Caulis pendulus, decrescente breviter ramosus pallide viri- 
dis, ramis obtusis teretibus dense foliatis. Folis caulina laxe 
appressa obovata, marginibus incurvis cochleariformi-concava 
piliforıne acuminata integerrima, basi excavata auriculata; nervo 
tenuissimo concolore supra medium folii producto; cellulis ala- 
ribus numerosis conglobatis subquadratis pellucidis, caeteris 
linearibus dense aggregatis, versus apicem folii übbrevistis; 
ramorum folia dense imbricata, caulinis conformia, brevius acu- 
minata, laxius retieulate, in caeteris simillima;, folia perichae- 
tialia concava ovato-lanceolats acuminata, integerrima. Seta 
brevis. Theca ovalis, intense cuprea; peristomium connivens, 
densibus externis lanceolatis nodoso-trabeculatis, internis ciliis 
subwlatis coloratis brevioribus; caetera desunt.
