Bah. — Ad arborum excisarum prostratarunive truncos putrescentes, 

 rarius in ipsa terra turfosa saxisque, vel supra muscos reptans, 

 totius fere Europte Americfeque borealis, prsecipue in montibus 

 inferioribus ; in Andibus rarissima (vide infra). In Pyrenseis 

 valde abundat, prsecipue ad pedem vallis d' Ossau, prope pages 

 Gelos et Juran^on. 



Folia -85 x -8 ; cell. ^^ ; foliola sup. -5 x -4 ; bracteok int. -9 x -5 ; 

 per 2*4 x •5mm. 



0. Spliagni, prsecipue varietati amazonicm, primo visu sat simile, paulo 

 humilius, csespitosum perssepe rubescens, colore magis in purpu- 

 reum vel etiam in violaceum vergente (nee rubro-miniato sicut in 

 0. Sphagni). Caiidex breviusculus, prostratus aphyllus, totus 

 mtricato-ramosus radicellosus, insuperque flagellis validis radi- 

 cellis villosissimis matrici adfixus. Caules vix pollicares assur- 

 gentes arcuantes, arhizi, rarissime apice flagelliformi radicantes, 

 subramosi ; rami sfepe fasciculati, alii (normales) catdesque hasi 

 plus minus apliylli, deinde foliis ad medium usque sensim crescen- 

 tibus, apicem versus simili modo decrescentibus, vestiti, ex quo 

 rami {semper oligophylli) amhitu lineari-lanceolati evadunt ; aht 

 rami erecti superne sensim 'parvifolia apice gemmipari. 



Folia eadem fere forma ac 0. Spliagni, oblique late ovata vel ovato- 

 rotunda, raro retusa subemarginatave, antice obscure decurrentia, 

 subconcava, assurgentia — non tamen secunda ad 0. Spliagni instar 

 — pellucidiora ; cellulce fere eadem magnitudine magis tamen in- 

 crassata?, cavitate minore ambitu distincte 6-sinuata, endochi'omio 

 parciore, externe parum verruculosoe. Folia surculorum gemmi- 

 parorum euberecta subrotunda, apice varia, rotundata, subacuta, 

 erosave. 



Foliola uhique fere ohvia, ad caules minuta ovata squamseformia, ad 

 surculos gemmiparos insigniter aucta, superiora foliis adjectis cequt- 

 magna—s^pe foliis caulinis mediis vix duplo minora — ovali- 

 rotunda, subintegerrima.
