Laxe cespitosum, elatum, triunciale, stramineo-lutescens, 
splendens. Caulis crassus, adscendente ramosus ubique, usque

gine infero anguste hyaline limbata, superne serrulato-denticulata, 
nervo basi latissimo latera folii (5/5) superante, e cellulis rectan- 
gulis formato, versus apicem folii cellulis elongatis, subulam totam 
occupante percursa, apice hyalino parce dentato cuspidata, cel- 
luis alaribus quadratis, maxime orbatis, interstitiis fuscis re- 
ceptis, in lamina lutescente, isolatis, inferioribus ovalibus majo- 
rbus, sensim versus apicem folii angustatis, minoribus, ellipticis, 
supremis minutissimis aggregatis.  Catera desunt.
