 Quoad foliorum formam et caulem gracilem ad A. tiliforrnem ali- 

 quantulum accedens , sed cespitibus compacte pulvinatis robustis , foliis 

 brevioribus supra basin minus patentibus et areolatione grosse rotundata 

 valde incrassata raptim distinctum. Flores masculi in ramo proprio secus 

 axin plures minuti , antheridiis magnis et paraphysibus paucis brevioribus 

 tenuioribus. Folia caulina inferiora magis squarrosa quam superiora juni- 

 perioideo-patula. 



3. Andreaea filiformis n. sp. ; cespites dilatati nigricantes laxe 

 cohaerentes pollicares ; caulis filiformis teuer ramulis permultis dicho- 

 tomis longiusculis fastigiatim divisus , inferne tenerrimus sparsifolius

 vel obtusate acumiuatam producta enervia minuta, e cellulis minutis 

 quadratis basi incrassatis porphyreodermis reticulata intense fuscata 

 glabra. Caetera ignota

 Quoad ramulos filiformes fastigiatim dispositos apice saepius iterum 

 brevissime fastigiatim divisos, folia minuta quadratim reticulata glabra facile 

 distinguenda. Ex habitu formis longirameis filiformibus Andreaeae 

 petropbilae simillima, foliorum reticulatione autem quadrata nee angulato- 

 rotundata incrassata raptim ab eadem recedens. A. obovata scilicet multo 

 robustior et ramis elongatis plus minus teretibus instructa areolatione rotun- 

 data quoque longe diversa.
