 NELLii, n. sp. {D. sublevcogaster, Aust. Exsic. Siippl. I, n. 470, non C. 

 Mull.) — A D. sableucogastri differt ; colore amoene fulvo-viridi, foliis 

 magis apertis subfalcatis longius et magis subito attenuatis apice 

 saepe albicantibiis spiniiloso-serratis, costa angustiori laxiori, etc. 



I), porphyrrodydion, Mitc. proximum ; differt tamen cellulis su- 

 perioribus folii multum brevioribus (minutis quadrato-ovalibus), 

 costa latiori mnltum longius excurrente apice magis serrata, etc. 



Southern Florida, common. Associated with D. gracilica^dis, Mitt. 

 and at least three other species : among them is — 



Dicranum (Campylopus) angustiretis, n. sp.? — Adspectu C. gracil- 

 icauJl versimile, sed foliis inferioribus minus appressis cellulis mul- 

 tum longioribus (sublinearibus) alaribus rufo purpureis temiioribus 

 vahle constrictis, statim distinguitur. 



Leptotrichum homomallum (Hedic.) var.? erosum. — A forma normali 

 differt; foliis eroso-serratis. Plantae utriusque sexus in eodem caespite: 

 sterile. (An species distincta?)

 Smitli. 



Stems slender and scarcely exceeding an inch in length ; the young- 

 er ones lightly clothed with a delicate entangled white tomentum. 

 About one half of the expanded portion of the leaf is composed of

 rapidly become much narrower and longer. The basal cells, although 

 much enlarged are not inflated. There appear to be no true alar
