Plante sat robust, virides luridesve, interdum rosez, raro albide, in 
plagas latas unistratas arcte intricatas effusee, vel super muscos palustres 
reptantes iisdemque persepe in cespitem densum implexe. Caules validi 
subteretes, vel prostrati vel per saltus arcuantes et a matrice liberi, ad 
nodos descendentes ope flagellorum radicantes; ramis foliosis posticis, 
cauli conformibus. Cellule in caulis diametro sub 8, corticales 20-22- 
seriate internis conformes et concolores. Folia basi diagonali vel fere 
longitudinali inserta, late ovata vel suborbiculata rotundata, retusa, vel 
rarius emarginata, pro m. concava et integerrima; cellule mediocres— 
minutule, equilatere, cuticula plerumque scaberula. oliola vel nulla

omnia Hucephalozie. Andrecia amentis parvis albidis posticis constantia, 
rarissime robustiora et terminalia.
