's fpecimen, proved to be the Sphag- 

 num figured in Tab, 85. f. 15*5 — the figure is remarkably fliff. 

 This is made a Phafcum by Linnaeus ; but with equal impropriety, 

 it being a true Splachnum. 



Splachnum caulefcens. Tab. 20. Fig. 2. 



Spl. caulefcens, foliis linearibus apice fetaceis. 

 Habitat in Pennfylvania. 



Descr. Caules filiformes erecti ; folia alterna, inflexa, reticulata,, 

 pellucida ; capfula erecta cylindrica.
